History






Doorologist provides sales, installation and repair of interior and exterior doors to a wide variety of commercial businesses. We are dedicated to serving clients nationwide through the sales, service and support of our products.


Doorologist was founded in 2005, by John Nelson, more commonly known as the door whisperer. He has passed on his knowledge and that's what makes us such a unique company. Doorologist is designed to provide servicing, maintaining, and installing all types of doors and hardware for commercial buildings and locations. As the company continued to grow, it looked to affiliate with integrators and security companies. We are also certified fire door assembly inspectors which allows us to conduct annual inspections of fire doors.


Eventually, Doorologist expanded from basic door repair to providing and installing security electronic locks, ADA electric operators and specialized hardware.


Today, Doorologist clients include leaders in the hospitality, healthcare, real estate management, retail and corporate sectors.
