Patient Testimonials

Dr. Kat and the entire staff at Smith & Heymann are wonderful! Dr. Kat has done a great job straightening my teeth. If I ever have any questions about my treatment plan she makes sure to take the time to answer each one thoroughly and she does so with genuine kindness. I can't recommend this practice enough!

Dr. Smith is amazing with kids. My first time here. It is one of the most advanced dental clinics I have ever seen. Self-check-in and I was called in on time. Attention to detail by Dr. Smith and all the staff. Super friendly staff.
- Hamayun

Dr. Smith and his staff are the kindest people! They really care about you and your smile. I could not have asked for a better team to not only assist me with my braces but also two jaw surgeries. I will be going back to them when my children need braces. Thank you!
- Jessica

Both my wife and I have used Dr. Smith for Invisalign. Both of us started our experience with another provider. Dr. Smith has the smoothest running, kindest, and most capable ortho practice I've ever worked with.
- Andrew

Best dental experience ever. I enjoyed every visit to Dr. Heymann and am thrilled with my treatment results! Several people recommended him (including my favorite dental hygienist, who was herself a patient of his) for Invisalign straightening.
- Kathryn

Dr. Smith is an excellent orthodontist; my spouse is a dentist, and she trusts Dr. Smith with their orthodontics care. Dr. Smith's whole team is warm and caring as well. We highly recommend them!

Dr. Smith and his team are amazing. I am a 30+ year old male who got Invisalign. The outcome is much better than what I expected. Most importantly, everyone in his office has always been very friendly, provided great customer service, and demonstrated their interest in giving me a perfect smile.
- Alberto
