Hospitality Service & Training Excellence 

About Us

ServiceMastery is a hospitality service training and consulting practice dedicated to helping restaurants, Cafes, steakhouses, hotels, and food and beverage operations raise their service standards with clarity and consistency. Based in Oakville, Ontario, we work with hospitality businesses across the GTA and Ontario to strengthen guest experience through structured training and practical service systems.

Our work is grounded in real hospitality operations. We understand the pace, pressure, and expectations of live service, which is why our approach focuses on floor-ready execution, not theory. Every program is designed to support service teams where it matters most - on the floor, during service, and in real guest interactions.

ServiceMastery provides customized solutions including hospitality service training, customer service training, food and beverage technical skills development, standard operating procedure (SOP) creation, and mystery shopping audits. Each engagement is tailored to the client’s service style, brand positioning, and operational flow to ensure standards are practical, achievable, and sustainable.

We work with steakhouses, fine dining and casual restaurants, fast-casual concepts, hotels, cafés, and service driven food operations, supporting both new openings and established teams seeking greater consistency and professionalism.

At its core, ServiceMastery exists to help hospitality teams deliver service that feels polished, confident, and intentional - shift after shift, guest after guest.
