Garramone's in Florida, Brownstein is in California (San Francisco I think?). Personally I think Fischer's great for peri but I'm not such a fan of her results for double incision mastectomies, but it's personal preference. Brownstein's probably the best for double incision, but Garramone's also good and one of the cheapest. Those are probably the big three, but you might also consider Christine McGinn in Pennsylvania--it's somewhat close to Michigan, and she is trans herself, although fairly new on the scene. I've heard good things about Perry Johnson in Omaha, Nebraska as well. All of that is for double incision though; if you qualify for peri that's a big difference! Here are the normal costs of each surgeon according to transbucket, but this does not include whether they charge for consultations and/or revisions (I know Garramone doesn't charge for either):
Fischer double incision=normally $6800
Fischer peri=approx. $7400, but varies between $7000 and $8000
Garramone double incision=$5700 always
Brownstein double incision=approx. $7500
McGinn double incision=$6800 (from website)
Johnson double incision=$5350, $6300 (only two results listed on transbucket)
There's also a Dr. William Kuzon in Michigan whom I'm not familiar with who has one result listed on transbucket. No cost was listed and I couldn't find his website, but he might be worth looking into!
Definitely check out transbucket when you get a chance, it has before/after pictures of a lot of surgeons and has been really helpful for me!
