About Us

Jim Dunn, President and founder of Stack Modular, was born and raised outside of Edmonton, Alberta, Canada. At a young age, he eagerly ventured outside the borders of Alberta and found himself living in Saskatchewan, Pennsylvania, California, and Africa. His global travels, subsequent university degrees in Civil Engineering & Architecture, and professional career as an engineer all contributed to his eventual arrival into China.

It was in Shanghai, China where Jim created one of the first Wholly Foreign Owned Enterprises (WFOE) owned solely by a Canadian. After having created Stack Modular, Mr. Dunn went on to hire architects, engineers, and project managers from Canada, USA, and China to oversee the procurement, quality, and delivery of modular buildings to the rest of the world.

Evan is a Director on the Stack Modular Board and VP of Design. After graduating from Lehigh University, Evan began his career in California as a designer for an architectural firm specializing in premium custom homes serving clients throughout the West Coast and Hawaii.  He later joined Jim Dunn’s then newly-created international trade business in Shanghai, China. Here he was instrumental in forging relationships with international companies, building in-house departments, managing projects, and directing design & engineering initiatives.  From those modest beginnings grew Stack Modular, a design-build firm specializing in modular buildings for the North American market with projects ranging from high-end modular homes to multi-story resorts. He currently oversees all design operations.

Jon Higgins comes to Stack Modular from Bird Construction, where he spent many years gaining extensive experience and insight from many of Bird’s operations and projects from start to finish. Jon has already provided his modular expertise to several Stack/Bird projects, playing a pivotal role in the execution of rapid construction/modular delivery.

Jon has helped execute more than $100M in modular construction projects, including the award winning Aqsarniit Hotel & Conference Centre in Iqaluit, Nunavut, and a one of the largest modular workforce housing projects in North America at Cedar Valley Lodge in Kitimat, BC.

Jon leads Stack’s onsite construction team throughout North America, facilitating pre-construction, design management, on-site scope coordination, transportation, craning, and overall execution of modular and conventional aspects of Stack’s projects.

He joined Stack Modular in 2014 as Manufacturing Manager, where he organized, established, and improved multiple production plants, successfully completing numerous modular building projects with varying national and architectural standards.

For many years, Chuxing has focused on factory manufacturing processes, quality control, and production cost and efficiency management for modular building projects. He supports safe factory production and uses automated and robotic systems to improve production line consistency and process control as part of ongoing manufacturing improvement. He works closely with design, project, and procurement teams to align manufacturing requirements and delivery.

Before joining Stack, Geoff co-founded a modular building manufacturer in 2010. There he was instrumental in the design, procurement, construction, delivery, and installation of over 300 modular buildings in a wide range of sizes. This extensive industry experience, along with Geoff’s 22 years in business-related leadership roles involving operations, finance, and management, serves him well as Senior Project Manager with Stack.

The remarkable diversity of modular build projects Geoff has overseen has provided him with a great deal of knowledge regarding the challenges and benefits of modular construction. Nevertheless, should project-related roadblocks arise, Geoff rarely takes NO for an answer. Instead, he will proficiently research, discover, and apply a feasible workaround solution to meet the needs of the client. Geoff finds it incredibly rewarding to do all he can to successfully transition Stack’s modular build projects step by step, on time and on budget, from concept to completion.
