Founded in 1981, GGFI Law LLP is a diversified general practice firm that represents both individuals and companies across many areas of law. Its work runs from adoption, family law and wills to real estate, corporate and charity law, civil litigation and estate administration. Over the decades the firm grew steadily to nineteen lawyers and forty staff, and clients can meet them in Kitchener, New Hamburg or Waterdown.
Karin Maiterth, a partner who heads the estate administration department, had completed five years as managing partner by 2025, the same year that marked two decades with GGFI. Partner Mark Radulescu leads the litigation department.
Several of GGFI's lawyers came up through the firm itself. Robert Lanteigne started there as an articling student, became an associate in 2015 and made partner in 2021, while Carly Bauman and Megan Kish both worked at GGFI as summer and articling students before coming on as associates in 2020 and 2025. Today's students go to arbitrations alongside the firm's barristers and carry their own Small Claims Court and Landlord and Tenant Board files.
Ted Giesbrecht started the firm in Kitchener on April 15, 1981, with one lawyer and a single secretary. Warren Griffin joined Giesbrecht's practice after being called to the bar in 1983, and Stephen Funk came aboard in March 1991, when the firm was known as Giesbrecht, Griffin.
Several other practices have also joined the firm. Fred Heimbecker came over in October 2016, ahead of retiring, so every one of Heimbecker's clients would have a smooth transition. The firm of Haney, Haney, and Kendall joined on July 2, 2019, Colleen J. Winn's practice followed on October 3, 2022, and Amy, Appleby, and Brennan came over on January 3, 2023. That Waterloo firm went back to 1977, when Bill Appleby joined David Amy and Peter Brennan to form it, and Amy and Appleby both retired from GGFI effective December 31, 2024.
Giesbrecht retired on December 31, 2023, after forty-three years of practice. The founder's adoption work reached well beyond Canada, to countries including Guatemala, Ukraine, Ethiopia and Haiti.

GGFI has over 25 years' experience helping business owners plan how to hand off or step away from their companies. Mark Radulescu acts for franchisors, from setting up a franchise system and drafting disclosure documents and agreements to enforcing franchise rights, and Gurminder Singh's corporate work includes medical professionals and other professional corporations.
On a purchase, the firm runs a preliminary title search as soon as the agreement of purchase and sale arrives. It deals with secondary financing such as vendor take-back and private mortgages, and handles transfers of title between spouses and relatives, including the paperwork, registration and tax advice. Martin Mahlstedt handles complex commercial real estate deals, commercial financing, leasing and the oversight of land development.
GGFI acts for people and companies that supply materials or services to property owners. If a supplier isn't paid, the firm prepares the notices and registrations that go on the owner's title and then takes the matter through court to collect what's owed.
Every will at GGFI is drafted after a detailed conversation with the client and shaped to that client's circumstances. For estate trustees, the firm can prepare and file the Certificate of Appointment application to the Ontario Superior Court of Justice, and how much it takes on depends on the help the trustee wants.
Whether it's a simple divorce or a complex support and property dispute, the family team commits to offering a range of options and working in a timely, cost-effective way. Its lawyers have advanced training in Collaborative Family Law and have acted at all levels of court in Ontario. Joseph Irvine practises family law only and has wide experience with collaborative law, mediation and mediation-arbitration, processes that can help keep costs down and preserve a degree of civility.

Adoption is one of GGFI's own practice areas. Karin Maiterth handles step-parent and relative adoptions, and the firm processes step-parent adoptions anywhere in Ontario.
GGFI works with churches, charities and not-for-profits on incorporation, changes to their structure, charitable registration and partnerships with other groups in Canada and abroad. Nigel Haykin's practice focuses in particular on charity and not-for-profit law at the federal and provincial levels, and Warren Griffin has worked with charitable organizations from their formation onward.
Mark Radulescu's litigation covers employment matters for both employers and employees, estate disputes, defamation and franchise litigation, among other areas. In May 2022 the Waterloo Region Record featured Radulescu after a judge awarded damages to a client who'd been defamed online. Jennifer Mohomed-Indarsingh brings experience in estate and power of attorney litigation, employment and contract disputes, and negligence.
GGFI launched a full-service immigration and refugee law department in April 2024, with clients ranging from individuals and families to small businesses and large corporations. For employers, it helps bring in temporary foreign workers when labour is short, move staff temporarily to a Canadian branch, and get the authorizations needed to start a new business venture.

By appointmentAt GGFI, service comes first, and building and keeping a relationship of trust with clients is the firm's guiding priority. As a community-minded firm, it looks for lawyers who value service and enjoy forming long-term relationships with clients and the wider community.
The Kitchener office is in Suite 200 at 515 Riverbend Drive. Kitchener sits at the centre of Waterloo Region, about an hour by car from Toronto, and the region is home to the University of Waterloo, Wilfrid Laurier and Conestoga College.
In New Hamburg, the office is at 82 Huron Street, Unit B. Stephen Funk grew up in the New Hamburg area. The village was first called Cassel and took its new name from German settlers in the mid 19th century. Wilmot Township designated the historic core as the New Hamburg Heritage Conservation District in 1992, and the district's Hartman Bridge carries Huron Street over the River Nith to Waterloo Street.
The Waterdown office sits at 95 Hamilton Street North, Unit 5, and Robert Lanteigne divides time between clients there and in Kitchener.
