STI/STD testing and treatment
contraception (birth control) and emergency contraception
trans gender/gender-variant services
LGBQ services (lesbian, gay, bisexual, queer or questioning)
They do some outreach work, safer sex counseling, needle exchange, Hep A and B vaccinations, and more.
Hassle Free has a women/trans and a men/trans clinic, they have always been pretty amazing but have done a lot in the past few years to make their services even more inclusive.
