I truly can’t express how much I appreciate Dr. Renee and Dr. Dean. I started seeing them 7 months ago and they treat me like I’ve been a patient for years. After losing my insurance in the pandemic it had been a few years since I had seen a dentist. Naturally I had one problem tooth that they took a safe a conservative approach with as far as treatment and got me feeling comfortable again.

The friendliness and professionalism of all the staff is exemplary. They are patient and talk through everything with me and answer all my questions. I’ve never been able to say I look forward to going to the dentist, but I love seeing the staff here. I wouldn’t recommend anyone else. I’m so happy I have a dental team I can trust.

I had great expectations when I started . You should always get a second opinion before you have a tooth extracted. That was my mistake. I went to a surgeon to get a second opinion. I had no idea when my bridge was put back in my mouth that was glued back . Great repair work.

I was in excruciating pain and didn’t know where to turn. I started a general search for a dentist in my area and began reading reviews. Boy, am I glad I did. I had never met Dr. Glasser before, but he squeezed me in for an emergency root canal that same day — something I’ll never forget. He didn’t have to, but he went out of his way to help someone in real pain who wasn’t even his patient yet. That kind of compassion and dedication is incredibly rare. From the moment I walked into the office, I felt at ease. Dr. Glasser was gentle, thorough, and completely upfront about everything.

He explained the procedure clearly and made sure I felt safe and comfortable the entire time. Later, I had a tooth extraction, and again, the level of care was incredible — no pain, clear aftercare instructions (including a helpful video), and a genuine sense that I was being looked after, not just treated. Dr. Renee is just as exceptional. She brings the same warmth, professionalism, and compassion that makes this practice so unique. Together, they’ve created an environment that truly puts patients first. The entire staff deserves praise too. Everyone I interacted with was friendly, considerate, and truly kind. This doesn’t feel like a business — it feels like a practice built on integrity, compassion, and a real commitment to helping people. They also understand that dental work can be expensive and stressful.

They’re fair, transparent, and never make you feel like money comes before your well-being. For the level of skill and care they provide, that means everything. Honestly, I never thought I’d say this, but I actually look forward to going to the dentist now. Dr. Glasser, Dr. Renee, and their amazing team are the real deal. I’m writing this because people like them deserve to be recognized. I’d recommend them again and again — without hesitation.
