  • Testimonials


    I've been battling acne since I was about 9 years old (I'm 27 now). I've been to tons of dermatologists, most of whom could not care less about actually figuring out what's going on with your skin. Dr. Long-Mitchell makes it her mission to figure it out. She is extremely informative, even if you don't have questions. And she manages to do all that while keeping visits extremely quick. I've never had to wait more than 5 minutes for an appointment, and the one time that I did, she apologized profusely for it.

    After much patience and investigation (and actual listening!), my skin is nearly flawless.

    I'm also extremely fair with many, many moles and freckles, so I use her for regular screenings and mole removals in addition to acne treatment. She removed a mole from my face that I've hated for years (and was very nervous about removing, as I've had previous surgeons do awful jobs on moles before) and did a PHENOMENAL JOB. It's as if it was never there.

    This woman has changed my life. I cannot recommend her enough. I even recommend her to people who don't think they need to see a dermatologist; I'm that passionate about her.
    - CG

    I was given Dr. Wendy Long's name for the surgical removal (MOHS procedure) of a basal cell carcinoma. I do not have enough superlatives to describe this dedicated, sympathetic, and highly skilled physician. She put me at great ease and explained in layman's terms the details of the procedure and on the day of the surgery I was treated with the greatest of care. I have since returned for other procedures (more cosmetic in nature) and I have consistently found her to be the same generous, compassionate physician she was at our first meeting (and she has a delightful sense of humor). I would also like to compliment the office staff- they were very helpful both on the phone and in person and I didn't wait longer than 5 minutes the 3 times I've been in to see her.
    - RB

    Dr. Wendy is a rare find in NYC. I have seen at least 6 top NYC dermatologists associated with NYU and Mt. Sinai Hospitals. I feel very fortunate to have found Dr Wendy Long - Mitchell. Not only does she treat you with respect, kindness and professionalism she actually solved my long standing battle with eczema. And unlike the so called other top dermatologists I've seen, Dr. Wendy spends a great deal of time performing my 6 month skin cancer screenings.

    In addition, I love the fact her office is not so called "medi spa". I have been receiving Botox injections from her for 3+ years - I never look frozen and people ask me how can it be that I do not age. No one knows I have Botox thanks to Dr. Wendy.

    Due to too much sun, I recently had a laser procedure - Dr. Wendy used the scion laser to remove uneven skin tone and reduce redness on my chest. Only one week out and my skin is already even and redness is gone.

    As a very critical person take if from me, Dr. Wendy will change your life. I have sent many of my friends and co - workers to Dr. Wendy - all came back to me with glowing reviews.
    - DS

    For years I have struggled with psoriasis and every dermo I saw treated it as a purely cosmetic type of a bother. The last straw was when the topicals this one woman prescribed were making my skin VERY thin, I complained and asked if there was a pill or something internal I can take and she told me there wasn't. Lo and behold, I meet with Dr. Long-Mitchell and she was able to put me on an oral medication that has been working SO well for me!

    Her office staff is great at scheduling appts and getting your lab results and prescriptions out to you/your pharmacy. I also have never waited to see her - they're very timely.

    She takes notes with her laptop which updates your chart so precisely when she sees you... it's really refreshing to have such a tech savvy Doctor who doesn't just handwrite everything out (more room for mistakes).

    She's also very pro-active and involved in your treatments... overall it is a GREAT practice... best dermo practice I've ever been to.
    - RR

    As a patient of Dr. Wendy Long Mitchell since 2008, I have consistently received outstanding medical and dermatological care. Although I rarely write reviews, this proven and sustained professional excellence has compelled me to share my feedback.

    With a background in the sciences and law, and being raised in a family of physicians, I have always been very particular and conscientious about the selection and retention of my medical and health care providers. I received extremely reliable personal and professional referrals to Dr. Long Mitchell, including from my internist-cardiologist who stated that she "is a superstar" (and he does not give praise lightly); further research illustrated her extensive and impressive education, training, and certifications.

    Dr. Long Mitchell has attended to my dermatological issues ranging from advising on skin protection during travel and general daily skin care to milia removal and cyst surgery. She is a responsive, caring medical professional who provides thoughtful, comprehensive and expert medical treatment. She is an excellent communicator - fully explaining the issues, options and procedures with patience and understanding. She has a phenomenal "bedside manner" - providing comfort, ease and confidence during check-ups and procedures. She has amazing surgical prowess - providing positive results. (The suture site of my cyst removal surgery near my eye is not even visible.)

    As to her office, Manhattan Dermatology, my appointments have been scheduled in a timely fashion and have started on or very near the scheduled times. Helpful reminder calls are made prior to appointments, and check-in and check-out are quick and easy. The staff has been pleasant and helpful.

