Gary Sidell

Gary Sidell is the owner and founder of Bell Tower Commercial Real Estate Group. His professional career started in Lawrence in 1993 when he joined his late father’s women’s clothing company, KGR. During that time, he learned not only every aspect of the manufacturing industry, but more importantly what it meant to take care of their people and the community at large. In 2001, after his father and he decided to close the apparel company, they then focused on real estate by repurposing existing buildings formerly used by the apparel company. Since that time, his business has been focused on restoring historic, under-utilized buildings and repositioning them as thriving commercial properties throughout the region, including medical, office and retail uses, with the most enjoyable part being the relationships formed with his clients and tenants. The company manages hundreds of thousands of square feet of space in the Merrimack Valley and is poised to grow extensively in the future.
