MEET OUR TEAM

Alison Cebulla, MPH
Founder, Consultant

Alison has a background in nonprofit management, grassroots organizing, volunteer management, 1:1 and group coaching, emotional intelligence, interpersonal trust and communication, and Adverse Childhood Experiences (ACEs) science education. She worked in the Fair Trade industry, which seeks to end violence against women through economic empowerment, from 2011-2013 and 2015-2017, trying out the tech industry in 2014. Concurrently she launched a health coaching business to help people develop emotion management skills for better health, teaching the popular Give Up Sugar for Good Program from 2017-2019.

Her work as a health coach led her to realize that Adverse Childhood Experiences are barriers to people attaining their health goals—the same realization the original researchers had when their weight loss intervention failed—leading them to ask deeper questions about childhood trauma and publish their findings in the landmark 1998 ACEs paper. This led Alison to go back to school for an MPH to work in trauma prevention.

She has worked professionally with trauma experts such as Dr. Bessel van der Kolk, Dr. Gabor Maté, Dr. Ed Tronick, and more as the producer of live events at PACEs Connection (2019-2022).

She holds a BS in Conservation and Resource Studies from UC Berkeley (2009) and a Master’s in Public Health from Boston University (2019). She received her Health Coach Certification in 2014.

Alison runs the Kind Warrior blog and social media accounts to promote kind living that includes environmentalism, feminism, anti-racism, and systems of oppression literacy. She hosts the Latchkey Urchins & Friends podcast, which is in Season 3, that heals trauma with humor.

Alison has lived experience with severe mental illness, namely Major Depressive Disorder, and is in recovery from Substance Use Disorder. She’s especially passionate about implementing trauma-informed care in psychiatric and substance misuse rehabilitation programs and facilities. In 2014 she lost her cousin, who was a best friend, to substance misuse-related suicide and in 2022 she lost a beloved ex-partner to a fentanyl overdose.

”It’s not trauma-informed if it’s not informed by trauma survivors.” - Cissy White (1966-2023)

Marianne Avari, MPA, MS
Advisor

Marianne has worked in the public and nonprofit sectors for the majority of her career. In each of the positions she’s held, she noticed the same reoccurring problem: trauma-informed people-operations practices put in place in the workplace were antiquated or nonexistent. 

In addition to her regular job duties, Marianne used her assessments of workplace cultures to volunteer to create employee engagement events, advocate on behalf of staff to update policies and procedures and facilitate healthy communication among departments and teams. 

Marianne recognizes that many workplaces are not currently equipped to handle the ever-changing and different needs of a multi-generational workforce. It is through her organizational assessments and recommendations that gives rise to healthy and empathic satisfaction among leadership and staff. 

Marianne graduated from Johns Hopkins University with a Bachelor of Arts in Psychology. She also holds dual Master's degrees from the University of Pennsylvania in Public Administration and Criminology.

In her free time, Marianne is a reality T.V. enthusiast and dog mama to her chihuahua, Squirrel.
