Dr. Jordan Hui is the optometrist for the Sam's Club Optical Center. The great news is you do not need a membership to Sam's Club to visit Dr. Hui, just use the entrance to his office on the east side of the building. (You DO need a Sam's Club membership to purchase glasses/contacts from the optical center)
I originally started visiting Dr. Hui because his office was close to where I was living at the time, and even without vision insurance the prices for both the exam and contacts was very reasonable.
Dr. Hui is friendly and informative, he explained my different options for contacts and let me know ways I could save money on them like rebate offers different brands had available. That is why I continue to go to Dr. Hui every year for my eye exam.
