About Us/关于我们

Our Story

We are a group of experienced professional health care providers in Calgary. As first-generation immigrants from China, we have a profound understanding of the special challenges and barriers facing senior immigrants and would use our expertise to help them access resources for their retirement.

We founded a non-profit organization “Happy 50+ Association” in 2018. We have been running many free activities for Chinese immigrants over 50 living in Calgary and any Calgarian who wants to plan his/her retirement life in advance.

Since 2018, approximately 8000 Chinese Calgarians have attended over 20 in-person seminars organized by Happy 50+ Association. Please see Appendix A for the highlighted services and workshops.
