The impact you make: As you consider this gift in celebration of our 10th Anniversary, please take a moment to meet Tamsyn Waterhouse. Her story is a perfect example of what TLC is able to accomplish with your help. Tamsyn's dream has always been to fly, but when she applied to have her medical certification renewed she was told she would have to undergo expensive and burdensome psychiatric testing that non-transgender pilots are not subjected to. That's when she called Transgender Law Center's legal helpline, and we sprung into action.
