Dr. Avi completed a General Practice Residency at Jacobi Medical Center, a trauma-one hospital located in the Bronx, NY. While there, he received comprehensive training in oral and maxillofacial surgery, trauma, and treating children with special needs at the famous Rose F. Kennedy Center. He went on to complete his pediatric dental residency at Temple University Hospital in Philadelphia. Prior to moving to Southern California, Dr. Avi was on staff at Jersey Shore Medical Center and served as an adjunct clinical instructor of Pediatric Dentistry at Temple University's Kornberg School of Dentistry.

As a second-generation pediatric dentist, Dr. Avi witnessed the need for better oral care and the importance of prevention through his mother. He firmly believes that every child is unique and that pediatric dentists can make a significant impact on a child's life.

During his free time, Dr. Avi can be found spending time with his wife, Yonit, and their young children Ronen and baby Sefira. He also enjoys skiing, cycling, playing the bagpipes, and exploring Southern California's beautiful parks and beaches.

Get to Know Dr. Thomas Berchtold

Dr. Thomas Berchtold, also known as Dr. B, has been a resident of North County since 2010, living there with his wife and four children. Falling in love with the vibrant culture and warm-hearted people of Encinitas and North County was a swift and natural process for his family.

Embracing a holistic approach to orthodontics, he believes in empowering the body to fulfill its natural functions, intervening with orthodontic treatment when necessary to create an environment for individuals to thrive.

Your First Visit: What to Expect

We understand that visiting a new dentist can feel intimidating, but we are here to help you know what to expect so you can step into your first visit stress-free. When we meet you, we will be focused on getting to know you and your child. If you have a few moments before your appointment, be sure to fill out your new patient forms online! This helps our team prepare and get to know you and your family before we meet you. 

Once you arrive, a member of our team will give you and your child a tour of our office to familiarize you with our space. You’ll also get a chance to say hello to the team and the doctors. But don’t worry, we know that sometimes it takes a while for little ones to warm up to new people. That is why we always take a patient, compassionate approach to our care. We can go at a pace that feels comfortable for you and your kiddo! 

Once we are settled, we will perform a cleaning and exam to get a better picture of your child’s oral health. Finally, we will work together to create a treatment plan that accommodates your needs, lifestyle, and budget. If you have any questions for our team, don’t hesitate to ask away at any time!

Modern Amenities for Exceptional Care

Our office is designed with your comfort in mind. At every touch point, it is our goal for you to feel at home in our care. When you visit us, be sure to enjoy our complimentary beverage station, warm towels, a play area for wiggly little ones, and in-office entertainment. We even have headphones, Netflix, and video games available! 

Beyond these amenities, we also are committed to using only the latest and greatest when it comes to our tools, technology, and services. By using modern dental techniques, we are able to deliver more comfortable, more effective care. This all helps us create positive dental experiences to help you and your family love visiting the dentist!

Giving Back to Encinitas and Beyond

We feel that as providers in this community, it is our duty and honor to go beyond dentistry by getting involved in local nonprofits and organizations whenever possible.
