I recently had a colonoscopy and endoscopy at GIEA. It was a fantastic experience. I was nervous about the IV being placed and my nurse Trina was able to insert it immediately. In addition, my doctor, Dr. Stephenson, performed my procedures and I did not feel a thing. When I woke up, I did not have any pain and was able to eat a meal afterwards. I highly recommend them to anyone who has to have either of these procedures.

I had a colonoscopy done here 7 years ago and I needed a copy of the report sent to my physician. I called and spoke with Laurie. She took the information and faxed the report immediately. THIS IS WHAT CUSTOMER SERVICE IS ALL ABOUT! I want to give my personal appreciation and thanks to Laurie for a Job Well Done! Please recognize her outstanding performance. She deserves it!
