Principals
Jack Rosenblum
Jack Rosenblum was born and raised in Cohoes. He is a graduate of Albany College of Pharmacy and a licensed real estate broker. He has been in the real estate development and management business for over 35 years.
Jack’s first professional career involved building an institutional pharmacy business. His reputation as an excellent provider of services resulted in his quickly expanding this business from one account to over twenty accounts caring for over 2,000 patients in the greater Rochester area. As business grew, he decided to construct his own building, which included rental space for other businesses. Jack personally supervised the construction and quickly rented this space to four international companies, thus beginning his career as a commercial landlord.
When Jack sold his pharmaceutical business in 1977, he soon decided that real estate offered much more exciting opportunities than pharmacy. After moving back to the Albany area in 1979, he embarked on his new career as a full-time real estate developer and founded Rosenblum Development Corporation. He became the first developer to build office space on Washington Avenue Extension. During the 1980’s the company started with one building within our Corporate Plaza location and later built two additional buildings across Washington Avenue Extension.
He supervised the construction of the first four buildings himself, literally learning the business from the “ground up,” including site development, construction, leasing and property management. Because he was involved in every single aspect of the business, he spared no detail his personal attention. His unfailing commitment to service has permeated our corporate culture.
Jack resides in Albany with his wife. He enjoys golf and travel in his free time, but doesn’t plan to quit his day job as our company’s strategic advisor, dealmaker and quality control inspector.
