Dr Armstrong was pleasant, my objection is that had 3 appointments and never received a diagnosis. I felt I had wasted my money and did not return. The nurse practitioner was rude and I refused to see her again. Dr Armstong took a biopsy and told me what I didn't have but offered no explanation for what was causing my problem.

Dr. Frank T. Armstrong is the best. I have been a patient of his for several years. With both minor and major surgery he always calls to follow up and see if all is well and if I had any questions. Alicia & Andrea are great support and very knowledgeable. Together they are an unbeatable team.

If you are looking for a dermatologist, keep looking. The office staff are particularly unprofessional.

I went to see Dr. Armstrong for my husbands dr appointment in Clearwater. The location was clean and had nice equipment. Staff was very friendly. We love Dr. Armstrong. He was very nice, had great manners and a great sense of humor. He is at a couple locations and was the easiest to get in with. We highly recommend him.

I highly recommend Dr. Armstrong. No question is too silly and he takes the time to insure your understanding of the procedure. He performed Mohs surgery and you would have to look closely to even see the incision. I am new to Florida from the northeast and am very pleased I found such a competent doctor.

I had been to three different dermatologist for my for the terrible itching and cracks on both of my hands. None of them helped me at all and then I was fortunate to go to Dr. Armstrong. He gave me my life back. He helped me immediately, listened to me, explained things to me , put me on the right medication and treated me with great respect and caring. My insurance does not include him on my policy, but there is no way I will see any other dermatologist so I self pay to get his expertise.

Dr. Armstrong is one of the most knowledgeable, kind physicians I have ever run across in my 74 years. He took great care in my treatment, but did, something that put him over the top. He, himself, called me after the procedure to find out how things were going & if there was anything more he could do. I wasn't feeling my best, but his call helped me feel better.

I had been to 2 different dermatologist for my severe eczema problems, and neither one was able to relieve my symptoms. I decided to try one more doctor, and thank goodness I did! Dr. Armstrong was amazing. I found him to be very caring and really listened to what I was saying. After only 3 days of my new medication, my symptoms and severe itching are almost gone! Great doctor and an amazing staff. Thank you Armstrong Dermatology!

We met Dr. Armstrong in 2015, when our son was diagnosed with Hidradenitis Supportiva, a fairly debilitating auto-immune disease that affects the glands and skin. The picture was quite bleak for our son. Dr. A immediately gave specialized attention to our son, and our family, offering not only medical treatment, but emotional support as well. Many times Dr. A has communicated with us, off hours, via his personal phone. Once from Germany while on vacation! His skill and caring are unparalleled.

I met Dr. Armstrong over ten years ago when he was with a large practice. When he left I stayed there for one visit which was terrible and them found Dr. Armstorng as soon as he opened his own practice. I trust him implicitly and have yet to be steered wrong. I have been to both offices and found the staff at each very pleasant. They have also seen my kids and that was a good experience for all.
