I am a retired RN of the large hospital System in Houston and has managed the Pre-op,PACU and the Endoscopy Dept of the Oupatient Surgery. Customer satisfaction is very important to us. I moved here in Plano after my House was damaged by the flood during Harvey I needed cataract surgery before my transfer and was challenged to find a new MD.I was looking for one closer to where I live and was fortunate enough to have chosen Dr. Ngo . She met all my expectations. Pre and post surgery. Great staff.
