I highly recommend anyone with little kids to come here they truly care about their wellbeing and how they feel about the dentist. The way Dr. Tajik treats my kids really helps them feel comfortable coming back to their appointments. Thank you Total Care for taking care of my family and myself.”
“Brought my daughter in for braces, and this was our first visit here. When I originally called, the scheduler accidentally booked us for regular dentistry instead of orthodontics, but thankfully Tina stepped in and quickly resolved the mix-up. She made sure everything was taken care of, and her professionalism and kindness really stood out—she’s definitely an asset to this office. The office itself is spacious, spotless, and welcoming, and the entire staff is friendly and helpful.”
