Staff was fast and friendly, office was clean and tastefully decorated. Dr.Thomaszadeh was very thorough, one of the most thorough oral exams I’ve had, and easy to talk with. Working in the medical field myself these are all attributes of a well organized and run office. I’m looking forward to continuing my dental care with Dr Thomaszadeh’s team.
Had a filling fall out and they got me in the next day after I called. No waiting at all at office. Went right in and Dr T took care of it right away. Was as good as new in 25 min. Absolutely top notch care by Dr T and her entire staff. Could not be happier.😁
Dr. Thomaszadeh and her staff are the best! We had been with Dr. Romanelli for almost 10 years before he retired and we couldn't have lucked out any more with her taking over his practice. We've been treated by her and her professional, amazing staff for many years now, with all levels of dental needs, and they never disappoint. So grateful for Dr. T, Beth Ann, Marissa, and the rest of her team!
Dr.Thomaszadeh is amazing, patient, and gentle ! I used to see her at another office, and was thrilled to find her again. All the staff is wonderful. From the front office Marissa is kind and helpful. The dental hygienist is very gentle as well. Also, all the staff and assistants are sweet and gentle too. If you have any anxiety about the dentist, then this is the place to come. They will make you feel very comfortable and welcome.
Absolutely the best dentist I've ever been to!! Dr. Thomaszadeh is very nice, personable, knowledgeable, and skilled. Her office staff is kind and helpful. The dental hygienists in this office are also the best I've ever encountered. They're very detailed in their work and highly skilled at cleaning mouths with braces/orthodontic appliances as well. 10/10 would recommend over and over again.
