Jaeyoung Yoon

AMAZING!! From the friendly and informative front desk to the back office caring and compassionate Dr. Graviett and her assistant Courtney..Thank you!!

Dr. Yoon is a cool cat, I had a very good experience. Front office was friendly, the nurse that assisted Dr. Yoon was also great. Would highly recommend.

Pleasant office staff and physicians. My husband had the Mohs surgery done today and they were all so informative and very helpful.

I’ve been impressed with all aspects of my visits. I trust Dr Yoon…extremely important. His office staff are professional, organized, knowledgeable & respectful. I would refer anyone to Dr Yoon for an effective & pleasant experience.

Our experience with Dr Yoon for my husband’s Mohs surgery was superb! The whole staff was professional and very friendly. Procedure was explained well and completed in a timely manner. This will be our go-to place for future dermatological issues & we will definitely recommend to family and friends

Friendly receptionist. Unfortunately they were not on schedule. Wait time became excessive.

2nd time for Mohs surgery. Felt confident in his care. Great doctor AND staff.

Ratings above says it all.

????

Above and beyond would be understating the care, real care, that I received!

Have always been very satisfied with Dr. Yoon's care as well as that of ALL staff

What an amazing Dr., he removed a mole from the corner of my eye, a surgery that no one else would do...quick, easy with no skin loss. He is professional, yet fun...I can't give him a better recommendation.

I had my first visit to Dr. Yoon at the new Wentzville, Mo location. It was the best dermatologist visit I had ever had! The office is beautiful, clean, sanitized and very nice. The staff was top notch. My visit was excellent. A great addition to the surrounding communities.

Dr. Yoon operated on me three times at his previous location. One was Mohs surgery on my ear. the next was removing skin cancer from my forearm. the third was removing cancer from my nose. He did a wonderful job on all three, but especially on my nose. You can hardly tell it was operated on. My wife, a retired nurse, says she will go to him for any dermatological surgery she needs because she was so impressed by the work he did on me. Not only is he a great surgeon but also a great person, very down to earth. Dr. Yoon operated on me three times at his previous location.

Very impressive and cordial. There is no eagerness to leave the patient; he extends an opportunity to discuss concerns and questions. Background is excellent and the fact he did his fellowship at Mayo is extremely comforting. His staff is knowledgeable and supportive. As a patient you are in excellent hands. Very busy office but all is handled very professionally.

I was late due to traffic and they worked me in no problem. He explained everything well.

Dr Yoon is excellent surgeon, my moms surgery results exceeded my expectations.

Absolutely recommend Dr Yoon

Dr. Yoon did mohs surgery on my lower leg and while I had other medical issues going on at the same time, he and his staff were excellent through this whole experience. He even showed up unexpectedly to the hospital to check on me after being informed by his office staff that I was there. Couldn't say enough positive things about this practice.

The office staff was very organized and pleasant from start to finish. The explanation of what was going to happen was thorough

Dr. Yoon and his staff were amazing! I had a great experience. Kept informed thru each step of the process. High recommendations!

MY 3rd Mohs procedure and as always, the staff took good care of me and Dr Yoon acted like he had all the time in the world. He stayed a bit and chatted, even after the procedure was done. The incision is well approximated and no drainage. It looks great. Now, my eye, on the other hand, has many of the colors of the rainbow. They warned me that might happen and it did!

I had a very positive experience with Dr. Yoon and his staff. Very professional, friendly and caring. I would highly recommend.

Had a procedure done by Dr Yoon on Nov 4th. He is very experienced, and communicated everything exactly how it would go and then the follow up . I would recommend him and his staff to everyone I know who would need this done. First class in every way!!!!

Dr. Yoon is a great doctor, and a wonderful carrying person.

Great as usual

Dr Yoon is a wonderful doctor! Highly recommend

Dr. Yoon is a very experianced & professional individual who runs a 1st Class Staff. He is my all time favorate Doctor. May God bless him & his entire Staff.

Excellent Service

Very friendly, informative, and helpful.

Efficiency and skill combine with a friendly atmosphere to put one at ease.

Everyone is always wonderful. So glad I've been with Dr Yoon and his staff to get through this not always pleasant experience.

