Dr. Tarek Kassem

Just Laughs, Just Smiles, Just Kids!

Dr. Tarek Kassem

DDS

Location: San Leandro & Tracy

I am thrilled to join the Just Kids Pediatric Dentistry team and honored to be entrusted with your child’s oral health. I was born and raised in Southern California and moved to the Bay Area to be with my wife. I am incredibly excited to call the Bay Area my new home. I received my undergraduate degree in Biochemistry at the University of California, Los Angeles. I went on to complete both dental school and a twenty-five-month residency program in Pediatric Dentistry at the University of California, Los Angeles, School of Dentistry.

As a Pediatric Dental Specialist I am trained to provide your child with truly excellent dental care. I am deeply committed to giving your child the best experience possible.

Outside of dentistry, I spend the majority of my spare time with my wife and family, exploring the outdoors, and trying new cuisines.

I am a member of the American Dental Association, California Dental Association, American Association of Pediatric Dentistry, and California Society of Pediatric Dentistry.

Amazing amazing amazing. This place knows how to welcome kids in and make them feel like it's their space. Not easy to do that for a dentist's office. I'm so impressed and we'll definitely be coming back regularly.

We have been using the services of this kids dental clinic for three years now. I trust the staff as much as myself. I really like the approach to children. Clear advice, always clean and tidy. Goodwill, honesty, transparency and decency are the most important qualities that I have seen during this time. And this is not unimportant. Thank you for healthy teeth and happy smiles
Response from the owner:Hi Svitlana! We're so incredibly happy to know that you've always had an amazing experience with us. Thank you for this feedback and for being with us for 3 years now. See you in your next visit!
Deborah C.
Dr. Chang and his staff have been amazing since day one. My oldest daughter walks in like a champ, knows the routine, and understands that everyone there wants to take care of her. My younger one is the tougher patient but the staff works hard to calm my kid’s nerves and knows how to work efficiently with my firecracker of a daughter. So thankful for Just Kids Pediatrics Dentistry and the positive experiences we always have here.
Response from the owner:Thank you, Deborah! We’re thrilled to hear about your positive experiences with our team. Supporting your daughters’ comfort and confidence is our priority. We appreciate your trust in us!

Donovan C.
What a great facility and team! From the moment you walk in the staff makes it all about making your kids feel seen and excited! Comfortable waiting room with movies for the kids, very clean and neat. This was my son’s first dentist visit and he expressed to me that he was nervous, but the team at Just Kids made him feel very comfortable! Dr. Jonathan Chang and his dental hygienist did amazing work talking through the services they will be doing. He listened to my questions and concerns as he addressed and reassured me everything was great! Best part of all NO CAVITIES!!!!

Thank you Just Kids Pediatric Dentistry!
Will definitely refer all my family and friends to your facilities!!
