What Our Patients Are Saying About Us

Dr. Armstrong is one of the BEST! We started seeing him and his staff last year due to an emergency call that our actual dentist wouldn’t respond to. Dr. Armstrong took my call even though we were not currently patients of his and he took amazing care of my daughter! We immediately switched to this practice and have been thoroughly happy and impressed ever since. We love the entire staff here!!!

Do you ever go someplace and you are in and out - not quick or rushed - all is taken care of and your experience was great? You also may not even realize it was great, because you kinda hope for it, but in most situations it does not happen. Well, going to Dr. Armstrong is this great experience. Great service and care! Thank you!

I have been a patient of Dr. Armstrong for more than 10 years. The staff has always been very helpful to get me in ASAP when I'm in need of service. I actually enjoy going in to this office. I have found everyone very courteous and friendly. Recently while I was in the office I was able to "stop and appreciate the flowers" while Dr. Armstrong was providing quality service. I really enjoy being able to smile on my way out!

What an amazing office! They make you feel like home from beginning to end! We came in for a chipped tooth and told them we were interested in a cleaning, and to fill a cavity in for my husband as well -and to our surprise they were able to do it all at once! Saved us a trip! Definitely will be coming back for my husband's cleanings and mine.

One of the better dental offices that I have been to. Up-front, friendly staff, and excellent care. The fun part is, any procedure taking more than 30 minutes, you get select a movie and watch while they are doing the work (of course, I never have gotten to watch a whole movie, but it does give you something to do instead of laying there staring off into space).

Like so many, I get highly anxious when it's time to go to the dentist (even for something as simple as a cleaning). Mallory and Dr. Armstrong were wonderful. Mallory was so kind and gentle! They take their time with you and make sure you're comfortable. The care they show makes a huge difference!

Dr. Armstrong and his team are warm-hearted professionals with the high quality service and a state of the art facility. I’ve been a patient of Dr. Mark for more than 25 years and can rely on his experience to take great care of my entire family, from my 82 year old father to my 3-6 year old grandchildren! He’s the best!

Growing up I was always terrified of the dentist, but my experience with them was nothing less than amazing. From the understanding and knowledgeable staff, to the amazing work done, I left with a (much better) smile on my face!

I am beyond grateful to have found Armstrong Dentistry. In the past, I avoided dentists for years at a time due to unfortunate experiences. The Armstrong staff allowed me to relax and receive treatment, confident that I was in the hands of skilled compassionate professionals.
