Born and raised in Montreal, Jennison has been living in the Silicon Valley since 2013, where he is currently LinkedIn's Head of Accessibility Engineering Evangelism. Previously, he spent almost seven years as a member of RBC’s IT Accessibility Team in Toronto.
Outside of his professional pursuits, Jennison co-founded the annual Global Accessibility Awareness Day (GAAD) in 2012. GAAD is an annual, grassroots effort inviting the broader, high-tech community around the world to participate in in-person and virtual activities intended to raise awareness of digital accessibility issues that people with different disabilities face.
Jennison founded Accessibility Camp Toronto in 2011, Accessibility Camp Bay Area in 2014, and helped found the Boston Accessibility Conference and Accessibility Camp L.A. in 2010 and 2012, respectively. These free, day-long events provide a less formal atmosphere for designers, developers, other tech pros, and people with disabilities to come together and discuss digital accessibility issues. He is General Sessions Chair for the largest conference on technology and persons with disabilities, the CSUN Assistive Technology Conference.
Jennison has volunteered with the CNIB, including sitting on their Winston Gordon Award for Technological Advancement in the Field of Blindness and Visual Impairment Selection Committee from 2005 to 2013, serving as its Chair in his final year. Today, he serves on both the LightHouse for the Blind San Francisco’s Board of Directors (chairing their Development and Nominations Committees), and the American Foundation for the Blind’s Program Committee.
In 2012, Jennison was recognized with a Queen Elizabeth II Diamond Jubilee Medal for his contributions to digital accessibility and the community of people with disabilities at large.
