David Mothus
I began my career in financial services because of a love of helping my friends with their finances. This has expanded as I have taken the time to get designations. I have the Certified Divorce Financial Analyst designation and the Certified Executors Advisor designation.
Serving as an advisor since 2011, I specialize in assisting Clients with:
- personal and corporate wealth building strategies,
- insurance protection strategies and
- retirement planning.
I work tirelessly to provide Clients with the knowledge, guidance and motivation to help them fulfill their plans. I give Clients peace of mind, because they know that I will help them take care of their family and future.
Outside of work, I volunteer with Junior Achievement BC, a non-profit organization that teaches financial literacy to local youth. I am on the board of the Tabor Lake Cleanup Society and the Blackburn Community Association. When I’m not busy with these associations I spend time on the lake and snowmobiling. I enjoy spending time with my two dogs and my beautiful partner, Tanya.
