Jeff Rotmeyer
Founder & CEO

Originally from Vancouver, Jeff came to Hong Kong in 2005 for a teaching position in a Hong Kong public school. Soon after arriving Jeff got involved in charity work and was introduced to the homeless population in Sham Shui Po. This meaningful evening was an eye-opener for him and evolved into monthly - and now daily - visits to give food to the homeless community. He founded ImpactHK in 2017 and thanks to the support of thousands of caring volunteers, we have collectively made a huge impact for those experiencing homelessness in Hong Kong.

Jeff is passionate about standing up for marginalised communities who are typically held back and unfairly judged. He is dedicated to serving people who are homeless in Hong Kong and sees his role as an enormous privilege.
