About Mountainside Hospital Outpnt Behavioral

You can find the Mountainside Medical Center – Behavioral Health Services on the fourth floor of the Mountainside Medical Center in Montclair, New Jersey. The main hospital provides primary healthcare services, emergency care, audiology and cardiac health services. Their specialists also offer cosmetic and plastic surgery, dental services and diagnostic and testing services. The behavioral health branch specializes in treating substance use disorders, eating disorders and mood disorders like anxiety, depression and bipolar disorder.

Mountainside provides inpatient and outpatient therapy programs, a partial hospitalization program and an intensive outpatient program for those who aren’t eligible for the partial hospitalization program. During the intensive outpatient program, you’ll attend individual and group therapy sessions three times a week in the morning.

Their inpatient unit has space for 30 adults. On top of caring for those experiencing addiction to alcohol or drugs, they also look after anyone experiencing psychosis or paranoia, living with bipolar or ADHD, and going through adjustment disorder.

Their outpatient services are available to children aged five and up, adolescents, adults and seniors. The program involves individual therapy and group sessions.

A great feature of this center is that all of their psychiatrists are trained to provide quality geriatric mental health support to older patients. Many addiction treatment centers have age limits that prevent seniors who are experiencing addiction from getting the help they need. This center aims to provide seniors with a vibrant and fulfilling recovery experience. The program is designed to be an efficient, short term solution that stabilizes your condition enough for you to return to your normal life. Their services include traditional therapy methods like cognitive behavioral therapy and addiction groups, as well as contemporary treatments like music therapy and recreational therapy.

A family member needed to access dialysis in the Mtc area and Mountainside Dialysis Ctr proved to be the most convenient, accommodating and full-service option, being centered as part of a long-established hospital.First off, the management team here was great. Literally NO ONE wants to be here - much less 3x per week for 3.5 hrs per session - yet they make the process manageable (I would never say "a delight"). Mountainside has s great staff of pleasant nurses & techs; more privacy than you'd find at DaVita/Fresenius facility; a seat covered with a fresh sheet btwn each visitor (most facilities don't freshly "re-sheet" their seats in btwn visitors; they simply wipe them down with alcohol and it's next patient up - while not an unclean process, it''s clearly NOT as sanitized as a clean sheet covering the seat) and a warm blanket to use for the day. This ain't "Cheers", but if you must become a regular at a spot to keep yourself going, this is a good place to be.Byond the actual treatment services, my family has come to appreciate the management team - namely Elsie & Liz - and their Admin/non-nurse team. They've answered countess questions, calmed countless nerves and have been real "people", not simply "admin." We appreciate the touch.Note: If you use the Dialysis Ctr (only), there is "free" valet parking in front of the facility. It's done by tip so while $2-5 will get you done, I generally give the staff a $5. I feel like they deserve it.Best advice I can offer you is: Don't experience renal failure!!Second best advice I can offer: If you do, strongly consider using Mountainside Dialysis - it trumps DaVita & Fresenius for treatment.Lastly, a prayer for you or your family member dealing with this insidious condition. May you stay positive & beat it!

Other Forms of Payment

Self-pay involves paying for treatment out of your own pocket. You can use savings or credit, get a personal loan, or receive help from family and friends to fund your treatment. If you don't have insurance or your insurance plan doesn't cover a specific program, self-pay can help ensure you still get the care you need.

Financial aid can take many forms. Centers may have grants or scholarships available to clients who meet eligibility requirements. Programs that receive SAMHSA grants may have financial aid available for those who need treatment as well. Grants and scholarships can help you pai for treatment without having to repay.

Private insurance refers to any kind of healthcare coverage that isn't from the state or federal government. This includes individual and family plans offered by an employer or purchased from the Insurance Marketplace. Every plan will have different requirements and out of pocket costs so be sure to get the full details before you start treatment.

Military members, veterans, and eligible dependents have access to specific insurance programs that help them get the care they need. TRICARE and VA insurance can help you access low cost or no cost addiction and mental health treatment. Programs that accept military insurance often have targeted treatment focused on the unique challenges military members, veterans, and their families face.

Addiction Treatments

Levels of Care

outpatient iconOutpatient
Outpatient Programs (OP) are for those seeking mental rehab or drug rehab, but who also stay at home every night. The main difference between outpatient treatment (OP) and intensive outpatient treatment (IOP) lies in the amount of hours the patient spends at the facility. Most of the time an outpatient program is designed for someone who has completed an inpatient stay and is looking to continue their growth in recovery. Outpatient is not meant to be the starting point, it is commonly referred to as aftercare.

