I would recommend this practice go anyone seeking bariatric surgery. Dr. Lopez and the hospital staff at Hospital Guadalajara were great, and my coordinator Sandra was awesome. I felt safe the entire time and the hotel staff at the Marriott provided the best service Ive ever had at a hotel. No regrets here.
