I went for an initial visit, cleaning and consultation after 5 years of no dental exams. Dr. Marianna Rexan proved that she is very caring and concerned about giving her patients the best care possible. She phoned me directly to offer a longer appointment time than initially scheduled. Being my first office visit and several years since any dental work, I was happy to receive the longer consultation.

My appointment began with some quick paperwork followed with receiving a full set of x-rays. Next, Dr Rexen met me and we went over all concerns that I had with my teeth and gums. She then reviewed my x-rays and performed a full oral screening and exam. Afterwards, we discussed three teeth in need of either fillings or restorative work. We scheduled a convenient followup date to perform that much needed work, and to reexamine a gum blemish she noted.

Very reassuring was Dr Rexen's focus on preserving as much natural tooth as possible when removing carries, thus improving chances that restoration will completely resolve tooth sensitivity.

Next minute was my visit with Ruth, the resident dental hygienist. Ruth's tool handling skills are superb.She is gentle, yet thorough. My gums were given the full probing for pocket depth along the roots. The whole time she checked there was no discomfort as she has a great talent of knowing where the pocket ends. Her ultrasonic cleaner and hand tools eliminated 5 years of tooth tarter and calculus in short order. Then she polished the teeth leaving them smooth and looking and feeling great.

During my appointment with Ruth, we discussed the need for a deep cleaning or root planing. Not knowing what my insurance covered, Hannah, their receptionist, checked my insurance carrier to give me the answer..

That this office deals directly with the insurance carriers is another great plus. So, when your treatment is covered you don't have to pay full price upfront and claim the reimbursement from your insurer. This substantially eases any expense..

Dr Marianna Rexen and her entire office staff was a pleasure to meet and be with. I would recommend Dr Rexen's dental practice to everybody.

The front desk was rude

Never took the times I had ask for

Into consideration yes I missed my appointment

But I had asked multiple times to be the last appointment of the

Day the front desk clearly ignored that and when I asked to

Have my records transferred she did not even make an effort

Try and keep me as a patient she was like okay

I DO NOT support negative vibes like this because we as patients are the ones who make the practice not the staff and the rude attitude that makes patients leave

I had a wonderful experience here. I had to switch dentists due to my previous dentist retiring and Marianna is amazing. She has a wonderful calming presence and very thorough. The whole office staff is very nice. I am so glad that I found her!!

Absolutely first rate. Dr. Rexan and staff were ready for me at the appointed time, and proceeded diligently with latest available technology to attend to my needs.

I have scheduled a cleaning, x-ray, and dentist review. In the middle of the cleaning the dentist said she has to leave and I will have to come back some other time so that she can review my x-rays and do a physical examination of the teeth. Commuting to the clinic takes 1 hour each way for me and all other clinics I visited always were able to do it all in one visit so not great job with scheduling my appointment.
