About Tom

Tom Zannelli has earned the designation of Senior Sales Agent at Paragon.

With over twenty years of real estate experience gained in two major U.S housing markets, Tom specializes in listing and selling single family homes, condominiums and multi-unit buildings.


Tom has extensive knowledge of the San Francisco real estate market with its eclectic architectural styles and construction. He is also an excellent contract negotiator, deal facilitator and problem solver.

Though he has a special love for the older Victorian and Edwardian properties that dot the North side of town Tom is also involved in the emerging neighborhoods South of Market Street, home to luxury condominiums and live/work lofts.


People enjoy working with Tom because he loves his work and it shows. It was when Tom accompanied his parents on their home buying tours at the age of eight that he developed a strong interest and passion for architecture that continues today.


Recognized as an expert in South Beach, Tom was one of San Francisco’s first Realtors to focus attention on the South of Market area that includes the enclaves of South Beach, the South Financial District, Rincon Hill and SoMa. His knack for identifying unique and intrinsically valued properties is an asset in helping his clients find just the right home.

As a member of Paragon’s Mentor Team, Tom helps train new agents starting their real estate careers.


Tom provides outstanding client counseling, education and service through the arduous task of buying or selling a home. His attention to detail and the emphasis he places on educating his clients throughout the transaction has earned him high praise from his loyal clients and fellow associates.

A diverse background in the fields of marketing, advertising, television production and human services helped create Tom’s unique style, the hallmark of his successful real estate career.

Meeting and working with Tom made our first experience (buying a home) in the Bay Area an absolute pleasure. We've dealt with many Realtors over the years, and Tom is by far the best...

Tom managed to generate multiple offers for our property, negotiating a sale price well above the asking price. We needed to move quickly... Tom's advice, strategy to market the property, his contacts, personal attention, good judgement and hard work led to a quick sale at a price higher that we had ever dreamed of.
