MEET DR. SINCLAIR

Driven by a heart for people and a passion for clinical excellence, Dr. Sinclair has saved and shaped smiles for more than two decades.

While working at an ice cream shop during high school, a young Marisela Sinclair met a friend who planned to go to Dental Assistant school. That seemed like the perfect fit for someone like the future Dr. Sinclair, who was known for her big, friendly smile.

Patient Stories

I was pretty nervous about having to get a crown to replace a very old, deep filling. The team at Sinclair smiles did an amazing job of making the experience as soothing and painless as possible. They provided me with ‘Neuro-Calm’ headphones and an eye mask to calm me while in the chair. I was greatly impressed by their speed, accuracy and professionalism. My tooth was 3D scanned with the new one cut via CAD-CAM on the spot! Incredible.

My crown broke off today and stopped by on my bicycle for a consultation with expectations of getting an appointment sometime in the future. Within 15 minutes I was in a chair being pampered and prepped. They were uncomfortable with my bike being outside and brought it into the waiting room for me. Half hour total and I was back on the road with a happy crown, huge smile, and respect for the “team”. Thanks team!

The office is fresh, clean and bright. The entire place seems brand-new with the latest and greatest of everything. The staff is friendly and caring. She seems to keep up with the latest technology and innovations in the industry, always some new instrument she’s trying out. I had Dental anxiety for years prior to meeting Dr. Sinclair, but that has gone away. I tried the NUCALM during my cleaning today, it was relaxing and made the time cut in half.

Dr. Sinclair and team offer a positive dental experience on each visit. I appreciate her honest treatment recommendations, knowing I’m not being bamboozled for extra money with something I don’t need. The office is pristine, comfortable and their work is efficient. They offer flexible scheduling and treat you like a human.

Most gentle dentist I've ever visited. I'm a person who is really afraid of seeing needles, and when I was having work done, I never even saw or felt the injection! Everyone who works there is super attentive and very respectful of any anxieties you might have, and always does their best to make sure you are comfortable at all times. Everyone is also very informed and will make sure you know what you are having done and what you will be paying for at the end of the visit. I will definitely be visiting the office again! Thank you!
