He completed his undergraduate studies at the University of California Irvine, where he studied biological sciences and graduated with excellence in research honors. He then worked in biomedical research for a year before completing his master’s degree in global medicine at the Keck School of Medicine at the University of Southern California. Dr. O’Donnell remained in Los Angeles to complete both his dental school training and his pediatric dental residency at the University of Southern California. During his residency, he spent the majority of his hospital training at the Miller Children’s Hospital in Long Beach, where he had the opportunity to treat and manage multi-disciplinary cases for children with various medical conditions. He was also able to serve on multiple hematology-oncology subspecialty clinical teams and was a member of the craniofacial clinical team.

This can have a profound impact on our lives, especially those of children.

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.
