Strengthening Global Connections

By: Rachel O'Hagan

January offers a moment to pause, reflect, and set intentions for the year ahead, not only for what we hope to achieve, but for how we continue to show up for one another as a community.

At MacLachlan College, our alumni embody leadership, curiosity, and connection across industries, generations, and borders. As we begin 2026, we are proud to share stories, events, and opportunities that continue to strengthen our global alumni community.

Alumni Spotlight: Olivia Zarrillo ’14

From Kindergarten through Grade 12, MacLachlan College was home for Olivia Zarrillo, a place that helped shape her into the confident, people focused leader she is today.

Like many students approaching graduation, Olivia was unsure of her next steps. What made the difference was a community of teachers who recognized her strengths early on. Mrs. Granville encouraged Olivia to explore the human side of organizational strategy, while Mr. Dominato pushed her beyond her comfort zone through public speaking, experiences that Olivia now credits as transformational.

“At Mac, teachers see something in you long before you see it yourself, and they guide you right into it.”
After graduating in 2014, Olivia attended Wilfrid Laurier University, earning degrees in Psychology and Sociology. Inspired by early Mac travel experiences, she later spent time in Fiji and travelled through Southeast Asia, broadening her perspective and understanding of global communities.

Olivia went on to complete her HR education at George Brown College, earned her CHRP designation, and is currently working toward her CHRL. What began as a one month contract grew into a full time role, where she now leads people focused work in on site construction, building culture and strengthening teams.

Her leadership roots trace back to MacLachlan, where she served as Head Prefect, Communications Prefect in Grade 11, and was actively involved in intramurals, floor hockey, school events, and creative initiatives.
