The members at Laura's Playground list one Alabama endocrinologist in their transgender friendly endo list:
Dr. Huey G. McDaniel, MD
1700 Spring Hill Avenue Suite 100
Mobile, AL 36604
(251) 435-1200
Looks like he is still practicing at that address/phone number.
He is also listed in Gender Bender's June 2012 transgender resource guide, and on Facebook by the trans men at Gulf Coast Trans* Responders.
I also found references to two trans-friendly family practice doctors who follow the HBSOC:
Dr Frank Gogan MD
3042 Mcgehee Rd Montgomery AL 36111
(334) 832-1914
Scott R. Weisberg MD
2151 Highland Ave South, Suite 320
Birmingham AL 35205
(205) 877-8677
