Hi all, Well, you've probably heard a similar story before... I went to Mayo and got a POTS diagnosis and now I'm looking for a doctor in LA for follow-up. I found the two below but haven't tried getting an aptm yet. I can't believe there are only 2 POTS doctors in LA?! It would be really great to find one in the South Bay area (south of Santa Monica, west of Long Beach). There must be 1000 doctors in this area. -Jesse Dr. Frisca L.
