About Purnell Orthodontics
Dr. Sam Purnell helped a non-patient with an emergency over a holiday weekend, and some patients get braces the same day as their consultation.
Dr. Sam Purnell comes up again and again for personally checking in on patients and answering questions along the way, including handling a holiday-weekend emergency for someone who wasn't a regular patient. Reviews also point to quick turnarounds when something goes wrong, like a same-day repair appointment for a broken retainer, and to a clean, modern office with small touches like beverages. A few reviews mention friction with insurance and billing communication, but the day-to-day experience of care itself is described as attentive and fast-moving, with braces sometimes starting the same day as the initial consultation.

I can honestly say this was one of the best dental experiences I have ever had. From the moment I walked through the door, I was greeted by a warm, friendly, and welcoming staff who made me feel like more than just another patient. The office is exceptionally clean, modern, and comfortable, with thoughtful touches like complimentary cold beverages that make your visit even more enjoyable. A special thank you to Sam Purnell, who went above and beyond throughout my appointment. He was professional, knowledgeable, patient, and took the time to explain every step of the process, which helped put me completely at ease. His calm demeanor and genuine concern for my comfort made what could have been a stressful visit into a very positive experience. Sam is truly a class act and an outstanding representative of the practice. If you're looking for a dental office that combines exceptional customer service, a welcoming atmosphere, and highly skilled professionals who genuinely care about their patients, I highly recommend this practice. They have earned my trust, and I look forward to returning for my future dental care.
