Andrew Szatkowski , DC
Born and raised in North Muskegon, Michigan, Dr. Andrew graduated from Life University in 2016 where he earned his Doctorate of Chiropractic.

Wellness is a connection of paths: knowledge and action. I was fortunate to find the wellness path from a very young age. My parents understood how vital Chiropractic care is to healthy growth and development and for this reason, I have experienced the benefits of Chiropractic care my entire life. As a mom, I’m now raising my son Tommy to know what true wellness is, and to understand the benefits of regular chiropractic care for himself. As a result, he is growing up without ‘childhood illnesses’ and rarely ever gets sick. I know that this is because Chiropractic care allows the body to function optimally, as it was intended. There are so many things I love about our practice, but my favorite is how much we value family. We strive to provide affordable, convenient care to people of all ages, so your entire family can experience true wellness.
