Steven Serrano, CWT, CEO


Steven Serrano is co-founder, owner, and CEO of NYC-CTIS: NYC Cooling Tower Inspections and Services. His philosophy, energy, unparalleled understanding of water systems (domestic water and cooling towers) and compliance have made him a respected leader in the NYC Water Treatment Industry and Compliance Field.
Steven takes a hands-on approach to running the company, and, in fact, still manages several critical projects in NYC every year. 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.”
“I have 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.” 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.
Steven began his career in water treatment in the mid 2000s as a technician for one of the largest NYC water treatment vendors;  he was promoted rapidly through the ranks to foreman and then, shortly thereafter, was trained under the tutelage of the president and other higher executives. He has served in executive level positions ever since with several of NYC’s largest water treatment companies before starting NYC-CTIS.
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 and loving father, a Certified Water Technologist (accredited through the Association of Water Technologies), and a NY/NJ State – Commercial Pesticides Applicator.
