Dr. Samuel Russom

Pediatric Dentist

Dr. Samuel Russom, known to his patients as Dr. Sam, believes strongly that communication is the cornerstone to being a great pediatric dentist. “During procedures, I like to tell patients and parents what I am doing, as well as why I’m doing it. I find this helps patients and their parents to accept treatment and be an active participant in their oral healthcare,” said Dr. Sam. He also brings a light-hearted attitude to the office and enjoys making patients and parents laugh during visits.

Putting children at ease and alleviating their fear of going to the dentist is one of Dr. Sam’s top priorities, as he recognizes the importance of establishing good oral healthcare habits early on in life. “Recently, I had a patient with severe dental anxiety come to me in pain. She had to get through multiple visits and at the end of her treatment, she told me, ‘You’re the best dentist ever because I never feel anything.’ That’s what makes it all worth it,” said Dr. Sam.

Collaboration with colleagues is also an important part of Dr. Sam’s treatment philosophy. He is a member of the American Dental Association (ADA), the California Dental Association (CDA) and the San Diego Dental Society. Dr. Sam is also proud to have been inducted into the Omicron Kappa Upsilon National Dental Honor Society and to have provided care to an underserved community at the Southern Indian Health Center in Alpine.

Dr. Sam earned a BA in Biology from San Diego State University and went on to the UCSF School of Dentistry, where he received his DDS degree. From there, he returned to Southern California and completed his pediatric residency at the University of Southern California. “I was a resident at Children’s Hospital Los Angeles where I treated medically compromised and developmentally delayed children,” explained Dr. Sam, who takes great pride in his experience treating children with special needs.

A native San Diegan, Dr. Sam was born and raised in Southeast San Diego. His parents came to the U.S. as refugees, and he is the first of his family to graduate from college. He has an older sister and a younger brother, and is very close to his two nieces. In fact, much of his free time is spent babysitting! A self-described nerd, Dr. Sam loves going to coffee shops to read science fiction and fantasy novels, as well as comics. He also enjoys basketball, volleyball, and hiking.

Dr. Bernard Boback


Dr. Bernard Boback, or Dr. Bernie as he is called by patients, is a UCLA and Harvard educated orthodontist who is proud to transform the smiles – and the lives – of his patients. “The best part of my job is seeing the confidence that comes from a transformed smile. Every day, I have the opportunity to see my patients, who previously were hesitant to smile, beaming across the room. Not many people can say that about their profession,” said Dr. Bernie.

When patients come to see Dr. Bernie, they are immediately put at ease by his friendly demeanor and extensive knowledge of orthodontics. Dr. Bernie views every case as an opportunity to learn and grow within his profession, and works with each patient to provide the best possible outcome. He is focused on keeping his patients motivated throughout their treatments and considers them to be integral parts of his team. 

Working closely with other orthodontists, as well as with colleagues in general and specialty dentistry, is also an important component of Dr. Bernie’s philosophy. “I belong to both the American Association of Orthodontics and the American Dental Association and the networks of professionals within these organizations are fantastic resources. Collaboration and the sharing of resources are critical parts of ensuring that all my patients receive the best possible care and the best treatment plans for their unique case,” explained Dr. Bernie, who is an Invisalign Certified Doctor and has experience with the most up-to-date and innovative orthodontic technologies. 

Dr. Bernie grew up in northeastern Pennsylvania and attended the Honors College at the University of Pittsburgh, where he graduated Magna Cum Laude. He then went on to graduate from Harvard University School of Dental Medicine, winning the Grace Milliken Award for Best Thesis in the class of 2014. Moving from Boston to the warmer weather of Southern California, Dr. Bernie attended the UCLA School of Dentistry, where he completed his residency and earned his certificate in Orthodontics and a MS in Oral Biology. Dr. Bernie stayed in Southern California after completing his residency and is happy to have settled in San Diego. 

When he is not seeing patients, Dr. Bernie can be found restoring classic automobiles and spending time with his wife and two dogs. “Restoring classic cars is a passion of mine that I’ve had since I would work on cars with my dad. I love taking something with a lot of potential and creating something amazing. It’s fun, challenging and rewarding,” said Dr. Bernie, drawing a distinct parallel between his chosen profession and his beloved pastime.
