Hear what our patients are saying.

  • I had a great experience. I went there for a 2 nd opinion and was surprised at the thoroughness of the tests involved in figuring out my eye issue. The staff was very professional and walked me through each eye examining machine. Every single machine is cleaned before each patient touches it and the office itself appeared spotless. Equally as awesome was my experience with Dr. J Oats. He explained everything in detail and was not rushing to get through my visit. I highly recommend OCLI. Needless to say they have gained another loyal patient and I will refer my friends/family there anytime they need an ophthalmologist.
    F G.

  • Very clean. Taken in within five minutes. Tech was very polite and answered all my questions. Dr. Oats was very polite and explained results of tests.. I will recommend OCLI to everyone I know.
    Margaret M.

  • Friendly competent professional staff. Very short wait before seeing Dr Oats. Communicated clearly.
    Mike I.

  • Everyone was friendly and professional. Dr. Oates had a nice manner and fully answered my questions. One should expect that nut I have had an experience elsewhere, where the doctor was very condescending. This office is run like a well oiled machine, from check in to the visual tests, drops, then exam. I have found a new Doctor for my family.

  • My wife and I recently had a visit with Dr. Oats whom we both thought was excellent and we were pleased with his professionalism and manner. I must state that my wife and I were both amazed at the rudeness shown to us when I called to make a change in our appointment when speaking to a receptionist named Laura. I had to request to be turned over to another worker who was better trained at customer service service. All other staff members were excellent and very polite.
