\nCompany Description

Lonergan’s Charter Service has been a family-owned and operated transportation company since 1959. The company was founded by John J. Lonergan Sr., and in 2005, after decades of dedicated leadership, he retired and passed the torch to his son, Greg Lonergan, who had been with the company since 1996 and now serves as President.

John’s grandson, Mike Lonergan Jr.—Greg’s nephew—joined the company in 2006 and now serves as Vice President. Dee Lawson, our Operations Manager, has been with us since 2009. Crystal Heitzer, our Dispatcher, joined in 2023, and Juli Taylor, our Office and Human Resources Manager, has been part of the team since 2022.

We are also proud to recognize additional members of our leadership and support staff:

Lakesha Matthews, our Shop Administrator, has been an essential part of the company since 2003.
Our experienced Team Leads—Dimitria White, Kim Spriggs, Tammy McDevitt-Warfield, Shermeen Collins, Dina Monsalve, Anne Marie Robinette, and Cherbilia Chapman—bring a wealth of knowledge to the company. They play a vital role in training new drivers, assisting current staff, and supporting management operations.
Skip Humelsine, our Safety Manager, has been with the company since 2011 and is instrumental in ensuring that our safety standards remain exceptional.

Lonergan’s Charter Service proudly employs over 100 team members, including highly trained and dedicated drivers, bus attendants, office staff, and mechanics. Safety has always been our number one priority. We operate trusted, well-maintained equipment, supported by a staff of certified and highly skilled mechanics led by Lead Mechanic Kent Wilson, who has been with us since 2009. Our maintenance team works tirelessly to ensure our vehicles stay safe, reliable, and road-ready for the employees, customers, and students who depend on us every day.

At Lonergan’s Charter Service, we truly are a family. Every employee is part of that family, and when our customers ride with us, they become part of it as well. Whether you are looking to book transportation or are interested in joining our team, we invite you to explore our site and learn more about what makes Lonergan’s a trusted name in transportation.
