I was born and raised in Colorado and always knew it’d be back after school–there is no better place than home. I love being outdoors, whether it be skiing, hiking, swimming, playing tennis or golf, and playing with my yellow lab, Huxley.

My fascination with medicine began when I got to hold a human brain in my seventh-grade biology class. However, it wasn’t until I was diagnosed with diabetes that I knew which career path to pursue. The experience made me realize how much care time was spent with Physician Assistants (PAs), and I wanted to follow the same route so I could have significant patient interactions.

Helping others is my passion, and I strive to make patients feel valued, heard, and assisted throughout their care journey.

Dr. Kowalczyk strives to help patients make choices specifically suited to their own health preferences. This means patients feel he understands and addresses their concerns. Dr. Kowalczyk hopes patients leave their appointment with a feeling that he clearly explained their plan of care and that it matches their own personal health goals. This goes beyond the doctor-patient interaction and extends to the full team: nurses, medical assistants, receptionists, schedulers, etc.
