Mark Tamminga is a partner in the Hamilton office of Gowling WLG and Leader of Innovation Initiatives for the firm, worldwide. Previously, Mark was Managing Partner of  Gowling’s Hamilton Office. Mark’s law practice centers on real estate law and recovery services, with a focus on mortgage remedies, creditors’ rights and general insolvency. He has particular interest in the area of computer applications and the design of software tools for lawyers.

He is a former Chair of ABA TECHSHOW and a frequent author on practice management and technology issues.

Mark earned his MBA/LLB in Law and Business from York University – Osgoode Hall Law School in 1986.


Mark Tamminga – Mark is … well different. Most of us are still slaves to the billable hour. Mark built a massively profitable automated collections and mortgage system – and hasn’t even glanced at the clock for a decade. It’s a money machine running on code.

Most of us go on holiday and send a few postcards. Mark’s the sort of guy whose travels are tracked by the New York Times Travel Section. He was last year’s world champion in the Atacama Desert Crossing. That’s a 160 mile race over a six day period, at least a mile above sea level in an unforgiving lunar landscape that is 50 times more arid than California’s Death Valley. The temperature swung up and down sixty degrees, starting below freezing. As I said, this dude is different.

And – just as he does in the wilds of the globe – he succeeds in accomplishing innovation in the business of practice of law – and in his willingness to contribute ideas and energy. If there were “Extreme Law Practice Management” games, Tamminga would be at the top – feet taped into his boots to prevent sand getting in and pulping feet to bloody stumps.

At ABA TechShow – which he chaired – and through his amazingly prolific contributions to Law Practice Magazine, as well as the fascinating new model he has created for his own firm, Mark has shown himself to be committed to blazing new trails, undaunted by the tribulation others fear.

Mark, welcome to the College.
