I’m not really sure I’ve ever seen or heard of a doctor with a waiver… it seems sort of counter to the idea that they know what they are doing and what they are doing is medically safe. I would be surprised, and frankly a little concerned if a medical doctor’s office had a wavier.
Now, a cosmetic surgeon on the other hand… they are VERY likely to have a waiver… so I would sniff around those types of offices. Tell them you’ll do a free legal review of their waiver form 
True, however a basic indemnification and liability waiver will have all the same legal verbiage. For more info about this issue, check this post in this thread; flexNT installation - #2 by amal
