About Andriessen & Associates

Andriessen & Associates is a business law firm on Evans Avenue in Toronto. Managing lawyer Inga B. Andriessen, a graduate of Osgoode Hall Law School, was called to the bar more than 30 years ago and has practiced exclusively in business law since founding the firm in 1993. The firm still runs on an idea that goes back to that start: most of its non-litigation work, including incorporations, shareholder agreements, and employment documents, is billed as a flat fee, so business owners know the cost before the work begins.

The practice covers a wide band of business matters: collections and Small Claims Court cases, commercial leasing for landlords and tenants, corporate formations and reorganizations, equipment leasing disputes, and employment law, where the firm represents employers rather than employees. Associate Robin K. Mann, a University of Ottawa law graduate, joined the firm in 2018 after starting out in family law. Associate Ariel Dorfman, an Osgoode Hall J.D. with a finance background, joined in 2024. A licensed paralegal and law clerks round out the team, handling collections files and corporate filings.
