Is good for the immune side of things. I give you 100% cool with them for getting the NK and viruses under control. Dr Vera is new so I don't know much about her. But Dr K or Rey are great.
Word of advice, do yourself a poor's man tilt table test and go see an electrophysiologyst if it is positive. To see results you have to treat OI + Immune system and any other issues (sleep, Thyroid, Gut...). So with them you will address any immune deficiency and Viral stuff. You still need to address any specific issues of any other specialty. The sooner the better if you just sit back to adress the others it will take toooo long.
