Dr. Stephan Barrington

Dear patients,

I would like to take this opportunity to announce the addition of Dr. Stephan Barrington to our team. I am extremely pleased to have the opportunity to invite him into our office beginning in August 2021. During the last 4 years, Dr. Barrington has been serving our nation's military as a Lieutenant in the Navy Dental Corp. Dr. Stephan Barrington, having completed his obligation to the US Navy, has finally settled down in the San Diego area. He is accompanied by his wife, Evagelia, and their three young children Louka, Zoi, and Kassiani.

Dr. Barrington grew up in Lodi, California, received his undergraduate degree in Biology and then proceeded to earn his Doctor of Dental Surgery from Loma Linda University in 2017. He excelled in collegiate athletics in both water polo and baseball. He was recognized by his faculty for maintaining Dean's List throughout his whole dental school education.

I had the joy of meeting Dr. Barrington during his time, here in San Diego, while he was at Camp Pendleton. We built a relationship and I found that Dr. Barrington is a person of high integrity and strong core values. Dr. Barrington and I mirror each other's practice philosophy, treatment goals, and endeavor to support our team with focused dedication toward our wonderful patients. He has expounded his skillset across many different facets of dentistry and is committed to providing his patients with optimal comprehensive care. In addition, with Dr. Barrington's contribution, our office will provide expanded services and offer additional flexible hours. I know he is eager to meet all of our patients and I have the utmost confidence in his ability to take care of your dental health. Welcome home Dr. Barrington!