    With utmost confidence and without reservation, I highly recommend Dr. Wendy Long Mitchell.
    - MM

    Dr. Wendy Long is great! Always friendly and on time - I recommend her to all of my friends.
    - AK

    Dr. Wendy is the absolute top of the line dermatologist specializing is cutting edge surgical procedures. She is also kind, open-minded, and helpful. She has evaluated me, and treated me, as a whole person, not just the sum of my complaints. She also has a delicate and sure hand with elective procedures. I highly recommend her.
    - LLC

    Wendy is fantastic - as is the rest of their office. The office staff and other doctors are prompt and thorough. Wendy is quite personable as well as knowledgeable. They can send prescriptions out electronically as well, which is pretty awesome. I only have great things to say about this dermo practice and have referred many people there.
    - JA

    Dr. Wendy Long-Mitchell is the best dermatologist that I have ever seen, and I saw two in Manhattan before coming to her. I love the fact that she listens to me. I realize that is what most doctors should do, but honestly, most don't. She is kind and understanding and one of those people who just seems to be in a good mood all of the time.

    Also, every now and again I'll get one of those "OMG!" pimples, and she told me that when that happens I can just come there in the morning and tells the folks at the front that it is an emergency, and she'll zap me with a shot of whatever that stuff is that makes it go away. How cool is that? So yeah, you may have to wait because others will have an appointment, but that is very cool of her.
    - SH

    Wendy is a wonderful doctor who really knows how to make the patient feel at ease while taking care of them. I would recommend her to anyone of my friends or family.
    - RB

    I started seeing Wendy in March 2007 after an auto accident. She was tremendously helpful with treatment on minimizing my facial scars. She's as professional and personable as they come.
    - YH

    Wendy is my go-to dermatologist to this day even though I've moved 1500 miles away. I trust her 150% with the my well-being and the care of my skin. She has treated potential cancer spots, taught me what to look for and always been someone I can trust in regards to my skin. I'd recommend her any day and follow her tips and affiliates here in Texas (until I can afford a teleporting machine;)). I've never met a derm like her...she is one of a kind!
    - JG

    Dr Long is my dermatologist and has provided superlative consult and treatment for me. She is at the height of her profession in both knowledge and skill. I enthusiastically recommend Dr. Wendy Long Mitchell.
    - KK

    Dr. Wendy is the type of the physician you'd like to see when it comes to your skin. Always on time, detail oriented physician who really knows her job. For Dr Wendy "there is no stupid question".
    - SS

    Wendy Long Mitchell is one of the finest doctors out there. She is incredibly smart, on top of it, and precise. I highly recommend her as a dermatologist.

  • Testimonials

    I found Dr. Kihiczak to be very professional and efficient. He took his time with me and answered all my questions. He had great bedside manner and even gave me some free samples! I didn't have to wait at all and he stuck to the appointment time which was appreciated. I would highly recommend him and I will definitely be back.
    - A.K.

    Dr. Kihiczak is a very pleasant communicator and is an excellent listener. Often a doctor will listen to the first problem but he listened to things I remembered to say late into the visit. I can think of nothing to fault my visit. Truly a caring and professional person.
    - J.W.

    Saw Dr. Kihiczak today about a bit of an awkward issue, and he handled it in the most friendly and professional manner possible. Seems like a super nice guy, as well as very knowledgable, which is the best combination one can ask for in a doctor. Highly recommended!!!
    - D.B.

    Dr. Kihiczak has been a tremendous presence in my life. He modified my old medication and within a few visits, we found the best solution to treat my acne. My face is finally on the right track. Also, it's very easy to schedule with the front office. Would recommend Dr. K and the practice to anyone.
    - M.S.

    Just a great knowledgeable doc who understands his craft and knows how to talk to and deal with people.. explains what needs to be done in language that is clear and understandable and answers all questions with skill and ease. makes you very comfortable. been back many times and continue to be impressed!
    - J.S.

    I have been seeing Dr. Kihiczak for four years now and have recommended him to family and friends time and time again. He is always on time and really takes the time to listen to me and is open to trying different medications. I am very happy with Dr. Kihiczak and will continue to recommend to others.
    - Patient

    Dr. Kihiczak is a very fine dermatologist. I have a boatload of risk factors for skin cancer, and he pays close attention to every blip on my skin. I've had three or four precancerous lesions removed, and I appreciate the ease of getting an appointment, his pleasant "bedside" manner, and the fast followup on biopsies.
    - M.O.

    Dr. Kihiczak may have saved my life. He correctly identified an obscure rash on my hand and did a biopsy. The results were an indicator of a more serious health issue. He called me to advise I seek immediate medical treatment which I did. So a very big "THANK YOU" to Dr. Kihiczak for your time, expertise and follow through.
    - Patient

    Before seeing Dr. Kihiczak I went to another dermatologist who made me wait 4 hours just to tell me that I would need an mri before he could do the procedure. I know for a fact that an mri was unnecessary so I went to see Dr. Kihiczak.

