Dr. Greg Allen was born and raised in Michigan where he met his wife Dr. Nadia Bala during the first day of dental school. He is a board-certified pediatric dental specialist and he is one of a handful of pediatric dentists who are qualified to teach Pediatric Dentistry at Rady Children's Hospital, where he has taught for almost a decade.

After dental school, Dr. Greg Allen practiced in San Diego as a general dentist where he discovered his love for pediatric dentistry.

He continued his education by completing a General Practice Residency at St. Barnabas Hospital in New York City. During this residency, he received training in all phases of dentistry including hospital cases under general anesthesia, oral surgery, and rehabilitation of severe trauma cases.

He then went on to complete his Pediatric Dental Residency training at St. Barnabas Hospital where he served as Chief Resident. Dr. Greg Allen received extensive and rigorous training at St. Barnabas Hospital, a Level 1 Trauma Center. He has also received the hospital’s top research award while in residency for his clinical research in public health.
