With a BA in Psychology, an MA in Architecture & Urban Planning, and an MBA from Columbia University, she first became a construction lender for a major commercial bank, and then went on to develop and manage commercial properties.

Licensed as a TRC (Transnational Referral Certified), Ellen has consistently been a Top Producer ranking in the Chairman's Club, nationally rated in the top 2%. 
Leonard Zackon, MBA
Leonard brings 30 years of business education and experience to his work as a Realtor. With a BA in Commerce from McGill University and a Masters in Business Administration, Leonard became the VP of a  national company, dealing with employees, buyers and suppliers throughout North America. Honing his marketing and entrepreneurial skills, he formed his own company ultimately employing over 150 people.
Throughout his business career, Leonard has focused on developing professional relationships as the key to his success. Together with Ellen, his wife and business partner, he formed the Summit Realty Team based on the notion that understanding, commitment and integrity must be the foundation of the team.
The Summit Realty Team
Working with buyers and sellers, both locally and internationally, Ellen and Leonard have developed a reputation for their passion and professionalism.
In a field already crowded with numerous brokers and realtors, they have demonstrated their skills and commitment, and have helped numerous clients buy, sell and rent property, whatever market conditions prevail.
The Summit Realty Team chose EWM, a full service broker, because of its reputation in the field and because it matched their approach to the business of real estate brokerage.  Acquired by Warren Buffet’s Berkshire Hathaway in 2003, EWM provides mortgage, insurance and title services, covering all aspects of real estate for its clients. It is the exclusive affiliate of Christie’s Great Estates, Leading Real Estate Companies of the World, and Mayfair of London, thus providing the most widespread coverage of its properties and attracting buyers from all parts of the global marketplace. A leader in the fast developing technology of internet marketing, it was the first, and remains the strongest, player.
