“Undiagnosed” -Alex Yiu’s Journey

We are thrilled to share with all of St. Mark's Parish an exciting update from the filmmakers who have followed and filmed Alex’s journey for 9 years! The world premiere of the documentary film "Undiagnosed" will take place at the 38th Boston Film Festival in Boston, Massachusetts 22-26 Sept. 2022. You can view the film festival trailer link and access tickets to the virtual viewing of "Undiagnosed" at the Boston Film Festival.

“Undiagnosed” film also has been accepted at 8 other upcoming film festivals around the world. Please visit the film website


We are honored to be part of this project to raise awareness of those who suffer from debilitating illness without a diagnosis.

We hope this film will instill an urge for people to take action and help change the future of medicine.

Thank you for years of support, love and prayers.  -Caroline
