I began my Real Estate career in San Francisco in 1973 selling investment properties. 

In 1975 I opened, along with a partner, San Francisco Land Co., a successful Real Estate Brokerage firm.

In 1980 I  left the San Francisco market and began a new company which specialized in the formation of investment groups which bought and sold Real Estate investment properties such as shopping centers, medical buildings, and apartment buildings in Arizona, Texas, and California.

In 1990 I made a decision to change the focus of my Real Estate business to residential property,(although I have continued to handle commercial  transactions as well).  I began my own company called “Bill Stewart Realtor”, which operated independently and successfully until January 1997. At that time my wife, Nancy, retired from a 25 year nursing career to join me as a partner and together we chose to join Frank Howard Allen Realtors. We selected the Novato office as a base because of the proximity to our home in Indian Valley.

In 2000, we opened Provident Real Estate to continue to grow in excellence and serve our clients at a higher level.  We continued to operate successfully for 10 years.  As the market contracted, with the growing pressures of ownership and management of the current economy, we decided to merge with Alain Pinel Realtors as of January 1, 2011.  In November 2016 our team received an offer to align with Coldwell Banker Residential Brokerage. After carefully considering the company’s “international reach” and other numerous service benefits made to our clients, we agreed to accept the offer.

In 1997 I joined my husband Bill in the Real Estate business, after a 25 year career as a nurse.  I had worked as a discharge planner and care manager for the elderly at Kaiser in San Rafael. Like most married couples, we individually have different gifts and abilities. Over the past seventeen years, we have worked hard to separate our duties and responsibilities accordingly to insure the highest level of service. I have always had a passion for helping people in need, so the transition into Real Estate wasn’t difficult. 




After graduating in 2002 from Chico State University, with a degree in Media Arts, I became an integral part of The Stewart Team as a Real Estate Sales Agent.

I enjoy working directly with clients and bring a technology savvy that allows me to see opportunities and react to changes in the real estate market quickly to the benefit of the clients’ desires and needs. I provide them with updated values of the market and comparable properties to insure confidence in their search to ultimately find a property that meets their needs and/or sell their home and identify a new home. 

Working closely with my parents, the combination of strong technology skills along with experience in making and keeping deals together result in a positive transactional outcome for our clients!

I enjoy taking on challenges and serving the needs of all our clients, both Buyers and Sellers. My devotion, communication and technological background serve our clients with the advantage of knowing what to expect and where the market is heading, maximizing sellers dollars and making the transactions a smooth process.

"We recently worked with Bill, Nancy and Sean selling our home in Novato and couldn't have had a better experience. We've sold several homes in the past with other agents, and the experiences were always stressful and frankly depressing. The Stewarts listened to our concerns and absolutely took them to heart, and they never waivered from what we wanted and how we wanted to approach our sale. They even assisted us with many aspects to help us prepare our home and move which were so helpful. Their sage wisdom and long-time experience in the Marin real estate market was extremely valuable in helping us strategize and market our home. We sold and closed our home in record time at a price at which we were happy. The Stewarts all work together seamlessly, and communication was above and beyond our expectations throughout the process. We highly recommend the Stewart Team and know that you will love working with them and will not be disappointed."
