First of all welcome to BWOL Nick. (Starspirit35) One of my MT school instructors was a graduate of Boulder College of MT... I loved the Zen Shiatsu intensive in school and think it's an awesome modality!
And I've taken CE from Clint Chandler who I believe worked @ Boulder College of MT for many years.
You have SOME of the same challenges as the rest of the males on the forum. Read thru this section to find out what particular issues our other male forum members face. We have some great guys on the board and I think you will find them ready to share their concerns and victories.
While some clients may be leery of having a massage from a male practitioner, one of the pluses of Zen Shiatsu as I recall, is that the client stays clothed. And I remember my instructor saying that often the face is covered with a cloth when the tsubo points on the face are worked as well.
Because the client stays clothed, this should make many potential clients feel even more at ease with you. A calm and comfortable practitioner will go a long way towards making potential clients feel they're in capable hands.
I look forward to hearing more about your "journey" Nick!
