Warning. If anyone looking for an office to have your dental work done. Please consider my experience with them. I came in for an emergency appointment, got x-rays , diagnosed by the dentist, paid my bill and schedule to come back for treatment. I was giving an estimate of $1200-$1400 to have the work done. Time to pay the bill, it was close to $2200. I was shocked and disappointed, I did not gave consent for a treatment this much but sadly paid the entire bill anyway. If I knew it would cost me this much to have the work done. I would of had chosen other options. The next day, I called the office

Dr. Gus is an amazing orthodontist that helped to align my teeth. Dr. Andrea added filling material to shape and lengthening my upper front teeth. Both dentists worked together to improve my smile and overall I'm 100% satisfied!

Dr. Gus, Dr. Sunita are the best. In the last 6 years, they both helped my husband and I improve our dental health. They're both very gentle and genuine. Their hygienist are also amazing, very gentle and thorough. Sadly I have to move to another dental clinic for personal reasons, but thankful for these doctors and their hygienist.

I had neglected my teeth for a couple of years and needed some work. Dr. Waleed took good care of me with no complications or pain. Thank for being great at what you do! I highly suggest seeing him for all your dental needs.

I have been going to this clinic for over 15 years specifically to see Dr. Nick! He is the best dentist i have dealt with. Unfortunately, he retired and there was change of management. I am extremely disappointed with the new team specially the billing department. After my last visit they asked me to pay for an outstanding balance that my insurance didn't cover from 3 years ago! I have visited the clinic multiple times, as I am a regular patient there, and during the 3 years not once did they mention that the insurance didn't cover it. When I questioned that its been 3 years and this is the first

I absolutely love this clinic. All of the receptionists are friendly and want to help; Especially sorting out insurance :/ ! I see Dr Sunita and she is the kindest most caring dentist Ive ever been to! Very knowledgeable and genuinely cares about my health! My hygienist Sandra is VERY detailed and a pleasure to see for cleanings. I look forward to them! Look how clean my teeth are !!!
