Michael Clemente, Business Development Consultant

Michael brings over 8 years of diverse sales, operations and leadership experience, having held positions at some of the top finance and real estate firms in New York City.

His experience in both of these industries has allowed him to become well versed in all facets of business operations, budgeting, and forecasting, asset management, marketing, as well as sales and sales management/training. This experience and knowledge allow him to provide the utmost value to his clients.

Michael first began his career at a private financial planning firm, where he provided a broad portfolio of asset accumulation strategies for high net worth individuals and large businesses. He then transitioned into another heavily client-focused role at JP Morgan where he coordinated the end-to-end service offering to alternative investment clients (hedge fund and private equity funds) and their investors. In his current role, he is a licensed real estate salesperson and holds the title of Senior Leasing Representative for one of the largest developers in the country at Related Companies, where he manages, negotiates, and secures numerous residential transactions across several of their most lucrative assets.

Michael’s achievements in sales have led him to be the top producer in his company. Equipped with this sales experience and expertise, Michael has partnered with Sandler Training NYC, where he helps individuals and businesses improve their sales and business development skills.
