What our patients say about us


Dr. Cohen is 'a derm's derm' -- his published research and opinions are sought after by other dermatologists obsessed with the latest innovations in cosmetic dermatology, including lasers, neuromodulators, and fillers. He's also trained many of these derms. Dr. Cohen is arguably one of the best in the U.S., though he's not flashy or self promoting --just intensely focused on achieving elegant, successful results. I stumbled into his practice quite by accident, and could not be happier. His PA Christina is also phenomenal.


I am so pleased with the high level of expertise and care I have received from Dr. Cohen, Dr. Ho and his medical assistants Cristina and Emily. From the Mohs surgery, to a multitude of lasers, to skin checks; the doctors  have been extremely conscientious and strive to have a relationship with their patients.  I am thrilled with the results of my cosmetic procedures and surgery.  In addition, They are kind and very humble providers. It truly is an honor to be a patient of Dr. Cohen and to be a valued patient of his medical practice. Truly the best in the country.. and The World. Thank you Dr. Cohen and Dr. Ho and staff!

Have been a patient of Dr. Stoler for a long time. She knows me well and takes excellent care of my skin. Also gives good and appropriate advice!

Judy Saul

Dr. Joel Cohen was highly recommended to me by several other dermatologists for his expertise in laser technology. I was not only impressed with the treatment I received from Dr. Cohen, but also his wonderful, highly skilled staff. The entire experience was top notch!

Linda Aibel

This is the BEST dermatology and cosmetic location you will ever find! Truthfully they give all the attention and care anyone could ask for. I’m always blown away at their kindness and their service. Doctor Jade Fettig always takes her time to talk to me, answer any questions and recommend the best treatment. Highly highly recommend AboutSkinDermatology. You will love it there too guaranteed! =)

Roberta Rachkovsky

Dr. Stoler is the best!

Karen Maxwell

I have been a patient of About Skin Dermatology for over 12 years. Everyone that I have ever encountered at this practice has been knowledgeable and very kind. I see both Dr. Ho and Dr. Cohen. My skin has not looked this good in years. My whole family goes to this practice. I would highly recommend About Skin Dermatology.


Dr Fettig was great- took her time with me and answered my questions. She has a nice bedside manner and good sense of humor.

Cindy Wells

I used Dr. Cohen for a Mohs procedure. He is fellowship trained and extremely competent. Dr. Cohen remained involved in my follow up care with a plastic surgeon and was always readily accessible and available to address my concerns. Both he and the office staff are caring and committed to providing the highest level of professional service. I highly recommend Dr. Cohen. I think it’s very nice.

Richard Z

I have been impressed with my Botox treatment from Dr Cohen at AboutSkin Dermatology. He and his staff are incredibly professional and pleasant. Maddie is always flexible and accommodating with my hectic schedule. Dr. Cohen takes time and a genuine interest in his patients. I highly recommend him for any cosmetic procedures.
