Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Strongly recommend.
My teeth were thining & discolored. Dr. Lacosse advised me of my options. He successfully crowned my front teeth & made sure I was happy with my results. My teeth health is very promising as long as I brush & floss.Also checkup every 6 months.I am happy with the service he & his staff provide.

I have been so totally pleased with Dr. Lacosse and his staff. From the help at the front desk, to my cleaning appointment and now with restorative procedures....Dr. Lacosse's office has made this a very comfortable experience. We were able to complete all of the needed restorations with minimal discomfort on my part, and considering the difficulty I have with dental procedures, this was a HUGE bonus. I will most definitely recommend Dr. Lacosse and his staff to my friends and family.

Dr Lacosse... you have an amazing dentistry and great staff. I've had good dentists over the years, but this was the most impressive experience Ive had. I got a new crown and had an old filling replaced. Painless and perfection. Thank you

Impressive facility with parking right outside the front door, state of the art equipment, thorough exam, and friendly and patient staff as we figured out insurance and out of pocket costs. Very impressed! Will be returning for a crown on a broken tooth that is only going to take one day (1.5 hr.) to complete!

Dr Lacosse is a very down-to-earth, friendly dentist who immediately makes you feel comfortable no matter what dental problem you present him with. I immediately felt comfortable with him even though this was my first visit with him. I would highly recommend him to family and friends.
