Impact100 Sonoma is governed by an all-volunteer Board of Directors, each of whom is responsible for a particular aspect and function of operation. Board members also chair the committees of volunteers who keep the organization running.  If you are interested in participating on our Board, please contact our Governance Chair, Sally Brian at


Debbe Noto, Co-President 

Debbe spent her 30+ year career in the banking industry with experience in operations, relationship management, sales, marketing and communications. In 2009 she and her husband bought a second home in Sonoma and fell in love with the community. In 2016, Debbe retired and they moved into their newly built home in a neighborhood where several Impact100 members live. Debbe joined Impact100 in 2017 and knows this is where she wants to dedicate her time and energy. In her free time, Debbe loves to read, travel with her husband and is slowly learning to speak Spanish. 

Claudia Sims, Co-President

In 2002, Claudia and her husband bought what was then a second home in Sonoma. As remodeling was completed and work-lives were wound down, it became their full-time residence. Claudia has a 35+ career in welfare casework and employee benefits. As a benefits consultant many of those years, she became quite experienced at preparing or analyzing benefit plan proposals. Little did she know that experience would be useful at Impact 100 Sonoma.
