Dr. Jason Lauf DO

"I was born and raised in Lima, OH where I spent most of my time at my grandparents farm that helped instill my desire to help others in a rural area. I then attended The Ohio State University in Columbus and graduated with a biomedical engineering degree. I then decided to pursue medical school at Ohio University Heritage College of Osteopathic Medicine in Dublin, OH. From there, I decided on Internal Medicine and pursued residency at University Hospital Parma Medical Center. Now, I am looking forward to treating patients in the greater Marion area. Recently married in 2022 and the family now resides in Richwood, OH. We are very much looking forward to helping care for members of our community." ~ Dr. Lauf
