Our Doctors

Dr. Daniel O'Brien

Dr. Dan O’Brien graduated from the University of Michigan School of Dentistry in 2013, becoming the fifth dentist in four generations of his family to graduate from UofM. He joined his Uncle Jon in practice and was very fortunate to receive his Uncle’s mentorship in the practice of dentistry and is very proud to continue the O’Brien dental legacy in Grand Rapids. When not practicing, he enjoys playing music in multiple local groups and spending time with his wife, Emily, and his two sons, Dick and Leo.  He also has two stinky Newfoundlands, Quinn and Hank.

Dr. Matthew Ellison

Dr. Matt Ellison grew up in Midland, Michigan and went to school at Hope College before beginning dental school at the University of Michigan School of Dentistry, where he and Dr. Dan were roommates. It was here he met his wife, Dr. Barbara Zickgraf.  After graduating and completing an AEGD residency at the University of North Carolina, they moved back to Dr. Barbara’s hometown in the greater Chicago area. Upon learning that his old friend and colleague was looking for a new associate, Dr. Matt threw his hat in the ring and could not be a better fit for the O’Brien practice (although he still hasn’t been talked into changing his name). When not working, Dr. Matt enjoys a new hobby in woodworking, a variety of sports and loves exploring the beauty of West Michigan with his wife Barbara and Rhodesian Ridgeback, Honey.
