Prime Timers of Baltimore (PTB) was officially formed on April 1, 1997, spinning off from the joint Baltimore/Washington DC chapter as membership increased in Maryland. PTB is a member chapter of Prime Timers Worldwide.

Prime Timers are mature gay or bisexual men and the men who admire them. Our members come from all walks of like and some are fathers and retirees. We enjoy the opportunities and friendships that develop with other Prime Timers throughout the world.
