You never feel rushed or uncertain; instead, you feel genuinely cared for and confident in his expertise.

What really sets this office apart is the compassion and attentiveness. It’s clear that Dr. Hewlett truly cares about his patients and their well-being.

The office staff are just as incredible—welcoming, professional, and consistently kind. A special thank you to Deana at the front desk, who treats every patient with such warmth,… read full review

I can't say enough positive things about this office. To say I had extreme anxiety is putting it mildly. They were so patient and accomodating to meet my needs and fears. Dr. Hewlett has a very calm demeanor that puts you at ease and Deanna is the best. I have pestered her with emails and phone calls and she has answered each question I've had with friendliness and knowledge and patience. You will not regret your decision if you ever choose this office for your dental needs.
