Aisha is such an awesome representative of this fine dental group, my daughter is five and before her last two visits we could never complete a check-up. Well two checkups later and my daughter is so comfortable having no problems with visiting the dentist. You guys are awesome and Aisha is to be commended.

My daughter(Kiki) & I have been going to Sierra Lakes since we moved back from Texas in January 2025. This is by far my favorite dentist office to go. They have done a tremendous job for Kiki's braces and her cleanings! Raychel is just amazing! She is so kind and comforting when we arrive, she knows who we are which makes the experience much better. Love to say this is our dental home!

I’ve been going to this dental office for the past 17 years, and I’ve had Dr. Schmidt for as long as I can remember. There’s a reason I keep coming back, this place truly feels like home. From start to finish, everyone here is amazing. Even the gentleman who took my x-rays was kind, professional, and made the experience smooth and comfortable. The entire team is so welcoming and hospitable, and you can tell they genuinely care about their patients. Shelley is incredible!! She always makes me laugh and brings such a warm, personable energy to every visit. I genuinely look forward to catching up with her about our lives every time I come in. Over the years, we’ve built such a strong rapport, it honestly feels like seeing an old friend. We know so much about each other now, and that kind of connection is so rare to find, especially in a dental setting. Both she and Dr. Schmidt have created an environment where I feel completely at ease. They’re also very accommodating to my needs, which I truly appreciate. I might be one of the few people who actually enjoys going to the dentist, and it’s because of this team. I always leave feeling refreshed, taken care of, and in a better mood than when I arrived. I genuinely look forward to seeing them and catching up each visit. Highly recommend!

What is the Mouth-Body Connection® ?


The Mouth-Body Connection® refers to the link between oral health and overall health, and the role that the harmful bacteria and inflammation in our mouths play in chronic, systemic disease. That’s why it’s time we talked about more than your teeth. Our office prioritizes your overall health as it relates to your oral health. When we care for your smile we’re also looking out for your entire self.
