Gait therapists, where are you?

Has anyone else had as much trouble as I am currently having trying to find a physical therapist who is well-versed in helping a PN'er like me, whose chief symptom is poor balance, and who seeks a therapist who is a good gait coach? In the recent past, my PCP has referred me to several different therapists; each has been sincerely interested in helping me with my PN-induced wobbly gait, but none has had experience with the unique stability challenges those of us with PN have. Because I am 80, it's invariably assumed that all of my balance issues are due to old age. I can accept that some of the issues are due to my age, but not all of them. I would love to work with a physical therapist –– or a gait coach –– who have a history of working with PN'ers like us. So far, I've found none. Have any of you on Connect felt similarly frustrated?
