Muguette Guenneguez


Muguette is a 20-year Seattle resident with a passion for children, education, social justice and mental wellness. She was born in Haiti; her family moved to New York City when she was a teenager. Her family was deeply impacted by members with mental illness. She believes the best way to eliminate stigma is to have honest conversations about mental illness.

For the past 15 years, her work has centered around education, social justice and advocacy.

She has served on the board of several organizations including Launch, the largest before and after school program in the Seattle area, and Ventures, a microenterprise organization inspired by the Grameen Bank of Bangladesh. In addition, she served as co-chair on the Equity and Inclusion task force of Seattle Academy of Arts and Science, and founded and directed Learning Assets Tutoring Services, helping young people develop a lifelong commitment to education and learning.

In 2018, she dedicated herself to a project called Common Purpose, a citizen activist pipeline where participants learn the nuts and bolts of voter registration, engagement and mobilization. Muguette is a proud community advocate for equity in education, housing and health care.

She graduated from Seattle University with a degree in International Business. She enjoys living in the Northwest with her family and friends. In her spare time, she reads, cooks and volunteers.

Maddy Noonan


Maddy wrote a paper titled “We’re All Mad Here: The Manifestations of Mental Illness in Theater,” and briefly speaking that is how her background in performing arts and marketing brought her to NAMI Seattle. The arts and mental health have quite a lot in common; this is why she has a tattoo inspired by Robin Williams, and why she has been a guest blogger for Mental Illness Happy Hour. Her insistence on diversity, inclusion, and accessibility cannot be diminished. It is paramount to Maddy that we are all, regardless of the demographic information or socioeconomic status, able to receive the support we need to live exhilarating abundant lives. When she’s not at NAMI, Maddy can be found at theaters around town (including Copious in Ballard) or at the dog park.
