AIM Trimark alumni Geoff MacDonald has joined EdgePoint Capital Partners, the new investment firm started by former lead manager at Trimark, Tye Bousada.

MacDonald joins the team as chief investment officer, said the firm in a release. When Bousada launched EdgePoint, he said he wouldn’t be actively recruiting current Trimark staff. MacDonald left Trimark years ago.

EdgePoint is a wholly owned subsidiary of Cymbria Capital Corp and MacDonald is also a shareholder in Cymbria with Bousada.

Robert Krembil, co-founder of Trimark, is also a shareholder in EdgePoint, the firm recently announced. Krembil is investing through his holding company, Chiefswood Holdings Ltd.

Krembil led Trimark until it was acquired by Invesco Ltd. in 2000.
