  • I have never had to have any hospital admission except three pregnancies. I get nervous about health but can honestly say this was more than PERFECT. Awesome staff!!! I could not have had better care!

  • I was cared for so tenderly by each and every person I came in contact with! It started with the caring woman in registration, ALL the nurses, anesthesiologists, and lastly, Dr. Preston, he explained everything very well and is a kind and caring doctor! The surgery center is a great place with great people!
