Dr. Daniel O’Callaghan

Hello and thanks for visiting my website! I was born and raised in West Michigan and am thrilled to be able to live and work here. I am married to my high school sweetheart, and we are busy at home with two sons and a daughter.


I attended dental school at Indiana University where I graduated in the top of my class and was inducted into Omicron Kappa Upsilon National Dental Honor Society. Because I have always loved working with children, we moved to Cincinnati immediately after I finished dental school. We lived in Cincinnati for two years while I completed my pediatric dental specialty training at Cincinnati Children’s Hospital Medical Center. I am a proud alumni of Cincinnati Children’s — one of the nation’s top children’s hospitals. While in Cincinnati, I initiated a multi-year process of board certification. I am now a proud diplomate of the American Board of Pediatric Dentistry.

After completing my residency, we moved back to West Michigan where I planned and launched my private practice. I am thrilled to live in West Michigan and look forward to serving your family with empathy, excellence, and integrity.
