We are TESC.
We are READY.
We are here for YOU.
The milestones in TESC’s storied journey toward becoming one of the most trusted providers of Integrated Construction Services.
Tom Lachance and Stan Huchenski started it all with their maiden project in Elliot Lake at Denison Mines, not far from Sudbury Ontario, the city they called home. These courageous individuals saw opportunity, demonstrated passion, and possessed a vision to succeed.
Now a thriving company, TESC expanded beyond their Sudbury roots with satellite offices in Ottawa and Thunder Bay. Stan’s sudden passing in 1985 cemented Tom’s dedication to carrying on and building a legacy organization.
While many companies had faltered during the recession, TESC was growing into one of the most esteemed contractors with a reputation for excellence in serving the mining industry. The acquisition of a large portfolio from a mechanical contractor gave TESC both skill and scale.
A transition in ownership to Dario Zulich in 2000 marked a transformational chapter for TESC. That same year, TESC became ISO quality certified which set them apart as it was not the standard at the time. This was reflective of Dario’s entrepreneurial spirit and vision for growth through excellence and partnerships. As a local real estate developer, and son-in-law of original founder Tom Lachance, Dario inspired a new generation of talent. This included opening a satellite office in Saskatoon to serve the growing industrial market.
40 years after incorporating, TESC had cemented itself as a multi-trade construction services provider, with expertise far beyond mining and shutdown services. TESC offered value and efficiency as a single-source contractor for industrial, commercial, and institutional (ICI) sectors, working across mining and metals, energy/power generation, and forest products.
In 2020, after 20 years with the company, Julie Zulich became president of TESC. She picked up the baton as the world was entering a global pandemic, successfully steering the company into alignment as to how TESC would continue to make its mark. This included the creation of an advisory board composed of industry greats, investing in deeper professional development and retention programs, and kicking off a collaborative approach to aligning operations around client service and efficiency. Sudbury now became the head office for all national operations.
President & CEO, Julie Zulich, is a strong promoter of diversity in the industry. As the daughter of founder Tom Lachance, she is dedicated to creating the third generation of TESC. Meanwhile, the team continues to build a reputation of experience, confidence, and trust by identifying and addressing clients’ project issues as their own and providing practical solutions to complex construction challenges.
TESC is a people first organization.
Always has been, always will be.