    Dr. Kihiczak was quick to access the procedure and took care of me on the spot. His confidence put me at ease and I knew that I had found the right doctor.

    The wound healed nicely with minimal scarring. Dr. Kihiczak took the time to explain the procedure and told me it would take a year to see the final results, but it healed in less time.

    I will definitely be going back.
    - B.T.

    Love Dr. Kihiczak.
    Scheduling was easy (they're on ZocDocs), followup scheduling was easy (did it with the doctor who was carrying an iPad).

    Doctor was no-nonsense, down-to-earth, easy to talk to. Straightforward while taking the time to answer my questions in a clear manner.

    Finally, I had surgery with him to remove a cyst. Another dermatologist had botched it --however Kihiczak performed the surgery easily, with excellent results and a smaller scar than the dermatologist I used to go to.
    Definitely recommend.

  • Testimonials

    Dr. Taylor Defelice is the best dermatologist I have ever been privileged to meet. She quickly and accurately diagnosed the cause of my facial acne. Though I did not mention my body acne, she asked to see my upper back and chest, areas that do indeed break out occasionally. In asking about other problem areas, Dr. DeFelice demonstrated her thoroughness and her desire to completely understand the extent of my acne. Her effort is unparalleled.

    Best of all, Dr. DeFelice patiently listened to all of my concerns during my visit. (I cannot tell you how many dermatologists have rushed me in and out of their offices in mere minutes.) For the first time, I felt that a dermatologist was truly invested in improving my skin. The difference between my experience with Taylor and my experience with other dermatologists was significant and noticeable. With Dr. DeFelice, I am extremely confident that my skin is in good hands. By following her advice, my skin has seen dramatic improvement. I am truly delighted to have met this extraordinary dermatologist.
    - Maria D.

    Dr. Defelice is a most competent, thoughtful and kind person. She diagnosed my problem and was most helpful and reassuring. She really listened and responded to my concerns. I highly recommend Dr. Defelice and her office was pleasant and efficient as well.
    - KM

    Dr. DeFelice is the BEST doctor. She found my melanoma, probably saving my life, and since then she's been wonderfully supportive and helpful. Great bedside manner, super kind, incredibly competent. She's the best.
    - EC

    Dr. DeFelice had great bedside manner, asked the right questions, and was really calm and thoughtful about her recommendation. Her nurse was amazing - I had to have blood drawn and as someone who is terrified of needles, I barely felt it.
    - AN

    Dr DeFelice was very nice and very informative. She sat down with me before my skin scan and went over and concerns I may have, I didn't feel rushed or silly asking any questions. She addressed everything I asked with complete answers and some follow up suggestions. I am really glad I found her!
    - AA

    A colleague of mine recommended Dr. DeFelice for dermatology. It has been a struggle to be comfortable with a dermatologist in the past especially in the city. Dr. DeFelice walked me through a timeline of what to expect over the next few months for treatment of my acne. She sincerely listened to the previous treatments I have received and wanted to make sure I reached my goal of laser skin resurfacing after the acne was under control. I highly recommend Dr. DeFelice!
    - BS

    My dad spent three years trying to figure out why he was getting a rash/boils on his head... doctor after doctor couldn't help him. Dr. DeFelice took care of my dad like he was her own dad... and my dad never had the problem again. Love her, really.
    - AF

    Absolutely the best dermatologist I have been to in NYC. She is very knowledgable and the treatment she provides works. I came to her 5 months ago with severe cystic acne and it is now gone. She prescribed the right medication for me and a regimen that I follow religiously. My visit today was about treating other areas of concern on my face, and she spent time going through all of my options. A great friend recommended me to this dermatologist and I would recommend her to anyone else.
    - Patient

    I really enjoyed my visit because Dr. Felice took time to learn my history, answer my questions and give me real one on one time. Acne is something dermatologists see all day so to have her give me the time and individualize her prognosis and steps to remedy makes a big difference to someone that struggles with acne.
    - Patient

    Dr. DeFelice was awesome. She was thorough, helpful, and a good listener. My experience in her office was perhaps the smoothest I've had in NYC. Prefilling the forms on ZocDoc got me into the exam room fast, and the office called in my prescriptions before I even left the building. Extremely positive experience!
    - Patient

    Dr DeFelice is amazing. Very thorough and explained everything she was doing; provided me lots of info and options; all while being funny, attentive and reassuring throughout my visit. So impressed, would highly recommend.
    - PR

    Dr. DeFelice is wonderful! Thorough yet quick and made me feel completely comfortable during my annual skin scan. The front desk and medical assistant team is also very friendly and quick to help answer questions or get the answer if they don't already know. I highly recommend Dr. DeFelice and her staff for anyone looking for a dermatologist in the NYC area.
