Accredited since 1994



Before The Building Doctor, Esq. LLC. was established, the owner worked as an Elevator Constructor. During this time, he bought his first home and began seeking ways to make an extra income. Gary took on a side job providing maintenance work for a very large real estate company in Lincoln Park. At this time, Gary used his specialties to assist the real estate company with repairs, remodeling, and maintenance work on single-family homes, multi-family unit rental properties, and small commercial businesses. Once he developed a client base, Gary quickly turned his side job into a flourishing full-time business and to this day enjoys the challenge of tackling any job no matter the size along with his crew.



Gary was born and raised in Chicago, where he lived in the Humboldt Park area. He attended Lane Tech High School and the University of Illinois for one year. He volunteered for the Army and was a member of the 101st Airborne Division during the Vietnam Era. After being honorably discharged, he worked various jobs including sales, electrical mechanical draftsman, elevator constructor, and general contractor. In 1976, he started The Building Doctor and began making a long list of satisfied customers. Gary still resides and works in the Chicagoland area and is here with his crew to assist with any home repair, remodeling, and maintenance you may have.