Treatments

The goal of treatment for alcoholism is abstinence. Those with poor social support, poor motivation, or psychiatric disorders tend to relapse within a few years of treatment. For these people, success is measured by longer periods of abstinence, reduced use of alcohol, better health, and improved social functioning. Recovery and Maintenance are usually based on 12 step programs and AA meetings.

Drug rehab in New Jersey is the process of addressing the complex issues involved with addiction. Challenges are identified and addressed through individual and group counseling. Participants learn how to manage these issues without the use of substances.

A combined mental health and substance abuse rehab has the staff and resources available to handle individuals with both mental health and substance abuse issues. It can be challenging to determine where a specific symptom stems from (a mental health issue or an issue related to substance abuse), so mental health and substance abuse professionals are helpful in detangling symptoms and keeping treatment on track.

Opioid rehabs specialize in supporting those recovering from opioid addiction. They treat those suffering from addiction to illegal opioids like heroin, as well as prescription drugs like oxycodone. These centers typically combine both physical as well as mental and emotional support to help stop addiction. Physical support often includes medical detox and subsequent medical support (including medication), and mental support includes in-depth therapy to address the underlying causes of addiction.

Programs

adult-program thumbnail image
Adult Program
Adult rehab programs include therapies tailored to each client's specific needs, goals, and recovery progress. They are tailored to the specific challenges adult clients may face, including family and work pressures and commitments. From inpatient and residential treatment to various levels of outpatient services, there are many options available. Some facilities also help adults work through co-occurring conditions, like anxiety, that can accompany addiction.
young-adult-program thumbnail image
Young Adult Program
Young adulthood can be an exciting, yet difficult, time of transition. Individuals in their late teens to mid-20s face unique stressors related to school, jobs, families, and social circles, which can lead to a rise in substance use. Rehab centers with dedicated young adult programs will include activities and amenities that cater to this age group, with an emphasis on specialized counseling, peer socialization, and ongoing aftercare.

Clinical Services

Whether a marriage or other committed relationship, an intimate partnership is one of the most important aspects of a person's life. Drug and alcohol addiction affects both members of a couple in deep and meaningful ways, as does rehab and recovery. Couples therapy and other couples-focused treatment programs are significant parts of exploring triggers of addiction, as well as learning how to build healthy patterns to support ongoing sobriety.

Research clearly demonstrates that recovery is far more successful and sustainable when loved ones like family members participate in rehab and substance abuse treatment. Genetic factors may be at play when it comes to drug and alcohol addiction, as well as mental health issues. Family dynamics often play a critical role in addiction triggers, and if properly educated, family members can be a strong source of support when it comes to rehabilitation.

Group therapy is any therapeutic work that happens in a group (not one-on-one). There are a number of different group therapy modalities, including support groups, experiential therapy, psycho-education, and more. Group therapy involves treatment as well as processing interaction between group members.

In individual therapy, a patient meets one-on-one with a trained psychologist or counselor. Therapy is a pivotal part of effective substance abuse treatment, as it often covers root causes of addiction, including challenges faced by the patient in their social, family, and work/school life.

Welcoming my third child at this hospital has been one of the most beautiful experiences of my life. Having delivered my first two babies at different hospitals, I can confidently say that this one exceeded all my expectations. The nurses, doctors, and staff were exceptionally kind, attentive, and professional, ensuring that every detail of my care was handled with precision and warmth. From the high-quality medical attention to the little comforts that made my stay easier, everything was truly outstanding. Even the food was great, which is rare in a hospital setting! Whether it was medical support or just small gestures of kindness, they were there for my every need, making the experience smooth and memorable. I’m incredibly grateful for their dedication and compassion—it made all the difference.

Worse ER that I have visited. I went with a severe neck, shoulder and arm pain. Was left in the room waiting for the only doctor on duty Matthew Davis, MD. He was rude and rushed me out. I was discharged with naproxen with the same pain that I walk into the ER. Unprofessional and no sympathetic for patients.

What has happened to this hospital? This place used to be the go-to hospital for my family and me for years. We trusted it with our lives—literally. But after a recent experience as a patient, I’m deeply disappointed and frustrated by what it has become since the pandemic. The quality of care has dropped drastically, and it feels like the heart and soul of this hospital is gone. Many of the exceptional doctors we once relied on are no longer there, and it shows. If you need care on a weekend—even for something urgent—be prepared to wait endlessly for tests to be done, let alone reviewed. The lack of access to specialists is shocking. It’s almost like the weekend staff operates on autopilot, doing the bare minimum. The on-call doctors act like being contacted is an inconvenience. Where is the urgency? Where is the compassion? During my stay, I encountered a cardiologist who was not only rude and dismissive, but actually scolded the nursing staff in front of me—for simply trying to advocate for my care. This same doctor showed no bedside manner and treated me as if I were a problem, not a patient. It was upsetting and humiliating. I felt completely disregarded. To make matters worse, communication across the board is abysmal. No one seems to know what’s going on. Test results are delayed, staff members give conflicting information (if they give any at all), and you’re left feeling like you have to fight just to be seen and heard. It’s exhausting. I shouldn’t have to chase down basic information about my health or remind people to follow up. This hospital seriously needs to get its act together. Patients deserve better. We deserve timely care, competent and compassionate providers, and clear communication. It’s heartbreaking to see what this place has become, especially when I know how good it used to be. I miss the days when doctors took time with their patients, listened, and truly cared. Now it just feels cold, disorganized, and indifferent. Please—step up. Fix this. Patients are not just numbers, and we should not be made to feel like burdens for needing care. You can—and should—do better.

