ACS Team
We serve those who serve

“Every one of us is tenacious and dedicated and hard working. Yet we are also giving and loving and passionate. At Asian Charity Services we know we are building a stronger society supported by the professional leaders serving at NGOs across Hong Kong”.

Asian Charity Services is powered by a core team of staff, both paid and volunteer. Their drive and determination bring our workshops to life with detailed planning, expert content, well-matched volunteers, and all the right NGO leadership teams represented. We have a small office in Wan Chai where we lead operations.

Over the past decade we have learned that our team members are with us for a reason, a season or for life. Some are needed for a specific project or program (a reason). Others make a longer-term commitment and support a number of projects (a season). And some have dedicated a portion of their life and career to making Asian Charity Services a success (life). For each person’s contribution we are deeply indebted and very grateful.

Thank you from Asian Charity Services.
