John Abdelmessih DDS: A Lifetime of Commitment

General Dentist

Dr. John completed his undergraduate studies at the University of Detroit where he majored in Biology.

He also spent time in the Learning Center tutoring students struggling in Biology and Chemistry. During college Dr. John worked at Henry Ford Hospital in Detroit as a Dialysis Technician.

He then went on to earn his Doctorate of Dental Surgery degree from the University Of Detroit Mercy School Of Dentistry. He graduated in 1999 and has been in practice ever since.

Dr. John has worked in Southeast Michigan for his entire career and in 2005 fulfilled his lifelong dream of opening his own dental practice. He started Crestwood Dental Group in Clarkston so he could serve the patients in his community.

He has taken extensive continuing education courses throughout the country with a keen focus on pediatric dentistry, oral surgery, and Implant Dentistry. He has earned a Fellowship with the International Dental Implant Association.

In his free time Dr. John is an avid boater and enjoys skiing and camping with his family. He is an active member of his church community and volunteers his time at his children’s school. Dr. John prides himself on offering compassionate, affordable, quality dental care to all of his patients.
