Angela received her Master's Degree in Energy and Environmental Policy from the University of Delaware. Working at Harriet Tubman Underground Railroad State Park allowed Ranger Crenshaw to share both her knowledge of the environment and the legacy of Harriet Tubman, a powerful historic figure and a motivating force for women. While at Tubman, Ranger Crenshaw created two Junior Ranger activity books with the goal of connecting younger generations to Ms. Tubman. The award-winning activity book has been completed by over 10,000 guests of all ages. Ranger Crenshaw took great pride in training and guiding the members of her staff, nicknamed Team Tubman, on their journey to becoming effective interpreters of the difficult topic of American Slavery.In 2020, Ranger Crenshaw transferred to Gunpowder Falls State Park to be closer to family and friends. She is looking forward to working with the Gunpowder Crew to make sure the park is clean, safe, operable and user-friendly and working with community organizations to make sure everyone has the opportunity to experience Maryland’s natural places. 


In her free time Angela enjoys cooking, traveling, spending time in nature and learning about history and the environment. She is honored to be a part of the Maryland Rangers Association and looks forward to working together towards a better future for Maryland Rangers and State Parks.

Chris Grieco is the Assistant Park Manager for both Fair Hill NRMA and Bohemia River State Park, and he is honored and humbled to serve as the first civilian Vice President for the Maryland Rangers Association. Ranger Grieco began his MPS career in 2008 as a member of the Maryland Conservation Corps where he completed two years of service on the Tuckahoe State Park crew. During these two years he gained valuable experience and training, developed relationships with current and retired rangers, and decided to pursue a full-time career as a Maryland Park Ranger. 

Ranger Grieco secured his first classified position in 2011 at Rocks and Susquehanna State Park. In 2012 he graduated from Ranger School, taking an oath to preserve, protect, enhance, and restore Maryland's natural, cultural, historical, and recreational resources. After three years, he promoted to Assistant Park Manager at Fair Hill NRMA where he has spent the past 6 and a half years. Ranger Grieco has been a member of the Maryland Rangers Association since 2020, the year civilian staff became eligible to join as active members. 

Ranger Grieco values his role as it affords him the opportunity to be make impactful decisions at his home park while continuing to serve in a field operation's role. Just like most rangers, some of his favorite days at work are the shifts immediately following storm events...which we have experienced in increasing numbers of late. In these days we may see our parks a bit broken and disorganized, our staffs may be stressed out and feeling overworked, but the transformative clean-up effort that ensues demonstrates the strength and resiliency of our agency.

Ranger Grieco enjoys living in Fair Hill - located in Cecil County - with his wife, Brenna, and their son, Walden. The trio frequently hike, run, and recreate on the 80+ miles of trails just out their doorstep, but they do visit many of the State's other parks to catch a glimpse of what fellow rangers are up to.
