Finding Charles Cullen and his team early in our process of immigration was critical for managing a relatively seamless transition in what was a highly complex process. We are in good hands!

—Charles S. and Nancy S.

When I moved from Canada to the U.S., I had different savings and retirement funds in both countries. I had multiple investments and savings with different institutions with no strategy for retirement. The team consolidated my various accounts and have been able to grow my savings and provide me with clarity on my financial health and financial future.

—Maurita B.

We planned to repatriate to Canada and needed assistance amalgamating our U.S. and Canadian investment portfolios. Charles Cullen and his team were invaluable in helping strategize how and when to move our portfolios to RBC Dominion Securities. He has been instrumental in making our transition back home so seamless.

—Kate S.

Charles, John, and Morgan have served as excellent advisors and stewards during many changes in my life. I recommend them completely.

—Noel T.

From the first call we had with Charles, I had a solid impression that he would provide the kind of management and direction I hoped we would find. Since that time, the RBC team has well surpassed our expectations in terms of communication, availability, review and planning, investment returns, and income tax savings.

—Carol C.

Expert knowledge of cross-border investing and a platform to invest in both Canada and the U.S. were the reasons why we chose this team. Charles Cullen, John Donaldson, and Morgan MacLean are the most knowledgeable, responsive, and understanding team that my wife and I have ever experienced.

—Kevin and Flora P.

To say we sleep better at night because of Charles and his team would be an understatement. We believe having a trusted advisor, as we do with Charles, has made our retirement far less stressful, and we can’t thank him enough for what he and his team do for us.
