Christopher Grieco

Vice President

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.

Holly Bennett


Holly Bennett III is a retired LEO Ranger from the Maryland Park Service.  Ranger Bennett started his career in 1979, after being Honorably Discharged from the Marine Corps, as a Seasonal Ranger in the McKeldin Area of Patapsco Valley State Park. There he worked as a Conservation Aide at the Hilton Maintenance Complex and Hollofield Area for two years before  he was promoted to Park Ranger in 1983. Holly completed his Associates of Arts degree in Parks & Recreation Management from Catonsville Community College in 1981 and his Bachelor of Science in Resource Management from University of Maryland College Park in 1983.  In 1991 Holly was promoted to the Substance Abuse Unit and worked out of Headquarters conducting drug enforcement operations and education programs statewide.  Assignments at Headquarters included Firearms Training, Beach Management, In-service Training and Criminal & Internal Investigations.  He retired in 2007 and was given a contractual position to return to the Park Service in the capacity to conduct Firearms Training for the remaining LEO Rangers and Civilian Wildlife Management Program.  


In 2008 Holly was recruited as a LTC for the Coach Position at Patapsco in the new CJC Program.  He assisted in the program development, training of CJC Crew Chiefs and creating program policies and procedures and has continued to work in the CJC program to this day.  Holly has been an active member and board member of the Maryland Rangers Association since its inception holding positions such as Regional Representative, Secretary and is the current Treasurer.  


Holly feels his greatest accomplishment was his work with the dedicated group of Firearms Instructors who shaped the firearm training programs for the Law Enforcement Rangers of the Park Service. This group worked to standardize the training, maintain the proficiency and skills, and continually update both procedures and equipment ensuring the Maryland LEO Rangers were always trained and equipped to the highest standards.
