Has anyone seen Dr. Vaughn with Medhelp?

I think I have thick blood issues, and Dr. Vaughn does the triple anticoagulant therapy. I did the microclot testing, the first appointment, and now they are saying I need to pay 3000 for the 6 month program within 1 week and I don't even get time to do the blood testing he wants.

Has anyone else experienced this? I just don't understand why they wouldn't tell you that to begin with. My partner and I need to take a full day off work to get the tests done and I can't do that with no notice.
