Upcoming Volunteer Service Days

CANCELLED: Monday, 1/21 - Martin Luther King, Jr. Day of Service

Due to the frigid and icy forecast, we are rescheduling our Martin Luther King Jr. Day of Service to Saturday, April 20th.  Read more and register below!

Saturday, 4/20 - Martin Luther King, Jr. Day of Service (Rescheduled)

Saturday, 4/20
9 am – 1 pm
Meet at Thomas Mansion

This event was rescheduled from 1/21/19. Thomas Mansion in Germantown is a historic property built in 1869 by George Clifford Thomas and his wife Caroline Sheetz. The property, which once boasted beautifully landscaped gardens and a green house, needs lots of regular maintenance to keep from becoming overgrown. For each of the last two MLK days, we’ve worked on the mansion grounds by clearing the overgrown invasive plants along the driveway, a project we will continue on this year. We decided to reschedule this date, which is typically our Earth Day Service Day, as this is a perfect pairing to celebrate the legacy of Dr. King, as well as his leadership on environmental justice.

Dr. King once said, “Life’s most persistent and urgent question is: what are you doing for others?” By volunteering at Thomas Mansion, we will be giving back to our park, it’s users, and the plants and animals that rely on it to live.

Recurring Volunteer Service Days


Trail Maintenance 
Thursdays, 9:00 am – 12 pm
Meeting at various locations each week
Thursday mornings are dedicated to much needed trail work! Work will consist of regular trail maintenance projects including repairing drains and grade reversals, repairing stone work, narrowing widened trails, and emergency trail repairs.

Register for future Thursday work days on our events page!


There’s no better way to be friends than to help us in the park with trail maintenance, invasive weed removal, planting, and general clean-ups from 9 a.m. to 1 p.m. Locations vary by week.

“Friends of Friends”

Join Friends of Cresheim Trail to improve the trails in the Cresheim Creek area. These typically fall on the third Saturday of the month. For more information or to volunteer, contact Friends of Cresheim Trail at info@cresheimtrail.org or 215-715-9159.
