Chuck Magyar, David Lyon, and Stewart Istvan are the creators and owners of Watermark Stone Wealth. They first met when they were shorter and had more hair.

Royal St. Georges College brought the trio together during their high school years. In 1984, they journeyed to London to attend University of Western Ontario where each earned a BA in Economics. After graduation, they went their separate ways until May of 2005, when they reunited as partners of the Forest Hill Branch of HollisWealth (then DundeeWealth).

As the business grew, they formed a strong team of investing, planning, and insurance specialists; this collective is now Watermark Stone Wealth.

Dealing with the team at Watermark Stone Wealth allows me peace of mind. With all of the global financial market instability, it is comforting to know that Chuck, Dave, Stewart and Kate are at the helm allowing me to rest easy and stay focused on the longer term outcome. They are available to take my call whenever I have a question and their proactive approach to market conditions has always been of value to me. My investments, while important, are only one aspect of the overall plan.
