Meet the Team

Dr. Sami Kashou, D.D.S.

Dr. Kashou was born and raised in sunny East County San Diego. He earned his undergraduate degree from the University of California, San Diego, with a major in biochemistry and cell biology. During his time at UCSD, he was an active member of the pre-dental society and played a pivotal role in managing the free dental clinic, devoting his evenings to its operations.

Following the completion of his undergraduate studies, Dr. Kashou ventured to Milwaukee, Wisconsin, to attend the Marquette University School of Dentistry, where he obtained his dental degree. After graduating from Marquette, he pursued a General Practice Residency, which he completed as the Chief Resident Dentist in Nashville, Tennessee. This role allowed him to refine his clinical skills and enhance his leadership abilities.

When not practicing dentistry, Dr. Kashou enjoys spending time with his wife Hadil and golfing any chance he gets. He also maintains his professional development by participating in the following  dental organizations, including the American Dental Association, San Diego County Dental Society, and California Dental Association, and the American Academy of Implant Dentistry.

Christina Vosburgh

Treatment Coordinator

My name is Christina and have been in the dental field since 2015. What I enjoy the most about my job is seeing all of our patients! I wouldn’t be able to do what I love, without them. It’s easy to wear a smile to work every day when you really genuinely love what you do!

When I’m not at work, my husband and I love to go to the desert or go to dog beach with our fur baby, who always keeps us busy.
