Eric Kreckman, PA-C

Eric has a Bachelor of Science degree from the University of Michigan and his Masters in Physician Assistant Studies from Central Michigan University. Most recently he practiced family medicine in Gladwin. He has 2 children. A daughter who graduated from the University of Michigan in 2015 and a son who graduated from Michigan State University in 2016. 

Eric says, "While at times I was at my wit's end, I loved raising my children. The initial fear, the sleep deprived days, the frustration, the mess, the tears, the joys and elations. . . I miss it every single day. It's not an easy job for parents. Share your struggles and your concerns and we will work through them together."

He has a particular interest in early screening and preventative measures and feels he has the distinct privilege to help set in motion habits that will not only lead to longer lives but HEALTHIER, FULLER, HAPPIER lives.
