About Columbia St. Mary’s Hospital Ozaukee

Columbia St. Mary’s Hospital – Ozaukee is in Mequon, Wisconsin, and is part of Ascension. Ascension is a nonprofit, Catholic healthcare organization with locations in nine states. The hospital offers emergency and specialty care services, including treatment for substance use disorder (SUD) and co-occurring mental health challenges. 

Additionally, they provide treatment for non-substance related addictions, such as shopping, gaming, internet, and gambling. Detox and medication assisted treatment (MAT) are available. The hospital accepts Medicaid, Medicare and most major commercial health insurance and is conveniently located near I-43. 

Addiction Care in Mequon, Wisconsin

The facility is near the shores of Lake Michigan and provides scenic and tranquil views conducive to healing and recovery. Nearby Mequon Nature Preserve has a large green space and more than five miles of hiking and walking trails where individuals can relax and recharge between outpatient treatment sessions. 

Most people think of alcohol or drugs when they think about addiction. But addiction comes in many forms, including problem gambling, shopping, sex and other challenging behaviors. It stood out to me that the programs at this hospital include treatment for many other addictions in addition to substance use disorder (SUD). 

Clinicians address the addiction and underlying mental health disorders contributing to problematic behaviors. There are inpatient and outpatient programs. 

Compassionate and Professional Treatment Environment

Patients have noted the professional, clean environment and attentive and caring staff. Others have highlighted the expertise of the addiction and behavioral health treatment teams. Some clients have expressed their gratitude for the supportive counseling and group therapy. 

The hospital’s campus is modern with a secure behavioral health unit. The inpatient rooms are private or semi private with comfortable group activity and lounge spaces. 

There’s an on site cafeteria and other hospital amenities. I like that you’re in a full service hospital, so any medical needs you may have can be immediately addressed and integrated into your treatment.

Addiction Treatments

Levels of Care

inpatient iconInpatient

Residential treatment programs are those that offer housing and meals in addition to substance abuse treatment. Rehab facilities that offer residential treatment allow patients to focus solely on recovery, in an environment totally separate from their lives. Some rehab centers specialize in short-term residential treatment (a few days to a week or two), while others solely provide treatment on a long-term basis (several weeks to months). Some offer both, and tailor treatment to the patient's individual requirements.

Treatments

Substance rehabs focus on helping individuals recover from substance abuse, including alcohol and drug addiction (both illegal and prescription drugs). They often include the opportunity to engage in both individual as well as group therapy.

Clinical Services

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.

I had an appointment with Dr. Webber, I couldn't have been happier with the staff, or Dr. Webber. I felt very well taken care of and I was very grateful for the help.

Dr. Christopher Weber is my weight management doctor. He provides me with excellent care. Using multiple tools, I have lost about 70 pounds over a couple years. Slow and steady wins the race! Dr. Weber is always kind and supportive, and also encouraging if I’m temporarily frustrated or disappointed with my progress. If I feel I’m just stuck, Dr Weber always has other ideas and tools for me. Thank you, Dr. Weber! (In the second photo, I am on the right.)

The doctors and nurses were excellent! The administrative process, for example, scheduling confirming schedule, determine where to go, etc. Either didn't work or were inefficient.
