My husband and I both had appointments with the dental hygienist in December. BethAnne was our go to young lady for our visits. She was polite, professional, and very thorough. She gave my husband and I suggestions on ways to improve our dental health. She was fantastic. The office is following Covid guidelines, using technology to effectively communicate with us prior to our appointment and upon arrival (text ,email and phone). The front desk staff were friendly and welcoming. We’re lucky to be patients with Dr. Thomaszadeh office.

I had a great experience at my first visit and highly recommend Dr. Thomaszadeh and her staff. They were very friendly and efficient. I was seen on time and out in under 30 minutes. Dr. Thomaszadeh had big shoes to fill after my life long dentist Dr. Romanelli retired, but she met the challenge and I am glad to have a stellar new dentist.

The visit was great. 1. It was on time. I hate waiting so this is important. 2. The texts that I received before my appointment were helpful in reminding me of my date and time. 3. I felt very comfortable with all the precautions they took for the covid19. The online questionnaire was easy and to the point and I was able to fill it out prior to my appointment. I felt safe by the actions they took in the office too. They had air purifiers, hand sanitizer and the staff was decked out in the appropriate attire. I highly recommend Dr. Thomaszadeh and her staff. Beth, who cleaned my teeth was great too.

Dr. Thomaszadeh Office is friendly and you immediately feel the staff’s competence. For my most recent visit, they were able to consolidate and address several issues In one visit. I appreciate the single office visit vs two visits. I transitioned from the previous doctor to Dr. Thomaszadeh this past year. The transition has been smooth as I was immediately impressed with the doctor’s willingness to answer all my questions and an efficient chair-side manner. This office is great!