The doctor did an excellent job of explaining the options to us and easy to understand. He provided alternative treatments that were very favorable for my elderly mother.

Dr Yoon does amazing work. I had my 2nd MOHS procedure with him a couple of weeks ago and the site is healing beautifully on my face! The 1st scar, also on my face, is barely noticeable.

Dr. Yoon is excellent at his profession! He does an awesome job from start to finish even in adverse conditions where the electric went out and the generator never came on! I would totally refer anyone to Dr Yoon! I couldn't say enough about the doctor himself!

Dr. Yoon is the absolute best doctor I have met to date! He is so personable, honest, and caring. I couldn’t have asked for a better experience! I had a MOHS surgery done on my forehead, I was so nervous about it and he made me feel so comfortable. I can not say enough good things about Dr. Yoon and his staff! I will come back here for sure any other time I need this procedure! Thanks again! Dr. Yoon is the absolute best doctor I have met to date! He is so personable, honest, and caring.

Excellent, Awesome, and Great at his Job. I have known Dr Yoon for more than 10 years and still am Happy with results.

I don't usually write reviews but wanted to highly recommend Dr. Yoon. I had my second surgery with Dr. Yoon on March 5th. It's been a little over a week and you can hardly see the incision area. My wound was pretty deep and on my chin. My co-workers and family are so impressed at the site. I definately commend Dr. Yoon on his work.

Dr Yoon seems to be a progressive, highly attentive doctor with a great personality and ability to relate. Going to him was a delightful experience, unlike some others by who I have been attended. I am so glad I found him for my MOHs surgery.

Dr Joon Top notch!

Great doctor very knowledgeable.

What a great experience with a bad situation. All staff were amazing!

Honest, to the point discussions. Reasonable options offered and discussed. Very professional, understanding, very personable.

Dr. Yoon and his staff are wonderful! Could not be happier with my experience.

Dr. Upon Took the time to explain the procedure and alternate choices. Although my procedure was short, it didn’t seem like he was rushing to get to the next patient.

Minimal waiting time before treatment. Staff was professional and caring. Surgery was very quick and painless.

Absolutely the best experience! Everyone in this office went above and beyond our expectations. Perfect results. Love this doctor! If we ever have a need we will only come here. Recommend to all.

I had had four previous attempts to remove a cancerous growth on my thigh and the cancer always came back. Dr. Yoon performed MOHS surgery and the cancer is gone. The incision took 50 stitches to close and now the scar is barely visible. I experienced absolutely zero pain either during or after surgery. Nothing but the highest praise praise for Dr. Yoon and his wonderful support staff. I had had four previous attempts to remove a cancerous growth on my thigh and the cancer always came back.

Dr. Jaeyoung Yoon was absolutely fantastic. He was extremely personable and downright engaging. He put you at ease – explained what he was going to do and entrusted you with knowledge of how he learned to be so skilled at what he did. He certainly made you laugh and was truly caring about any misgivings you may have and how you were feeling. He never once made me feel uncomfortable for asking the questions that were foremost in my mind. Erica, Courtney and Heather were fantastic – they were very professional and helped make the experience as pleasant as it could be. If I ever must undergo Mohs Surgery again I will entrust that job to Dr. Yoon. Thanks again Dr. Yoon, Erica, Courtney and Heather for a great experience. Don’t forget to get a new picture!!! LOL.

Dr. Yoon was very professional, complete, and informative. MOHS procedure was handled quickly. Nursing staff was exceptional. Caring, complete, informative. Virtually no pain, minimal bleeding. Home wound care was made simple and effective. Staff was flexible in scheduling appointments.

Had two MOHS procedures done for two basal cell tumors. First one went very quickly and smoothly. The second one turned out to be a little more tricky but Dr. Yoon and his staff took very good care of me and things went pretty well. Everything has been healing up nicely with minimal scarring. Was pleased with the whole experience. This will be the place I go if there is a next time. Had two MOHS procedures done for two basal cell tumors. First one went very quickly and smoothly.

Dr. Yoon and his team took very good care of me. After the consultation, he made arrangements for me to come in quickly for surgery. I had aggressive squamous cell on my face. By taking care of me so quickly and doing a wonderful job he really put me at ease. Thanks to you and your team.
