I went to get my skin checked and usually see dr. Green who is great. He was out of town so I saw Dr. Serota. He asked me if I was vaccinated and said getting the “vaccine is more important than checking for skin cancer” without any prior knowledge of my medical history that included blood clots and never asked me if I had Covid before, which I did. After I said I wasn’t vaccinated he lost interest and gave arrogant responses. Stay away from him.

Christine Porter is by far the best dermatologist and really cares for me as her patient. She has helped me transform my skin from bumpy full of acne to smooth, clear and bright skin. I love coming to see her once a month for check ups and she has great energy for someone who works so early in the morning.
The only downfall of peak dermatology is the front desk staff. Every time I come I am waiting an extra 5 minutes to just check in. They can be blatantly rude to patients and always seem confused and unorganized. I came in this morning for my regular 8 am apt and they told me it was at 9 when

I went here for the first time based off reviews for some dry skin issues, let me tell you, First of all, the receptionist was super friendly and courteous and upbeat even at 8:00 am. I got checked in and was called to the back in less than 10 mins and didn’t have to wait long to see my doc. Dr Greene and Christine are both super knowledgeable, down to earth and have amazing bed side manners, they got in took some samples and wasted no time. Gave me a diagnosis and treatment, literally the same day of using the cream my skin cleared up, this is my go to for skin care for now on!

Very much a bother to be seen at this place. I did NOT see Dr. Green so I can not say that everyone is rude. The receptionist we not friendly to me but ever nice to people that have been there before.I happened to get a phone call while in the lobby. I turned my phone off as fast as I could, said sorry to everyone, no big deal!! The receptionist tells me that there is a sign for no cell phones. Ok, my mistake fir having my phone on... but about two minutes later the receptionist was texting on her phone!! The Doctor that I was seen by, kept grooming himself in the mirror while asking me why I have

I felt the client care was very poor here. People were incredibly unfriendly, the doctor didn't want to answer any of my questions, he just kept telling me he would "give me a printout." I think it was Doctor Serota. He spent about 5 minutes with me and it seemed like he could care less. Very unprofessional in my opinion.

Dr. Greene is Great! There are a lot of dermatologists out there who won’t explain things to you. He’s not one of them. He cares about his patients a lot, and it’s very evident in the way he remembers who you are, even if you haven’t seen him in a couple of years. Every time I’ve had a problem, it’s solved within a week of seeing him.

I was scheduled for a first time appointment hours prior due to an opening that came up (otherwise I would have had to wait several weeks). I relayed that I had never been there and would do my best to find the location and parking with the recent heavy snow fall. I had trouble finding both and called the receptionist who didn't provide me with the help I needed as I was still unable to find the location given her (limited) directional assistance. I very quickly received a $50 no-show bill and called to relay that I didn't think it was fitting given the circumstances. I was told the Dr

Had my first appointment with Dr. Greene - I am a fan. He answered questions, was informative and has a very kind demeanor. He is a CO native and a nice person. I would highly recommend him.

Solidly mediocre experience. The office staff were very cold to me and acted like I bothered them trying to schedule an appointment. My allergy was misdiagnosed causing me to avoid the wrong chemicals for 6 months and continue to have severe reactions until I saw a better specialist who did more extensive testing. They were nice enough to give me extra samplers of an expensive ointment to treat my reactions though, so there's that.

Amazing experience with Dr Greene. Went to the clinic yesterday and had a positive feeling right from the beginning. He took his time to explain everything and helped me with my problem I had. Highly recommend Peak dermatology and Dr Greene. Thank you!

Dr Greene is a personable, truthful, well qualified doctor who is thorough, practical and very talented. He has helped me and my family so much in examinations, procedures and product advice, among many other valuable things. He is a straight-shooter who goes out of his way to make sure you are comfortable. He has a superb sense of humor. My family will never visit anyone but Dr Greene. Be advised: call first to see if he is available to see you as he is quite popular. Also, he accepts Medicare.

I submitted a contact form on their website and waited a week to make an appointment but never heard back. I then called and the phone was answered with "Peak Dermatology Can you hold please thank you" all ine one breath and was then immediately placed on hold. I waited a few minutes and then they hung up on me. I am guessing they are understaffed or not in need of new business so I shall try elsewhere.

The most amazing doctor's office I have visited. Dr. Howe is amazing and very understanding how important it is to feel comfortable with your skin. Desiree goes above and beyond to assist Dr. Howe and is there for all of the patients. The front staff is also very accommodating with appointments and questions. Overall great experience, and look forward to my appointments. Would refer them to all my family and friends!

I went to Dr. Howe about 10 months ago looking for a solution to my acne that had caused some scarring on my face. I had tried many different topical and oral treatments to no avail. After talking we decided I would start accutane, which completely cleared my acne. I have been off the drug for about 3 weeks, and everything looks good.

He was very helpful every time I went in and made sure to spend time answering any questions I had, and talking me through the different side-effects I was having. On a couple of occasions he called me outside of appointment time where I talked with him about some

Sorry for the long review, but they are so amazing I had to brag a little.
The receptionist was great! When I called on the phone she got me in right away and repeated the information back to me so I could make sure that I got it all down correctly. She also gave me very accurate directions to the new office (I had not been to the new office). When I arrived for my appointment she was very friendly and before I knew it April called me back to the exam room. April (Dr. Green's assistant) was also very warm and friendly. She listened to all my concerns and addressed issues that I had even forgotten
