BOSTON — Energy and Environmental Affairs (EEA) Secretary Rebecca Tepper announced the appointment of John Monaghan as Colonel of the Massachusetts Environmental Police (MEP). 

 

Monaghan succeeds Colonel Christopher Mason, who has served as Interim Colonel since September 2024. 

 

"John Monaghan's extensive experience and leadership are exactly what we need at MEP. His innovative approach to law enforcement and his commitment to environmental protection will be pivotal for the department's success," said Secretary Tepper. "I would also like to extend my heartfelt gratitude to Colonel Chris Mason for his exceptional service during this interim period. His expertise and dedication have ensured a seamless transition." 

 

MEP, an agency within EEA, is dedicated to protecting the environment and natural resources of Massachusetts through rigorous enforcement, comprehensive education, and proactive public outreach.  

 

Monaghan started on July 7.  

 

"I am honored and excited to join an agency filled with dedicated professionals who work tirelessly to protect Massachusetts' natural resources and its people," said Monaghan. "Having come full circle from my studies at Sterling, a Natural Resource Management School, to interning with the U.S. Fish and Wildlife Service and working with the U.S. Forest Service, I look forward to continuing and expanding MEP's remarkable work in safeguarding our environment and promoting public safety." 

 

"It has been an honor to close this chapter just as I began my career – serving in environmental protection," said Mason. "I'm grateful to the administration for their confidence in me and for the opportunity to support the department during this important transitional period. John is the right person for the role, and I'm confident the department will thrive under his leadership."
