About Us

Prism Health offers a safe, affirming, and non-judgmental space where all members of the lesbian, gay, bisexual, transgender, and queer community can obtain the compassionate and culturally effective health care they need and deserve.

We prioritize inclusivity to ensure that all members of the LGBTQ+ community can access affirming and high quality health care. Patients do not have to be lesbian, gay, bisexual, transgender or queer to receive care, but services will focus on addressing the sensitive issues of sexual minorities and their families and friends.
