Our History

In 1972, after finishing a commission of service in Vietnam as a Naval Lieutenant and Commander of a US Swift boat, Dennis McGuire, Sr. began his now long-standing career in the world of investments and finance. As a graduate from Providence College with a Bachelor's degree in History, Dennis was hired as a broker with Merrill Lynch in Providence, RI. An investment advisory practice was born, which continues to this day. From the very beginning, an above-all focus on the client was the basis of his approach, coupled with a unique and talented search for truly great investments, with tailored recommendations suited to individual investor’s needs.

Over the next 30 years, Dennis successfully built his practice, taught investment classes, wrote numerous investment articles, with knowledge and expertise gained through employment experiences at Merrill Lynch, White Weld & Co., Drexel Burnham & Lambert, and A.G. Edwards & Sons, Inc.

As a graduate from a full 4-year academic scholarship from the University of Rhode Island with a Bachelor of Science degree in Microbiology and Chemistry, Dennis’ son Denny joined his father in early 2001 after working in the field of Vector-borne illness research. In 2008, Sean McGuire joined the practice, after graduating from the University of Rhode Island with a Bachelor of Science Degree in Finance. Together, and working as an advisory team for their clients, in 2009 they formed McGuire Investment Group, LLC of Wells Fargo Advisors Financial Network, and became an independent advisory practice.

In 2018, McGuire Investment Group became a Registered Investment Adviser (RIA) with the Securities and Exchange Commission. In solidifying their independence and fiduciary role, a new chapter had begun, one constantly improving with access to institutional research, dynamic portfolio management tools, high-quality trading, and custodial services, as well as cybersecurity and investor protection enhancements.

Our history will continue to be written. More importantly, we are honored to be a part of each client's history, as well as their future. We strive to offer the best wealth management and investment advice possible while still relying on the fundamental principles of Dennis Sr. developed since 1972. Our history is our path to the future. We will do our best job for you.
