Since 1978, Jay Soneff has been serving Denver and surrounding areas with his expertise in commercial real estate brokerage. As the founder, Jay's goal is to help you generate the maximum possible income for your enterprise.
Jay was born and raised in Denver, Colorado, and attended John F. Kennedy High School before earning a Division 1 baseball scholarship to The University of Colorado. In four years, he graduated with a Business Degree in Finance and Real Estate and a minor in Economics. At age 22, Jay became the youngest broker in the state by taking advantage of the new real estate commission that allowed a real estate degree to replace the two years of Salesman status requirement for broker licensing.
In 1995, Jay went back to school and earned his Master's degree in Construction Finance and Management from the University of Denver. With his extensive experience as a developer, agent, and investor in multiple real estate platforms, Jay has dealt with a variety of commercial development, investment, leasing, and management situations.
Jay's experience in sales and acquisitions, land development, construction, construction management, and complex joint venture agreements have given him a well-rounded perspective in all aspects of the real estate business. He has survived several market swings from the late 70's boom to the late 80's crash, and he knows that the market will ultimately separate conservative and stable projects from speculative and over-leveraged properties. This experience has helped him serve all his clients by protecting and maintaining their properties for long-term success.
Jay is married to his elementary school sweetheart, Jan, and they have two children, Jay Jr. and Jaclyn. In his free time, Jay enjoys his hobby as an avid vintage car enthusiast.
