Mountain Law Corporation About Us Peter Shrimpton

Mountain Law Corporation’s founder Peter Shrimpton (now retired) grew up skiing and vacationing in Whistler.

When it came time to settle down and start his family 30 years ago, he knew the growing community was exactly where he wanted to be.

,“I watched Whistler grow and saw that it had a lot of potential as a true community where families could set down roots and entrepreneurs could embark on substantive careers,” Shrimpton says.

“As a young lawyer, wanting to have a large family and desiring an idyllic recreational setting not too far from the urban environment, I decided Whistler would be the perfect place.”

Shrimpton purchased two practices in Whistler and merged them to create Mountain Law Corporation. One was from a retiring lawyer, and the other was a successful notary practice.

From there, he built on the existing clientele with his community involvement.

After almost a decade on the board of the Whistler Youth Soccer Club, Shrimpton served as President for seven years.

He provided pro bono legal advice to numerous non-profits and charities and had for many years volunteered weekly for Whistler Community Services Society’s low-income law clinic in association with Access Pro Bono B.C. In July 2023, he was recognized with a provincial award for his APB service.

He also served as Board Chair of The Whistler Forum for Dialogue and Innovation, the Whistler Village Church, and the Whistler Skiers Chapel (which then became the Whistler Interfaith Society).

Mountain Law’s two-pronged practice focused primarily on wills and estates and business law transactions.

He retired in July 2023 when his associate lawyer Amanda Welton-Hagen took over Mountain Law.
