Ann Thalman, Treasurer

Ann has been leading teams in tech and finance for over 20 years, and especially enjoys helping individuals and teams find their peak performance, while operating in the most efficient manner.  Ann was COO and Sr. Vice President of Infrastructure of Baker Street Advisors, a private wealth management firm in San Francisco, for 11 years,  where she was responsible for operations, reporting, HR, IT, facilities, compliance, finance and administration, during rapid growth.  In previous roles at Autodesk, Oacis Healthcare Systems and Alta Bates Summit Medical Center, Ann led teams that implemented and supported clinical systems, as well as technical writers.  Ann has a BBA in Finance from Kennesaw State University and a MBA in Strategic Leadership from Dominican University.

Ann is married with a son and daughter, and when not attending a Sunflower Wellness exercise class enjoys digging in her garden, cooking and hiking the hills of Lucas Valley.

Ann is a cancer survivor who believes that Sunflower Wellness' exercise programs restored her strength, confidence and dignity.  Her role as Treasurer started in the Fall of 2018 and she is delighted to giving back to an organization that helps its members living with cancer.


Carrie (Bonnet) Tichenor, Director

“This program was my magic pill,” says Carrie, who works in communications management as Media Relations & Marketing Director for the law firm of Rains Lucia Stern St. Phalle & Silver, PC, and formerly served as controller in her role as human resource business partner for a multi-location retailer. A cancer survivor herself, she says: “Even if I’d been lying on the couch for days after treatment, I always made it to my planned exercise sessions because I knew I’d feel exponentially better afterward and until the next treatment. That helped me regain my sense of control.”

Carrie was thrilled to accept Sunflower’s invitation to become treasurer, a role that she held from 2009 to 2017. “Demand for our service is much greater than when I was a client and we’re growing rapidly to meet it. Cultivating income streams to support that growth may be our biggest challenge,” she says. “I want to make sure as many people as possible can benefit from our exercise program. Because my workouts improved my physical state, they boosted my attitude. When you’re sick and your prognosis is uncertain, a positive attitude can save you.”

An avid traveler (with a special fondness for India), Carrie was born and raised in Marin County. She received a B.A. in Communication from the University of California, Santa Barbara and a master’s degree in Communication Management from the University of Southern California. As a graduate student, she examined the impact of professionals donating their skills to nonprofits (People Assisting the Homeless/PATH, Jewish Big Brothers Big Sisters of Los Angeles) via virtual tools and teams. Carrie is also a mosaic artist.
