Expertise:  I can't think of any questions that I can't answer. However, I've learned over the years that I hardly hold all the answers in the world. So, if questions arise that I can't answer, first I'll check the Net to see if there are any, and then pass it on the questioner, second if I can't find any I'll refer them to someone who can.

Experience in the area
I, myself, am a 51yr old FtM, currently pre-op, who began on my own transgender journey in 2000, so I'm familiar with what brought me to the realization that I was/am transgender and the trials and tribulations that can come along the way

Education/Credentials
I'm pursuing a degree in psychology (A.A. awarded in 2007, now pursuing my BA - 2009, MA and/or PsyD - a year or two later) and my focus will be with the gay/bisexual/lesbian/trans, particularly in the trans, areas.

I've spoken on college campuses on being transgender as well as every quarter during my time at CC I spoke to the Human Sexuality class as well as the Gender and Society class when it was offered.

I was a pentecostal for 25yrs before leaving the church and now follow an eclectic Wiccan path.
