Keith Pallesen March 16, 2022

Dr. Sebastian performed Mohs surgery on my husband yesterday. He explained all scenarios and options and answered our questions with a caring and patient manner. He, his assistants, and reception all seemed to communicate well together, and with us which was comforting. They even called today to see how husband was doing and to answer any questions. Would recommend this practice.

Lynne Volante August 18, 2021

On my first visit Dr. Sebastien figured out was going on right away and came up with a treatment plan. I’m very thankful a friend referred me to this office. Great front office staff as well.

Eric Beane July 28, 2021

My first dermatology visit and it exceeded my expectations. Dr Sebastien was very thorough and professional. He and his staff were friendly and welcoming. I can say without reservation that I found my permanent dermatologist.

Patrick Markowitz June 23, 2021

Love this practice! Dr. Sebastien and his team treat you as if you're their only patient. He takes time during your appointment to discuss whatever issues you're having and to talk about possible solutions. Recently did microneedling here and LOVE the results! Samantha's bedside manner and personality makes the whole experience even better. It really makes a difference for scars and overall skin texture. Highly recommend!

Rania Hachwi May 18, 2021

Dr. Sebastien and his staff are very personable and professional.

Catherine Renner April 19, 2021

Dr. Sebastien was so quick and thorough - I felt so taken care of. All of my concerns were addressed and nothing went unnoticed by him. I was worried I was going to be waiting a long time because of the other reviews but the wait was probably 10 min max (I had a 9am appointment).

Meghan Marron April 9, 2021

Dr. Sebastian was careful to check for skin conditions over every area of my body including scalp and feet. He had an associate in the examining room the entire time and answered every question I had. He offered suggestions when I asked about a few areas I’d like to improve. Took his time and was pleasant.

Denise Waters April 7, 2021

Dr. Sebastien takes the time to answer all your questions. He solved my problem and he's incredibly knowledgeable. This office offers a wide variety of services and it's up to date with technology. The entire staff is friendly and made my visit exceptional. I'll be back.

Laura Dunmyer March 31, 2021

Great visit today. Kind and helpful staff and Dr Sebastian took the time to explain things and put Me at ease. Highly recommend!

Roger King March 18, 2021

Been seeing Dr. Sebastien consistently now for at least five years, including the removal of one massive basal cell that was complex to say the least. He does a great job making sure all questions are answered, describing all options to consider, and spending sufficient time with you each visit.

Bob L February 15, 2021

Dr. Sebastien was extremely upbeat, friendly, personable, knowledgeable, and took the time for questions and answers. More than 2 decades of experience and finely honed skill make this the ideal practice.

Architektos UX & DevOps February 3, 2021

Been seeing Dr Sebastian for well over 10 years now. I started seeing him when I noticed a bad looking mole appear. He diagnosed it as melanoma and helped me find a surgeon to remove it. I've been seeing him twice yearly ever since. He's very thorough in his examination and takes the time to answer all my questions. I've moved many times since those early days of seeing him (living in Spotsylvania now), but when you find the best dermatological care, you don't mind driving the extra miles to have a quick check-up.

Steve Newton January 27, 2021

I was fortunate to find Dr. Sebastian 21 years ago for Mohs surgery. Fast forward, a week ago I was sitting in his office for treatment. His expert technique gives you a 99% reassurance that you are cancer free. Dr Sebastian is “famous” for Mohs surgery and is my “one and only” stop as I address cancer and the removal with certainty. He and his team are kind, understanding, while giving comfort each step of the way. Trust his care for your health!! PS I live in Texas and stayed in VA for an extra month to put my health in his expert hands. I move on with certainty to a healthy future.

Brente Hansen January 25, 2021

I highly recommend Dr. Sebastian. He was not only competent, courteous and professional, he listened! Dr. Sebastian asked numerous questions and gave a thorough examination before ever offering his recommendations. Lastly he thoroughly explained what I was experiencing and how his recommendations would mitigate the adverse symptoms I was experiencing.

Craig Woodfolk January 21, 2021

Professional and knowledgeable. Quickly diagnosed issue and very friendly.

Stephen Constantinides January 11, 2021

Dr. Sebastien and his staff removed a Squamous Cell from my forehead and could not have been more informative, thoughtful, thorough and efficient.

