Thomas Castillenti, DO's Resources


"Very nice"

Dr. Castillenti and nurse were very nice.


My first visit was excellent. I loved that everyone was smiling, which is a first good impression to me. Also very helpful at the Information Center. I would recommend this facility to my family and friends. Thank you!

"As a mother, teacher and runner, I am thankful to your staff."

Dr. Castillenti is a hero! I am a single mom and a teacher who really needed a painful cyst removed before school started so I could have time to recover. I had my appointment scheduled to accomplish this. I got care for my daughters and established a ride from one of my friends for my surgery date.. I was informed that my surgeon would not be coming in and I could not get the procedure!!Per my request someone had called to see if any other surgeon could perform my procedure. Initially it was a no.. but then I was told Dr. Castillenti was going to come talk to me. He appeared (in my mind he might have been riding on a white horse, ha ha) and after speaking with me, he agreed to do my surgery! Again, I cried this time overcome with gratitude for him and for the staff who then had to change all of my paperwork to reflect that Dr. Castillenti would be performing the procedure (and they even called to confirm with my insurance that it would be the same cost to me!). No one complained even though I am guessing they had to work hard and late; instead they were all so kind (Sandra, the anesthesiologist, Tammy etc etc). They were all just happy, as I was, that I was getting it done as planned... Dr. Castillenti stitched and glued it and I was pleasantly surprised that it didn't feel worse when it was over.  I can't imagine anyone ever being happy to have a cyst removed from their tailbone, but after the scare that it wouldn't happen after all the help I needed to enlist.. I was so happy I can't put it well enough in words. I am such a fan of Dr. Castillenti and the staff at the surgery center in Zephyrhills!! Thank you all!!P.s. As I came out of anesthesia I allegedly kept asking when I could run again since I have a marathon in November -- luckily since the doctor and staff helped me that day and are fitting me in for my follow up this week, I should be able to train soon for the 26.2 miles. As a mother, teacher and runner, I am thankful to your staff.... Read More +
