A tremendous emphasis is placed on using the latest technology and under Steven's leadership the company has become an industry leader in the NYC Metro area. He says “No one can predict what a NYC official inspector will do or say. But, our on-going conversations with the NYC Department of Heath and Mental Hygiene (DOHMH) provides us with an excellent frame of reference to guide building owners to a safe road; the road to no violations." Steven believes that there are three goals necessary for quality control for domestic water and HVAC water systems: educate the customer to our innovative way of dealing with compliance, communicate clearly and candidly, and respond AS SOON AS POSSIBLE.” Steven is a member of the Queens Chamber of Commerce and Building Owners and Managers Association (BOMA), where he is active in efforts to educate a number of key executives within the NYC Metro Area. He is also an awesome father and a NY/NJ State - Commercial Pesticides Applicator.
