Dr. Ducastel received his medical degree from the Michigan State University College of Human Medicine. He completed his internal medicine internship and residency as well as Nephrology fellowship from The Ohio State University, where he held the position of Chief Fellow.

“I knew I wanted to go into medicine when I was studying biology at the University of Michigan,” said Dr. Ducastel. “From there, nephrology was a clear choice.”

When looking for a location to practice medicine, Dr. Ducastel knew he wanted to come back to his hometown of Petoskey. “After my one month internal medicine rotation in Petoskey, it was my goal to return home to Petoskey and practice medicine.” stated Dr. Ducastel. “Growing up in northern Michigan, you sometimes forget how amazing this place is. I am looking forward to being close to my friends and family, and soaking in the beautiful bay views.”

Back in Petoskey, Dr. Ducastel is excited to spend more time with family and friends as well as introduce his wife Natalie and two French Bulldogs, Gus and Penny, to all that northern Michigan has to offer.
