About Us
Guiding You to Resilience
At Bay Psychiatry™ of Wisconsin, we believe mental health care should be as human, compassionate, and collaborative as it is clinical. Founded by Kari Mahlik, MSN, NP our practice was created to expand access to high-quality psychiatric care in a setting that feels safe, supportive, and deeply personal.
​
We provide comprehensive mental health services across the lifespan, from psychiatric evaluations and medication management to therapy and second opinions, blending both holistic and western medicine to meet your unique needs.
​
Our approach is centered around you, your story, your goals, your pace. We’re here to walk alongside you, not in front of you, offering guidance and care as you navigate life’s challenges.
