Dr. Pham is an amazing dentist and Lumi Dental as a whole were very professional. They were very accommodating to my schedule and we're great with communication through email, text, and phone calls. Dr. Pham was very clear and detailed in explaining the work that was being done. Would 100% recommend Lumi Dental Studio to everyone.

I historically am very uncomfortable getting any dental work done including cleanings. Dr. Pham has really helped me overcome my anxiety and fears. Their office is easy to get to and easy to park. Communication: They are easily reachable by phone and text. Appointment reminders are great and a care plan is sent for your review before scheduling so you can pick/choose what care you want. Plus it gives time to ask any questions. Care: In the past year I've had 1 root canal, 2 cavities, and 2 cleanings, and repaired chipped teeth. I am in a lot less pain and and procedures all went smoothly. Their whole team is always checking in with me if I am okay or experiencing any pain/discomfort. Endodontist I was referred to by Dr. Pham did a great job and the permanent crown had an excellent fit. Teeth Cleaning: Dr. Pham performs my cleanings and there is very little pain as opposed to other experiences where I would have very sore gums. Financial Considerations: Our insurance was accepted and their office does a good job to work through what is covered and what isn't. She also has a membership program that I think is more for uninsured/under insured. Scheduling: I have had every appointment accommodate my work schedule either in the morning or the afternoons. It motivates me to make sure I reschedule early if needed since it is so easy.

I don’t usually like going to the dentist, but everyone here is very professional, friendly, and willing to accommodate you every step of the way. They aren’t pushy with treatment or judgmental either. Just got work done today and Dr Pham and her assistant were so kind. 10/10 recommend.

I moved to the area in June 2023 and needed to find a new dentist. I searched for a dentist who was honest and wasn't going to charge me for services that I didn't need. Dr. Pham was extremely thorough on cleanings and dental work. She identified early cavities (that my previous dentists didn't treat), and the whole process of getting fillings was so easy. She showed me before/after pictures which put my mind at ease knowing that Dr. Pham is a very honest and experienced/capable dentist.
