Dr. Greiner is a Southern California native having grown up in Huntington Beach. He attended UCLA for his undergraduate studies graduating with a degree in Computational and Systems Biology. He then left sunny California and attended Boston University for Dental School. Surviving 4 long New England winters allowed him to receive a Doctor of Dental Medicine. During his time at Boston University he was on the Naval Health Professionals Scholarship Program.

Upon completion of his dental degree, Dr. Greiner was stationed at Camp Pendleton to complete an Advanced Education in General Dentistry residency. During this time, he developed a passion for Endodontics. Following Camp Pendleton, Dr. Greiner went on to Endodontics residency at the Naval Postgraduate Dental School in Bethesda, MD. Upon completion of the program he received a Master’s in Oral Biology and a certificate in Endodontics. Shortly after residency he completed all the necessary requirements to become a Diplomate of the American Board of Endodontics. From there he spent two years in Okinawa, Japan as an Endodontist for 3rd Dental Battalion before returning to Camp Pendleton. He is very happy to be back in the greater San Diego area and is looking forward to serving the community!

Dr. Greiner lives in Carlsbad with his wife, Rachel, and his son, Graham. He is a huge Lakers and UCLA Bruins fan. Any chance he gets he likes to spend his time on the golf course. He enjoys any activity that gets him outside in the beautiful San Diego weather.
