Dr. Dhir and staff were great. We appreciate everyone for their help and kindness we were shown.
You are all so kind & caring! Thank you, Thank you!
Thank you for making my unpleasant situation less stressful and not so unpleasant. God Bless You!
Thank you so much for the wonderful care you and your staff gave me. The removal of my skin cancer was a breeze. I appreciated the straightforward information and genuine care. I hope dealing with my insurance is not too big of a headache for your staff. I am thankful they were willing to go an extra mile to get my visits approved. If I am lucky, my employer will realize you are the best choice for their dermatology services. That way, I can continue to have the excellent care you give.
I've been searching for the right situation to use this thank you card for a long time. Can't think of a more appropriate time than now to express my sincere gratitude for your willingness to help me achieve admired post surgical appearance results.
Thank you so much for sharing your talents with me the last couple of years. You have been so kind and you can't imagine what a difference you have made in my life. You are a wonderful doctor!
Just wanted to send you a little note of thanks for being so kind and thoughtful when I had my minor surgery on Friday. It was so nice of you to call me after the surgery to see how I was feeling. I don't think I have ever had a doctor do that and it made me feel good. Thanks again.
Thank you for the Dermabrasion. My nose looks 100% better. You are the BEST doctor I know, and Theresa you are by far the best nurse I ever seen. Thank you for being so thoughtful and making me feel special. I just can't say enough about you two. Thank you.
Dr. Dhir, Erika, & Lindsay, The surgery site on my forehead healed quickly, with no aches, pain, or scarring. You did great. :-) Your "fun" attitude makes my visits a breeze. Thanks Much!!
