I visited the doctor Trent westernoff yesterday and was thoroughly impressed with the exceptional customer service I received. His friendly demeanor and positive attitude made the entire experience comfortable and pleasant. He took the time to explain procedures, ensuring that I felt at ease throughout my visit. It's clear that he genuinely cares about his patients, and I truly appreciate the attention and professionalism

I don’t think that I can give enough accolades about this group. Everyone was efficient, caring, accommodating. Absolutely professional. My son and I received the best of care. I brought my son in for oral surgery and I was also scheduled for a consultation regarding the same kind of surgery while his was taking place. I was expecting to need scheduling at a later time, but they were able to accommodate me for surgery today. This made me happy, especially since I was suffering from so much pain.My son is autistic and can have a lot of anxiety when in public places. They took everything in stride to help become calm.through the process.As for myself. I was a bit nervous because of not so great past dental experiences. I also have a tendency to be difficult to anesthetize. Dr. Westernoff was very patient and did not give up until I couldn’t feel a thing. The procedure itself went very quickly!
