Alex Finck

Born and raised in Mexico, Missouri, I always knew I was going to return to practice medicine and care for the people here. My wife, Loren, is a Mexico native as well, so we both know from experience how wonderful a place Mexico is to live and raise a family. We are excited to finally come home and help care for the community that has always been home to us. 

I chose family medicine because I enjoy the variety of care I can offer to my patients. I like getting to know my patients and their families and being “their doctor”. I want to care for all ages and all varieties of common medical conditions.

Having grown up in the small town of Festus, Missouri, providing care in a rural community has always been my goal.

I chose family medicine for two main reasons. First, I believe that a core problem with our current healthcare system is the limited access to primary care. 

Second, family medicine allows me to see patients of all ages who have a wide variety of health care needs. Every day is different.

When not working, my wife, Sara, and I enjoy being outdoors and exploring trails with our dogs. We look forward to making Mexico our home.
