About Us

Meet the Team!

Donna Wilson, MS/OD

Co-Director, Board member, VISTA Alum

Donna“My professional experience includes more than 20 years designing, coordinating, and implementing training and development in government, business, and nonprofit organizations. In this I hold an MS in Organization Development and Human Behavior (USF 1998) with a focus on community building,  leadership and team development, conflict resolution, and executive/life coaching.

“As the founding Executive Director of Sierra NonProfit Services, I have developed a local grant funding library, implemented research and grant proposal coursework, written and managed successful grant proposals, and designed nonprofit training and development conferences in collaboration with nationally acclaimed consultants such as Peter Block, Jill Janov, and Tony Smith,PhD., Patricia Elliott,PhD., and master coaches of the Coaches Training Institute in San Raphael, Ca.  My passion is coaching individuals and small groups to build leadership and stronger more resilient teams at work and in community. This is the work I do because, when we as individuals work to our best strengths, our community benefits.

“As a long time resident of Tuolumne County, you can find me in Sonora, California, the area I dearly love; and where I reside with my husband of many years, 2 dogs, 1 cat, a hoot of wild animals and birds, and occasionally our 3 young granddaughters.”

Amy Falken

Co-director, Board Chair, VISTA Alum

“At Sierra NonProfit, I’m the specialist in nonprofit filings and compliance, as well as blending for-profit and nonprofit entities, social-purpose corporations, and fiscal sponsorship.

I love startups and turnarounds, with both for-profit and nonprofit organizations. I bring experience and resources that will point people in the right direction to make money in the best way possible. I like to work with people in the early stages of getting started or making changes, preparing them to enter into what they are doing exactly as they are designed to do. I use a variety of tools to accomplish this, including Strengths Assessments and Human Design, as well as materials from Chris Brogan and James Altucher. Right now, it is vital that we approach life and work with complete authenticity. You are a unique individual, and your gifts are needed.

My background includes many years in I. T. beginning with the first personal computers in the 1980s. Our office at Sierra NonProfit Services is both virtual and physical. I have served as an Americorps VISTA member and Program Manager. I have also started an auto repair shop, a computer service center, a skydiving school, and most recently, opened a coworking center in Sonora, CA with my husband.

I’ve been in Tuolumne County for over 20 years, and enjoy life with my husband, our teenage son, my friendly corn snake, my very cool bearded dragon, and the hummingbirds who visit regularly.

I believe everyone and everything has something to offer, and everyone has a right to be invited to the table.”
