The Smile Agency Orthodontics & Smile Design: Karen Guinn, DDS

I’ve been a patient of Dr. Guinn since I was about 11 years old, all the way through jaw surgery at 18, and I can confidently say there is no orthodontist I would trust more. She is truly exceptional at what she does. From the very beginning, Dr. Guinn listened to me, explained everything clearly, and always made sure I stayed on track throughout my treatment. Orthodontics can be a long and sometimes overwhelming process, but she never made me feel rushed or unheard. Her skill, patience, and attention to detail made all the difference in my results. What really says everything is that this practice has become a family tradition. My mom came to Dr. Guinn for braces, I trusted her through years of treatment and major jaw surgery, and now my daughter is about to start her own orthodontic journey with her. That kind of generational trust doesn’t happen by accident — it’s built on consistency, excellence, and genuine care. Dr. Guinn and her entire staff are warm, supportive, and incredibly professional. Every visit felt welcoming, and it’s clear they truly care about their patients, not just the outcome but the entire experience. When I say she is the best out there, I truly mean it. We love Dr. Guinn and all the staff, and I wouldn’t recommend anyone else.

I had to come back to Dr Guinn's office today for new retainer scanning and I just wanted to write a review of the great work she has done on my teeth. I had my braces over 20 years ago, and her work has kept my teeth straight and my bite flawless since I had them removed. Thank you Dr Guinn!!!

The Smile Agency has been very helpful in providing excellent care for me. Dr. Guinn has been very informative and provides thorough explanation during each appointment. In addition, my teeth appear better do to her course of treatment!

I love Dana , she’s awesome. Amazing customer service ! I highly recommend this orthodontist , best in West Co ⭐️

The front staff and doctors, both are wonderful. They never make me feel rushed and always work with my schedule on appt times.
