About Di Tommaso Law

Di Tommaso Law is a sole practitioner firm, operating as Michael Di Tommaso Law Professional Corporation, based in St. Catharines in Ontario's Niagara region. Its founder, Michael Di Tommaso, earned a Juris Doctor from the University of Ottawa, graduating on the Dean's List, and completed articles at a law firm in the Greater Toronto Area. From there, Di Tommaso moved in house as legal counsel at a publicly listed, multinational technology company and was promoted to chief executive officer within three years.

That corporate background now shapes the firm's client side practice. Di Tommaso Law handles residential and commercial real estate transactions, business formation and contract work, including shareholder agreements and business to business agreements, and estate planning, covering wills and powers of attorney for property and personal care. The firm also offers notary public services, including administering oaths and affirmations and certifying true copies of documents. Its office is on James Street in downtown St. Catharines, and the firm serves clients across the Niagara region.
