After changing many dentists, I found the office of Dr. Derek Tang based on a referral a friend made. I have been very happy with my visits and procedures so far. The treatment is focused on the patient and the staff especially is super accomodating, kind and helpful with aspects of scheduling, during the visit and with insurance claims. I am very satisfied with them and look forward to my future visits.

I can't recommend Dr. Derek Tang and his team highly enough. He is incredibly dedicated, caring, and meticulous, always taking the time to make sure every detail of his work is done with the highest level of care. What truly sets this practice apart is the warm, welcoming atmosphere. From the moment you walk in, the entire staff greets you with a smile and treats you with genuine kindness, making you feel right at home. I also appreciate Dr. Tang's honesty and integrity. He never tries to sell unnecessary or expensive treatments or products—he's fair, transparent, and always has his patients' best interests at heart. If you're looking for a dentist you can truly trust, I highly recommend him.

This office is just fantastic! The Doctor and hygienist always treat you well and they never hurt. I moved recently 30 miles further away and I’ll still go to them because they’re that good.

Dr. Tang is always very nice and pleasant, this was my third time seeing him. Twice for cleanings and once for fillings today. It was easy, and as pleasant as it could be. I am happy I found him as my dentist and would recommend him to others!

Had a recent issue with a tooth getting knocked loose and infection had set in. I called dr Tangs office and they got me right in. Dr Tang and his staff are very friendly, professional and made the entire process comfortable and nice. I can’t say enough good things about the experience I highly recommend his practice.

This review was due for sometime. I had not been a patient of Dr. Tang until my unfortunate luck in which I broke my inlay just a day before I had to travel. I was referred to Dr. TANG. Thankfully Dr. Tang was nice enough to see me on his day off, Friday, early morning. I walked in and his front office was very nice and attentive. Dr. Tang immediately had xrays taken and accessed the area. My tooth would now need full coverage, a crown. Dr. Tang explained he could not do the crown at that visit, since I had a plane to catch in a couple of hours, but would place a temporary coverage to hold me off during my trip. Upon my return, I was seen by Dr. Tang and he prepared my tooth for a crown and by my surprise, he had created my crown while I waited comfortable in the exam room. Once he cemented it on, he checked for its integrity. Once finished, Dr. TANG advised me to return for a full exam to avoid any further emergencies. Dr. Tang has extremely calming chair side manners, making it a great dental experience. I've returned for cleanings and his hygienist too was gentle and thorough. Although, Dr. Tang doesn't participate in my insurance, he's worth the pay because I felt he ensures his dental treatment is full of integrity and provides an excellent experience. Thank you Dr. TANG and team! See you soon for a cleaning!

Transferring my care to Dr. Tang was the best decision I could have made. He and his staff are warm, caring, knowledgeable, & efficient. I appreciate all of them. The state of the art technology is a bonus.

I recently had a filling done by Dr. Tang, and I was pleasantly surprised by how smooth and comfortable the entire experience was. Initially, I was a bit anxious, but Dr. Tang's expertise quickly put me at ease. I highly recommend their services! Thank you!
