Dr. Gara was wonderful, everyone was so nice. From the nurse that took care of me before and after, loved the Anesthesia guy😌. I can’t say it was pleasant to prep, but it was worth it.

Everyone from check in to discharge were absolutely wonderful. Kris the IV Queen held up to her name. The anesthesia they used was delightful. Quick lights out and gentle awakening. No pain after, a bit gassy and bloating as expected. Great experience.
