I had the same issue last year. I called the school and they sent me a list of OD's who are affiliated with the school. The first 3 doctors refused as well, but the 4th one I called was willing to let me come in. I don't remember his name (last name starts with 'I', I think and he was Japanese). He practices in Culver City. A REALLY nice guy, he spent a lot of time with me when he didn't really have to. I sat in the exam room and observed him, he than showed me all the equipment and how to use it, it was really neat. He also had his technicians show me all other machines. Don't remember names now (I did learn them for the interview through), but one was to check the peripheral vision and another lets you see inside of the eye on the computer screen. I had a chance to see a healthy eye picture and several at various stages of glaucoma. Anyway, I had a really good experience. Good luck! 👍
