Special thanks for performing surgery on my face recently . I appreciate all the discipline, experience, and education you have invested over the years in order to become an excellent surgeon. You are really serving the public well and saving lives as you go. Congratulations to you and your fine firm.
Thank you for taking good care of me. Mohs surgery is difficult. You all made it easier.
Doctor Dhir and staff, I appreciated the high level of professional and personal care. Explanation of treatment, pathology, and care was thorough, appropriate, and excellently delivered. Thanks!
We just wanted to say thank you - not only for your professionalism and expert care - but for your compassion. I've never been blessed with a more competent physician and as you know, we've seen our share. There will be a special place in heaven for you but just know for now that there are people that owe your their life - but you already have our hearts! Bless you Doc! We love you!
Just a brief note to express my satisfaction with the outcome of the surgery thus far. I appreciated you taking time out of your busy schedule to answer my questions. Also, I want to compliment your staff because they're so courteous whenever I call and they're so helpful. I recommended you highly to a friend who is now considering surgery on her face. She sees a doctor at UK but I said she should consider using your services. In short, I'm glad I put my face in your hands.
I wanted to say thank you to you & your staff for the successful removal of the BCC from my forehead. The wound healed nicely & is not noticeable. I appreciated how you shared in advance the details on how you perform Mohs surgery. I enjoyed you sharing your interest in sports cars and racing.
Please thank Jackie, Blanca, and Lindsay who were always so helpful and kind to me and my husband. I thank you for being you!
I appreciate your generosity in allowing me to observe you at work. This was very educational, and now I feel I can properly inform patients about the expected experience when undergoing Mohs surgery. It is clear to me what an elegant, accurate, and effective method to excising skin cancers. I am impressed with the way your clinic is run. The nurses and staff are very professional and responsive to the patients which I’m sure they appreciate. I hope to see you in the future!
I thought I recognized Dr. Dhir and it turns out he had done 2 surgeries on me at HealthySkin in 2017. We meet again thankfully. We also appreciated your air filter system and how cool your office is decorated. Very restful colors.
My contact with your office with questions about the procedure was greeted with full explanations and a courteous spirit. Warmth without professionalism leaves one uncertain; professionalism without warmth leaves one uncomfortable. Gladly, you and your staff combined both warmth and professionalism.