Bill Putman December 19, 2020

From treating melanoma and performing required skin cancer checks to approaches to hair loss, Dr. Sebastien and his team are cutting edge. Conditions are explained in terms anyone can understand and treatment options are presented. The team's patience, compassion, and accessibility are boundless.

Jojo Pap November 18, 2020

Dr Sebastian is caring, honest and most importantly a master at determine exactly what you need to look younger. I have been to other doctors for fillers, etc and they just try to sell you and make money. Dr Sebastian is not that way in the least. He is skilled with his tools and you will get great and lasting results like I did

viviane deering November 15, 2020

Dr. Sebastian diagnosed my case in 2 seconds and prescribed the right medication for me. My primary care physician prescribed two rounds of the same antibiotic and my skin didn't clear up. If you have a skin ailment go see Dr. Sebastian. He's a very nice guy and is great!

Peter Radvanyi November 23, 2019

Dr. Sebastien is very professional and well qualified. He is very polite and correctly identified what was needed to address my situation. He is smart and very confident. I highly recommend him for accurate, quick results!

Frank X January 6, 2019

I had been told I needed to have a cancer cell removed, but my dermatologist wasn't in my insurance. I found Dr Sebastian in Arlington & my first consult was timely. He asked about other family cancers & asked if I had an overall body check (I had). He said because I am so pale & family members have had skin cancer, I must be checked yearly . The day of the surgery, they were on time, professional & he entertained me during the procedure. While I waited for results, they fed us pizza! Extra points for thinking about patients waiting sometimes hours & need to be fed). He repeated instructions & warnings. I was impressed with his knowledge.

Diane S.E. November 26, 2017

I have visited Dr. Sebastien twice, once for a routine assessment, and once for a brief office procedure. I have found his office to be completely organized, with an appointment reminder via email. Each visit I have been shown to an exam room within 10 minutes of my appointment. Each visit I have been seen by the Dr. within 10-15 minutes of being in the exam room. I find the Dr. to be completely cordial and engaging, and the time spent with me is entirely appropriate to the appointment - a little talk about sports or the weather, an exam, a handshake, again, completely in line with my expectations for a professional visit. I don't have any hesitation to recommend this Dr. or this office based on my two visits.

Tim Bryan September 12, 2016

I have to respond to the Oscar the Grouch comment. He may not be as warm and fuzzy as some other doctors, but Dr. Sebastien's diagnostic skills and professional reputation are second to none. If you want the absolute best dermatologist in the region, or have any suspicious moles, I highly recommend that you make an appointment with Dr. Sebastien. He is a Mohr's expert and will catch things before they progress. I have been his patient more than 10 years, and trust him very much.

G Obermann March 30, 2016

I was seen right away. Office appearance was very good. Staff was friendly. Dr. Sebastien was very thorough and the exam was very fast. He answered all my questions and provided advice. He seemed very knowledgeable and professional. Overall I was very satisfied.

Great experience!

Karen Gann June 17, 2015

Dr. Sebastien and staff were very accommodating and even though I needed a specific test done, he was able to take care of it on the same day. It was pretty easy getting an appointment within a week or so, as opposed to other Dermatologists I've experienced before.

Sha Islam June 17, 2015

Amazing experience! He is very professional, calming, and did a great job examining me. The staff is also fantastic. I highly recommend this practice. I will be back.

Jenalyn Johnson June 17, 2015

Excellent staff and knowledgeable doctor.

Amanda Hughes June 17, 2015

Quick checkup and good to go. Nice and easy.

Jason G. June 17, 2015

First time ever that I've gone to any physician's office on time, filled out paperwork, had a nice chat with the receptionist, lead into the examining room, met with doctor within five minutes, excellent rapport, no nonsense, listened to our concerns and explained procedures, and left, all within 45 minutes! Highest recommendation and is well deserved.

James Falkner January 29, 2015

Dr. Sebastien is an excellent doctor. I was seeing another dermatologist about a large mole that looked like melanoma but the doctor was not concerned and said we should watch it. I mentioned this to my family doctor and he referred me to Dr. Sebastien. Dr. Sebastien took one look and said that it time to stop waiting to see what it was and have it biopsied. The results came back as melanoma. Since then I have had a number of moles biopsied and removed. After a couple of 6 month checkups that showed me to be clean they transferred to another doctor in the practice. Overall I am very happy. I have read other comments about his practice and I can say that sometime I have had to wait awhile before being seen by the doctor but I find this a normal practice with other doctors that I see.
