As partner of ELA Group, an Engineering and Landscape Architectural firm, Grant W. Hummer, P.E. has been involved in many different types of projects in Warwick Township. As the Township Engineers for over 20 years, Hummer and ELA Group have reviewed and developed plans for many municipal and land development projects in the area. But Hummer, a Lititz resident for over 30 years, does much more than review plans. He is deeply involved in making plans and donating time and energy to projects that make Warwick Township a better place to live.

Over the past 35 years, Hummer has been on many boards and active in many associations including the YMCA, Lititz Community Center, Masonic Lodge 587, Camp Shand, Young Men’s Business League, MS Society and Lititz AMBUCS.

As part of Lititz AMBUCS, a group focused on creating mobility and independence for people with disabilities, Hummer’s most recent focus has been on Harmony Playground, an inclusive playground at Dean Saylor Memorial Park (formerly Linear Park). The playground project was organized by Lititz AMBUCS.

The playground is designed with equipment that is accessible to all children. The first to be installed, a Liberty Swing, is a large swing designed for children with disabilities. In all, there are ten pieces of accessible equipment, including a spring see saw, a glider and safety swings that allow children to swing high without falling.

Hummer and ELA Group employees donated time and services to the project. Landscape Architects at ELA Group drew up the plans for the playground and coordinated the construction with the township. Hummer personally helped with many of the fundraising activities alongside his son, Derek Hummer, who has been active in securing funding for the project.

With his three grandchildren, Hummer has enjoyed the park. Speaking about the park, he says, “It’s a park for everyone, nobody is excluded. All the kids can play together.”  And he smiles. “That’s what it’s all about.”


ELA Group, Inc. employees met for a Sunday walk, all for a good cause.  Leading the group was Grant Hummer, President Emeritus of ELA Group, Inc. and a longtime supporter of the MS Society.

The walk is a major fundraiser for the MS Society nationwide. Participants walk to raise donations. This year the local walk had a 1 mile and a 5k option.

Actively involved in the MS Society for over 25 years, Hummer has been on the local MS Society board and is currently a member of the National MS Society Board.

Hummer and ELA Group also work with the MS Society during the Christmas season. The employees “adopt” a family that the MS Society is working with and donate Christmas gifts, grocery gift cards and other necessities. “We all like to give back, and we make it fun, wrapping the gifts together in the lunchroom,” explains Hummer.


ELA Group, Inc. is pleased to announce that Tyler E. Hill has earned his Professional Engineer License from the Commonwealth of Pennsylvania. Hill is a Project Engineer with the Engineering and Landscape Architectural firm.

Hill joined ELA Group in 2015 after graduating from The Pennsylvania State University in 2013 with a Bachelor of Science degree in Biological Engineering with a Natural Resources Option and minors in Environmental Engineering and Off-Road Equipment Engineering. He is also a 2008 Warwick High School graduate.

Since 1996, ELA Group, Inc. has provided a wide-range of Engineering and Landscape Architecture solutions to both the private and public sectors. In addition to the corporate headquarters in Lititz, PA, they have offices in State College, and Butler, PA.

Through its collaborative project approach, ELA Group combines the design nature of Landscape Architects and the scientific nature of Engineers to yield project solutions that are innovatively conceived, creatively designed, and technically sound.


In furthering ELA Group’s succession plan, during its Annual Board of Directors and Shareholders Meeting, the transition to its new leadership team was completed, when the following Officers were elected: Charles R. Haley, Jr., PE, President and Shawn H. Loose, Treasurer. Cheryl L. Love, RLA, was re-elected to continue in her role as Secretary.

In assuming the role of President, Mr. Haley replaces Grant W. Hummer, PE, who has served as ELA’s President since 1997. Mr. Hummer will continue with the firm, serving as President Emeritus.

As officers of a mid-sized firm, Haley, Hummer, Loose, and Love will also continue to fulfill their roles in the day-to-day operations and management of their respective disciplines: Civil Engineering, Municipal Engineering, Traffic/Transportation Engineering, and Landscape Architecture.

In his twenty years at the helm of ELA, Mr. Hummer steered the firm toward achieving its mission and vision as a multi-disciplined consulting firm. More importantly, Mr. Hummer was and will continue to be the embodiment of the firm‘s culture: upholding high ethical standards; assuring client satisfaction; building trusting, personal relationships with clients; highly-valuing the firm’s employees; and, developing a strong sense of community. In his new role, Mr. Hummer will continue to be actively engaged in community service endeavors.

ELA Group is excited for these leadership changes; they assure continuity in the levels of service and expertise that the wider-community expects of us, while positioning ELA for continued growth.
