Sheryl's Success Story

I am Cheryl  and I’ve been going to Lifetime Smiles for 4 years and I would totally recommend it to anyone who is looking for a fabulous dentist. When you go in here it’s like coming to a spa,  and you’re pampered, and you know,  you feel at ease. There’s no pain. It just feels great and the people who work here are so nice. And they talk you through every step of the way, everything that they’re doing. It’s very clean, and that’s a really big thing for me. I absolutely love this dental practice, absolutely! I just think it’s .. I’m so happy that I found them, and my son comes here, and I recommend it to all my friends and family. And I just think that if anybody – if you come here you’ll just really, really enjoy it, and you’ll love the results.

Brandon's Success Story

Hi I’m Brent Kenaston.  My family and I have been coming to the dentist here at lap times miles for about two years, and never in my life have I actually looked forward to going to the dentist. But with whiter smiles, I actually really look forward to my appointments. They have my favorite television show that I can watch while I’m in the chair. I enjoy catching up with everybody that works here. I really, really, look forward to coming here, and my kids for the first time ever are super excited about coming to the dentist. They about it, so it’s like nothing I’ve ever experienced before.

Elise's Success Story

Hi I’m Lisa Curtis. I have been coming here for a little over a year. Due to a situation that didn’t go so well for me I came in not knowing this doctor at all, and she completely took me in and fixed the problem I was having. I can’t even tell you how much she went out of her way to help me. And my family will be coming here as well, and I highly recommend this place. If I moved to Florida, I might make the trip back to continue coming to this place. And I have nothing to say other than this place has been welcoming – the staff, every single person is kind, friendly – I never feel rushed. The front desk is above and beyond! I just am so grateful I found this place.
