Great doctor! I couldn’t be happier with the outcome.

I am about 6 weeks post-op from a breast augmentation and a tummy tuck done by Dr. Callahan, and I couldn’t be happier with the outcome. Dr. Callahan is attentive and has great side bedside manners. He answered all my questions and even encouraged me to ask him whatever I thought necessary. He listened to my requests and provided me with realistic information about my outcome. My healing process has been outstanding, and the outcome has been amazing. I wish I had done these procedures sooner. I’m very pleased and would highly recommend him.

Dr. Troy is the man!!!!

I want to share my journey with anyone who is hesitant about coming to the flat side. I had my procedure done with Dr. Troy last week. He was so good to me before and after surgery. I am sitting here 4 days post op I am still in disbelief, I finally did it. I’ve been researching tummy tucks for the past two years. I was referred to Dr. Troy by a friend of mine. I had my consultation with him on 12/1/13, and I knew right away that he was the one for me. I had a consult with a different doctor, but the connection wasn’t there. Dr. Troy is the man!!!!!

I recommend him highly.

Love Love Love Dr. Callahan. He is definitely a perfectionist. He is warm and caring and spends plenty of time answering any question you may have. He did my breast reduction in 2017, and I couldn’t be happier with the outcome. There was an extenuating circumstance after the surgery with my pathology and he had all the information I needed to deal with at my follow-up visit. He was truly concerned and made sure that I was ok before leaving his office. He checks on me to be sure that things are good. I would recommend him highly.

I cannot speak enough on his gifted hands.

Dr. Callahan is the most amazing surgeon I could have asked for. Five years ago, he gave me the most beautiful set of boobs a girl could ask for. Having lost a lot of weight, my breasts began to sag and one was lower than the other; Dr. Callahan evened them out and gave me the perfect-size implants. He spent hours measuring my torso to see the distance between my belly button and nipples, etc. and Took two sizes of implants to the operating room. When I woke up, he was by my side, and I asked him which implants he used. He said he went for the smaller ones because the bigger ones were going to look too vulgar. He is a conservative doctor; if you want a natural-looking job, go to him! A lot of people cannot tell I have implants, they have fallen so nicely. I cannot speak enough on his gifted hands.

A wonderful surgeon.

Dr. Callahan is the most down-to-earth doctor I have ever had and he spends true quality time with his patients both in the office and the hospital. He returns phone calls promptly and is a wonderful surgeon.
