I recently moved into the area and needed to find a dentist I felt I could trust. After reading about Medplex I knew that they were a good fit for me given their holistic approach to dentistry. After my first visit, I was BEYOND satisfied with the care and service I was given! Dr. Castellini is a very relaxed and most importantly HONEST practitioner. I am looking forward to giving even greater care to my oral health with the Medplex Dental team behind my back :)

From the moment you check in at the front desk, you can feel the kindness. Maite is excellent and always takes the time to explain paperwork and always makes me feel at ease. She also has a great sense of humor. Nelly, the hygienist has the most gentle smile and also has a gentle touch, so does Susanna the dental assistant. Robert Castellini , the dentist, never makes me feel rushed and has a great personality. I will never go anywhere else as I’ve found my home.

This dentist is amazing! My experience at the office is always pleasant. They’ve been nothing but kind and helpful. I had to get a lot of fillings done and it was all pain free, which I definitely wasn’t expecting. If you need work done on your teeth definitely check this place out.