I needed immediate medical care , and I’m glad I came to Mountainside hospital. I interfaced with ER physician Dr. Sapira, whose shift was ending and he made sure to seamlessly coordinate my ongoing care with Dr. Avenoso. Dr. Avenoso saw me without delay, quickly ordered the appropriate tests—including a CT scan—and promptly arrived at a clear diagnosis. His decisiveness and clarity were truly reassuring during a stressful time. I also want to express special appreciation for ER nurse Nadira, who was an absolute gem. Her skill, warmth, and attentiveness made all the difference during my ER stay. The ER team worked quickly to involve Dr. Rainville from general surgery, who evaluated me without delay and proceeded with an operation that was both timely and successful. I woke up pain-free in a comfortable room, feeling incredibly well-cared for. Once I was transferred to a room upstairs, Esther, RN, continued that high standard of care. She was attentive, compassionate, and made sure I was comfortable and informed throughout my recovery. From the surgery nurses and ER team to the transport staff, registration, dietary services, nursing, and every physician who crossed my path—thank you. Mountainside Hospital delivered world-class care with heart, and I’ll never forget it.

Just saw a video of how a doctor housed at this location treated a human being because he was different. This facility has doctors with conflicting views about people of color. Be weary of this hospital. Dr Eric Sherman is the doctor. It’s a young lady on TikTok crying her eye out because of the way this doctor treated her father. Please do better.

I had the most traumatizing experience with Dr. Erik Sherman. I brought my father to the ER because he was spitting out large amounts of blood — it was clearly gushing from his mouth. The first thing Dr. Sherman said was, “Well, it couldn’t have been gushing, there’s no blood on his clothes.” He then said he was going to discharge my father without doing any further testing because “he doesn’t look sick.” When I calmly pushed for more testing out of concern for my dad’s health, he told me to “stop yelling” and “stop being loud” — even though I was not yelling at all. I was simply trying to advocate for my father, who doesn’t speak English. Dr. Sherman was arrogant, dismissive, and condescending throughout the entire visit. He showed no compassion or willingness to listen. This hospital used to be my go-to — my sister even gave birth here and I always trusted the care. But after this experience, I will never set foot in that hospital again, and I will make sure others are aware of the kind of treatment we received and the kind of doctor you’ve chosen to keep on staff.

I want to compliment the whole process for my biopsies and mammogram - from the registration team to the breast center team and ultrasound team, everyone is professional and kind. I have had 2 biopsies done by Dr. Chuang, and for one of them Dr. Koh read the mammogram and performed my ultra sound - both doctors are compassionate, professional, and very knowledgeable about breast wellness. The staff worked together as a team. Dr. Koh not only informed me of the results before I left my appointment but he also sent a follow-up in mychart and mailed a copy of the results and the importance of following up to my residence. I will continue to see Dr. Chuang and Dr. Koh for any future testing.

On April 6,2025. I went to emergency Room Dr. Sherman is a wonderful Primary care Physician at Hackensan Medical Center in Montclair, NJ. I see him for a cyst appear it was swollen and painful and he is most caring and very up to date with facts on this type of cyst and he immediatelly take accion to help me. His bedside manner is very tender and caring. He cares very much for his patience and spends the amount of time his patients need. I recommend him highly. Nurse Sheyla, was incredibly helpful and calm throughout the procedure. She explained everything clearly and ensured I was comfortable. One of the best nurse I've ever seen, also I extend my appreciation to the administrative group. Sincerely, Lorena Solis

Beware of fine prints!!! I went to this facility for a Calcium Scoring scan. On their website the price stated even today is $99/-. I called them and specifically asked if that was the only charge as I would be not going through Insurance company but would be paying cash. I was told multiple times Yes that was the only charge. Even at the registration desk I was informed that this is the only charge for the procedure. Subsequently I received another bill from a radiology group. I am told that this is mentioned in one of the fine prints. It would be better to put an asterisk against the $99 on their website with a note about potential additional charges. If I had known about this charge I would have got the test done at a near by facility for less than half the cost.
