Patient Reviews

“Everyone was cheerful, helpful and informative.”

“This was my first visit and I was very impressed with, not only the reception staff, but the back office nurses, assistants and doctors. Doctor Brown is very easy to talk with and explained all that she found as she did an overall check, as well as ease any concerns I had over some of the places she checked. I will be making Dr. Brown my dermatologist for all future concerns and visits and feel very comfortable in recommending this practice to anyone.” – C.H.


“Thanks to the entire office for taking such great care of my family!!!!”

“My family and I have been patients of Dr. McGuiness for several years now. I have always found this office to be professional and courteous. The treatment and care we have received has been outstanding. I recommend Dr. McGuiness to anyone I know looking for a good dermatologist. The staff is friendly and knowledgeable and the good Dr. always takes time to explain any follow up required in a way that makes you feel at ease. I simply would not go anywhere else.” – T.R.

“Everyone was pleasant & very helpful.  I did not feel rushed & the Dr. was thorough.  Everything was carefully explained.  Great visit!” – B.M.

“Love Dr. Brown, Guy and McGuiness Dermatology.”

You all did a wonderful job on my little “surgery” and make sure I knew what was going on, every step of the way, which calmed my nerves.  Also, Guy was great at going over the instructions for how to care for the stitches and Dr. Brown called me that evening, after office hours, to see how I was doing.  Never been to a doctors office as caring as yall’s.” – B.M.

I credit his meticulous and conservative approach, his medical knowledge, and experience in assuring I have had no additional occurrences since. I appreciate how he explains what he is doing and why, and how he focuses on my answers when he asks questions. I also appreciate his staff, they are friendly and very good at what they do.” – S.W.

“I have been a patient of Dr. Michael McGuiness since 1999.”

“I have been treated for skin cancer since 1973 and Dr. McGuiness is by far the best dermatologist of all the dermatologists in my ongoing treatment. He is the most professional, most knowledgeable, very informative and forthcoming regarding specific treatment issues. And is by far the most excellent doctor in doctor to patient skills. I have had treatment at both the Plano and Prosper clinics and can highly commend Dr. McGuiness’ staffs for their professional and cordial patient service, both medical and administrative. I am very impressed by all who assist Dr McGuiness in his dermatological services and highly recommend Dr. McGuiness and his staff.” – J.R.

I’m grateful to him and his wonderful staff for providing me with excellent health care.” – J.M.

“If you are looking for a knowledgeable, friendly team of medical professionals, this is your place!”

“I have been to McGuiness Dermatology for years and have had been greeted with nothing but kind office employees and professional medical staff. We moved to Flower Mound four years ago, and I was so excited to hear that they were opening an office close to my home. – C.R. 

“The appointment went well.  Dr. Brown explains everything in detail and is thorough in her examinations.  She is one of the best dermatologists I have ever been a patient of!” – R.T.

“I am so pleased with the results!”

“I was referred by a friend…Extremely Recommend! Great doctor! He found a malignant melanoma on me – on a routine visit. It was a spot I would have never known. It didn’t even look like a mole, just a tan spot that blended in with some sun spots on my upper chest/mid clavicle. Melanoma is very aggressive and moves quickly! It was stage 1, but he caught it in time and had not gone to my bloodstream yet. He did not wait around and moved quickly to have it removed. He saved my life!

Office had a more serious atmosphere. Staff was nice. Doctor was very kind, professional, likable and informative. Get yourself checked as soon as possible, you never know! Everyone age 10 and up should go once a year! I had never heard this…Ask for a routine check up or complete body scan. I just took my 16-year old son. Highly recommend Dr. McGuiness.“ – H.S.

“I was very happy with my first visit to your practice and would be happy to refer my friends and family.  Dr. Brown was very thorough and explained thing completely.” – S.Y.

“Michael McGuiness in FM best around!!” 

“Just moved to the area this past year and needed to find a dermatologist for skin screening. Got a Saturday morning appointment, which was just a few days after I called. Was great! Office is beautifully appointed. Was greeted by receptionist as soon as I walked through door. My appointment was with Dr. McGuiness, and he could not have been nicer. He was very thorough in his skin exam and explained every step he was doing and why. His assistant was very good too, though I cannot remember her name. I had to get biopsies on a few areas, but Dr. McGuiness told me exactly what they would biopsy, how they would do it and provided me as much opportunity as I wanted to ask questions and discuss.

I’ve been going to dermatologists for annual check-ups for past 15 years… and was very worried about finding a good doctor here in Texas. Dr. McGuiness put all my worries to rest and delivered a screening that far exceeded my previous dermatologist. He also discussed some preventative measures I could take going forward, which have never been brought to the table by my previous doctor(s). Really impressed and would recommend this Flower Mound office to anyone asking.” – M.R.  

“Plano Dermatology Associates is a very clean, and has a very professional environment. I am not one to enjoy a doctor’s visit, but when I have gone they were able to make me feel very comfortable. The P.A. for Dr. McGuinness is really sweet and very informative. She talks to you and not through you. Like most of my visits to a doctor’s office, they treat you like a number, well, not there. I would recommend anyone with a child or anyone who is skittish about doctor visits to go.

Also, They have a really amazing procedure called CoolSculpting by Zeltiq. It is a procedure that is FDA approved for fat loss where you are able to lose 20-30% of your fat, and it is thousands of dollars less than Lipo. So, my MIL had it done, and she looks better than I do now! HAHA. I am thinking of getting it done before the summer and I will review with the results.  Check it out!!” – M.L. 

“Highly recommend this dermatology practice!”

“Everyone is professional, friendly and extremely knowledgeable. Thank you, Mickie Mayes for the photo facial and for guidance on purchasing the perfect skin care products. Thank you! Thank you!” – S.L.

“I highly recommend Dr. McGuiness!”

“He and his staff are wonderful, caring professionals who truly care about you, as an individual, not as just another patient. I go to both his Plano & Prosper offices, depending on the treatment needed and both offices are great!!” – C.P.

“Dr. McGuiness and staff have been taking care of my dermatology needs for several years. I have always come away with an excellent experience and my visit today was no exception. From the professionalism to the great bed-side manner, my needs are always met. I would recommend Dr. McGuiness and his staff at this location (Plano) to everyone. Those friends of mine who I have recommended to Dr. McGuiness have also experienced the exceptional care I have. If you need a dermatologist, this doctor is your best bet. You will come away with a smile on your face and the knowledge that you received the very best care.” – M.B.

“I was referred to Dr. McGuiness and so thankful!”

“He truly cares about his patients. After my first surgical procedure, he called me that evening to check on me. Since then, I have had to visit the office for more procedures to get my skin issues under control. Each time, Dr. McGuiness presents me with the best bedside manor. I feel confident that my health is in good hands! I also appreciate the friendly staff and the short wait times.” – J.D.

“Dr. McGuiness has been my dermatologist for a number of years now. I have been to numerous dermatologists beginning in high school. Dr. McGuiness has been the most thorough and trustworthy and while I live in Texas, he will be my doctor. My trips to McGuiness Dermatology are not for aesthetic reasons, but Dr. McGuiness and his staff make every effort to provide a comfortable, relaxed, and supportive environment. One last note about my experiences: Dr. McGuiness adheres to the practice of giving patients all applicable information and allow them to make decisions for themselves. His honesty and transparency are appreciated. I would highly recommend Dr. McGuiness and McGuiness Dermatology.” – D.H.

“I was pleased with Dr. Brown’s service.”

“Dr. Brown is outstanding!” – D.M.
