Last week I had the pleasure of giving a speech on LGBT diversity to Naval Support Activity Philadelphia employees for pride month. Defense Logistics Agency Troop Support employees work on NSA Philadelphia. Thank you to Alex Siemiatkowski, Tiffany Goodwin-Millican and Karen Faber for providing the photos. Also a special thanks to Dori Walsh for inviting me.
