Our firm was originally established serving mainly commercial properties in New York City, which is one of the most complex, highly regulated, aggressive markets in the country.  This early experience afforded us the unique opportunity to design innovative environmental protocols that would later become the foundation on which we built our nationwide recognition.  With offices spanning the United States from coast to coast, Hillmann Consulting, LLC is strategically positioned to provide services in any market. Our goal is to provide creative and cost effective solutions for your environmental needs while maintaining our ongoing commitment to safety.  Our portfolio of clientele includes Property Owners, Property Management Firms, Commercial Lenders, Insurance Companies, and Construction Management Firms.

At Hillmann Consulting, LLC, Your Property is Our Priority. When Joe and Chris started this company their commitment to service was clear, and that continued commitment has proven to be one of the major cornerstones of our success.  We build long lasting relationships with our clients, offering them the peace of mind they need when environmental concerns arise or the unthinkable occurs.

Message from the President/CEO

Hillmann Consulting started operations in 1985 serving the New York City development community with environmental services. I had been working as a safety manager for two different firms and decided to strike out on my own in order to provide the service and honesty that I observed was sorely lacking at that time. My brother, Joe, joined me in early 1986 when our business began to take off. We initially purchased our lab equipment, used, from a local scientific supply company and operated out of my apartment in Montclair NJ. Within months we opened our first office, located in Union NJ. As a young 25 year old, I remember meeting property and construction managers in Manhattan and wishing I looked older. Our first big clients were Olympia and York, and Tishman Speyer Properties.

We grew exponentially in those early days, going from $360,000 in revenue to $3.1 million in our first three years. Today we are a firm of 120 professionals with 10 full-service offices across the country and another 20 professional associates in smaller cities realizing $240MM in consulting revenue. In 2001, we purchased a small construction risk management firm and began providing construction loan monitoring services to a number of large and small US banks and developers. That service line is 6 times bigger today than 2001, contributing to $10 billion in completed construction projects and touching over 100MM SF of real estate.

Hillmann has always been a firm that strives to understand our client’s business goals and incorporate those goals into our approach. Our success has been based on seeing the “big picture” for our clients and matching our recommendations to their goals. This means we find the most effective approach, often greatly reducing project costs and project duration. We are proud to say that the vast majority of our early clients are with us today. Our mantra is “Your Property. Our Priority”.

Joe redeemed his ownership in the company in 2007 but still works as an advisor and service provider from his home in New Orleans. I have brought new owners into the firm to strengthen our team and growth over the last five years and we have doubled in size since 2008. Our biggest challenge with growth is to remain a “family oriented” business that offers opportunity and respect for our employees and their families. We also strive to be good members of our local communities through charitable work and giving.
