I'm more familiar with Palmdale then Antelope Valley, but I'm new to CA so I'm still adjusting and getting oriented.
I didn't go to the clinic, I saw Dr. McNulty, he's a neuro with an MS specialty. I believe there are two MS specialist in that facility. When I called to schedule, they could get me in in 2 weeks. I opted to wait and scheduled an appointment a month out. I wasn't in the mood for anymore tests at the time. I was taking a possible-MS break, I guess you could say.
Anyway, they called me 2 days after I scheduled with a cancellation and asked if I could come in the next day. I didn't, but I say all that to say, getting an appointment shouldn't be too difficult or too timely.
