About TTG Law

TTG Law is a solo practice in Guelph, Ontario, run by Teresa Tummillo-Goy, who has practised law for close to 30 years. The firm's main work is residential and commercial real estate, from purchases and sales to mortgage financing, and it acts for vendors, purchasers, and lenders, including on private mortgage deals. Alongside the real estate files, the practice prepares wills and powers of attorney, handles estate administration, and offers notary and commissioner of oaths services. It's a small, personal office, one that describes treating clients as people rather than as files.

The founder's path runs through two cities. Tummillo-Goy began practising in Kitchener, spending roughly 15 years there on a broader mix of work that included litigation, debt enforcement, construction lien files, bankruptcy and insolvency, and family law. The practice moved to Guelph in 2011, a return to the city where the founder grew up and completed an undergraduate degree at the University of Guelph. Today the firm serves clients across Guelph, Kitchener-Waterloo, Cambridge, and Toronto.

The neighbourhood

The office sits on Edinburgh Road South, a west-side Guelph street a short drive from the downtown and from the University of Guelph campus where the founder once studied. That local connection is real. The move to Guelph in 2011 was a homecoming, and the firm's roots in the city go back well before the office opened. The location also suits the work. A real estate practice depends on reaching clients across a wider area, and the Hanlon Parkway ties this side of Guelph to Highway 401 and to Cambridge, Kitchener-Waterloo, and beyond, the same corridor where the firm's buyers, sellers, and lenders tend to be.
