CEN Staff Members 


Larissa Robideaux, MPA

Chief Executive Director

Larissa has an extensive background in the nonprofit sector and a true passion for leadership development. She is a second-generation nonprofit leader, raised on the philosophy that commitment to quality services empowers the people served and the community as a whole. Her father, Dr. Joseph F. Campbell, spent 40 years as a nonprofit leader and an advocate for individuals with disabilities. Larissa was deeply impacted by his commitment to social justice, education, and human services and has dedicated her life to continuing this legacy. Larissa and her family immigrated from Ireland in 1976 and traveled back frequently. It was this immigrant experience in part that influenced her deep commitment to Diversity, Equity, and Inclusion, and in always striving to represent and give voice to those not always given a seat at the leadership table.

Larissa became CEN’s Executive Director three years ago and has over 20 years of experience in the nonprofit and private business sectors. In her tenure with CEN, along with her dynamic team, and dedicated Board, the organization has almost tripled in size. She has a Master’s degree in Public Administration, an undergraduate degree in Business and completed her thesis on public and private sector partnerships. Larissa has served in leadership roles for organizations that served individuals with disabilities, the autism community, at a community health clinic, and at an organization that served individuals going through health emergencies and crisis.

Larissa currently serves on the Board of Directors for Carry the Vision, a nonprofit in the SF South Bay. Larissa is a graduate of CEN’s Leaders Institute Class IX and was the 2016 CEN scholarship recipient for Harvard Business School’s Strategic Perspectives in Nonprofit Management course. In 2019 Larissa was recognized by the Silicon Valley Business Journal as a woman of influence. Larissa is currently completing a certificate in Change Management from Cornell University and is BoardSource certified. Larissa has been married to her wonderful husband for 25 years and is a proud mother of her two sons, Quinn and Cassidy.

Illyasha (Illy) Peete, MBA

Director of Diversity & Consulting/Training

Illy joined the CEN team in 2018, bringing a wealth of knowledge through her experiences as a transformational nonprofit executive director, corporate trainer, adjunct college professor, and a health and fitness manager (at Stanford Health Care/ValleyCare). She is extremely passionate about self-care and has spent decades working on the prevention side of health and wellness. Additionally, Illy has experience as a real estate professional, with a multi-million-dollar portfolio, which armed her with the ability to market effectively, negotiate contracts, and manage finances. Through all her experience, Illy is most intrigued by partnering with leaders to create work spaces geared at fostering a sense of belonging and believes this is achieved by developing a more sophisticated understanding of intergroup relations and by demolishing the policies, processes, and hiring practices interfering with the values of inclusion, diversity, equity, access, and liberation.

Illy earned a bachelor's degree from Western Michigan University in human resource management and her master's in business administration from Ashford University with a focus in global management.  She also earned a Diversity and Inclusion Certificate from Cornell University and a certification from BoardSource in nonprofit governance and leadership and is a graduate of CEN's Leaders Institute.
