About Dr. Marcus


Dr. Marcus was born and raised in Connecticut.   At the age of 25, he earned his DMD degree in 1993 at The University of Connecticut School of Dental Medicine.  After graduation, Dr. Marcus was honored to be one of only three dentists selected from hundreds of applicants to join the Post-Doctoral General Practice Residency at the VA Medical Center in La Jolla.  He entered private practice thereafter and has served thousands of patients since.

Dr. Marcus retired from clinical practice in 2019.  He will be focusing on dental education in the future.
