H2M – Why Work For Us?

2018 marks H2M’s 85th anniversary. We were founded in the midst of the Great Depression by Henry “Gus” Holzmacher, who courageously started a modest civil engineering and land surveying practice out of his Bethpage, Long Island home in 1933. The nascent Grumman Aviation was his primary client. 

Robert “Bob” Holzmacher came to work for his father in 1953, and together they grew the staff to five. By 1955, business was picking up; with a little convincing, Bob’s college classmate, Norman Murrell, joined the firm. A year later, Bob’s former boss at Long Island Water Corp., Samuel McLendon, came on board, bringing along his background in sanitary engineering and water analysis. Within months, Sam set up a modest water analysis laboratory in the kitchen of H2M’s first “formal” office on West Marie Street in Hicksville. Thus H2M’s laboratory division was born. 

In December 1960, H2M celebrated the opening of its first official office building on Route 110 in Melville, just months before Gus’s sudden passing in early 1961. “This was the culmination of a long-time dream for my father. He and my mother were very proud that day,” said Bob. “His great satisfaction, seeing his engineering firm well-established and in a prestigious office building, was short-lived. But the firm continued to prosper through the years. I know that my father, in his wildest dreams, could not ever imagine the firm growing to its present size and importance.” 

H2M grew to the 50-employee level in the 1970s and to the 100-employee level in the 1980s and ‘90s, establishing its architecture group and adding its New Jersey office along the way. In the years to follow, the firm continued to diversify its professional services and market sectors, responding to Long Island’s rapidly-growing communities and related environmental concerns. And it still does today. 

Bob ran H2M until retiring in 1991, along with Senior Vice Presidents Norm Murrell and Sam McLendon. Harold Dombeck then took over the helm as President and CEO. Starting in 1965 as a sanitary engineer, Harold graduated into an executive position, overseeing H2M’s fiscal health and growth. After Harold retired in 1995, the Board of Directors elected John Molloy, who served as H2M’s President and CEO for the next 17 years. 

“I started at H2M in 1974 driving in from Brooklyn and dropping coins into the toll on the Southern State,” said John. “The firm has meant everything to me and my family and is integral to our lives. I have been honored to lead this outstanding organization for the past 17 years” 

In the last few years, H2M has opened additional offices in Albany, New York City, and Westchester, NY, to better service its upstate clients. Today, President and CEO Rich Humann, who joined H2M as a college intern in 1987, is leading the firm towards continued success. 

“I’m very optimistic about our future,” said Rich. “We have an exceptional group of clients and a very experienced and dedicated staff—it’s the perfect blueprint for success for our clients and for H2M.”

H2M designed and coordinated the relocation of its Long Island headquarters, uniting two previously separate office locations in the process. The new space, which spans over 40,000 sq. ft., incorporates an open office concept, enabling improved communication and collaboration among staff and departments. The space also features multiple "buddy areas" for impromptu group discussions and presentations. 

The space was built out entirely from scratch and incorporates a number of sustainable features. In addition to low- and zero-VOC carpeting and finishes, the new office boasts high-efficiency mechanical systems and low-flow plumbing fixtures, and furniture is composed of 84% recycled materials. To save energy, H2M utilized a layout that maximizes natural light to interior spaces as well as high-efficiency lighting fixtures and occupancy sensors.

A firm doesn’t reach its 85th birthday without the contributions of a highly skilled and dedicated staff. 

At H2M, our people are at the heart of everything we do, and we’re always seeking new talent to join our team. Whether you’re a college student or a seasoned professional, we offer career opportunities at every level, in areas ranging from architecture to administration. 

We’re passionate about our work, dedicated to our clients, and committed to our legacy. We emphasize collaboration and community involvement and promote sustainability in our practice, ensuring that the right projects are developed with minimal impact on the environment. Our integrated approach to design incorporates the diverse voices and visions of our staff into every project. Through mentoring, peer reviews, and professional development opportunities, employees at every level are offered the opportunity to share best practices and gain new experiences.

    I have been working at H2M full-time (More than 10 years)


    If you are a committed employee and a good worker, they will be committed to you and help you do what you need to succeed and develop your career path


    Sometimes management is too nice when they should take a harsher stance, but in the least I can say that they have learned from these areas as they have arisen.

    Positive Experience
    Average Interview


    I applied through college or university. The process took 1 day. I interviewed at H2M (Huntington, NY) in November 2016.


    Had both interview with HR rep and head of MEP department. Both created a relaxed environment for talking about resume and experience. Best interview I have had so far and would recommend trying to apply here to anyone.
