Real Healing Starts With Listening — And a Doctor Who Understands the Whole Picture.

At Patterson Integrative Medicine, we believe medicine should feel human — not hurried. Founded by Dr. Karin Patterson, D.O., this practice was created for patients who are seeking alternatives to 10-minute visits, one-size-fits-all treatments, and years of unanswered symptoms. Here, we combine science with soul, helping you uncover the root causes of your health concerns through compassionate, integrative care.

A Board-Certified Family & Functional Medicine Physician
with 20+ Years of Experience

Meet Dr. Karin Patterson, D.O., FAARFM, ABBARM

Dr. Patterson’s educational journey started at the University of Michigan, where she earned her Bachelor of Science with Honors in Neuropsychology and Cognitive Science. Before attending medical school, Karin spent two years working and doing research in a neuroimaging and memory study lab at the University of California, San Diego. After completing her Doctor of Osteopathy (D.O.) degree at Midwestern University in 2003, she pursued her Family Medicine training at MacNeal Hospital in Chicago and became board-certified in 2006.

Following residency, Dr. Patterson began her professional career as a teaching attending in Family Medicine residencies for 3 years at Northwestern University in Evanston and Glenview, IL, MacNeal Hospital in Chicago and St. Vincent's Hospital in Indianapolis. She was awarded teaching faculty of the year during this time. When she and her family relocated to Northwest Indiana in 2009, she became employed by St. Mary Hospital where she successfully built her family medicine practice for the past 16 years.

While practicing primary care and listening to her patients' evolving needs, she pursued training in Integrative and Functional Medicine and started to incorporate these principles into her practice. In 2012, Dr. Patterson completed an advanced fellowship and board certification through the American Academy of Anti-Aging Medicine (A4M), allowing her to go deeper into root-cause care. After 14 years of practicing in this model, she has decided to start a new practice that allows her to focus solely on Functional and Integrative Medicine.

Why She Built This Practice:

Because Great Care Takes Time

“I created this space because patients deserve more. More time, more understanding, more partnership. I do not want just to manage symptoms — I want to help you get to the root cause of illness with our goal being wellness. I believe in shifting from disease based care to true health care.”

— Dr. Karin Patterson
