My career began with 10 years as a Tax Manager, where I gained a deep understanding in personal and corporate taxes. I then expanded my horizons with 8 years as a Senior Financial Advisor at TD and Scotiabank, where I excelled in investment management and Client relationship development.
My diverse experience in both accounting and financial advisory enables me to bring tax strategies that help protect Client's wealth and help them reach their financial goals.

Domenico Colussi
I’ve worked in the financial services industry for the last 20 years, providing ongoing support to help Clients achieve their lifetime financial goals. To better serve my community, I’ve attained the Chartered Life Underwriter ® (CLU ®), Canada’s Premier designation on Wealth Transfer and Estate Planning and the CERTFIED FINANCIAL PLANNER ® (CFP®), an Internationally recognized designation for excellence in Financial Planning. This confirms my commitment to our industry in providing the highest level of support through encouragement, honesty, integrity, and motivation. I’m always working to align stars amongst advisors and take charge in active financial planning support for the best interest of Client communities.
In my spare time I love coaching my kid’s sports, family dinners and end of the night dance parties with my kids before bedtime. I enjoy swimming in the summertime and hitting the slopes in the snow.
My vision is clear in wanting what’s best for Clients by making sure their plans count! I’m a huge motivator and strive at becoming better each day. I’m a proud husband and father of five and look forward to being your value-added business planning partner!
