Summer Sproston

Partner/Registered Service Representative

Summer’s lively nature creates a welcoming environment in the office. Because she is drawn to a wide span of subjects, she excels at multi-tasking and becoming familiar with the numerous aspects of the finance world. Her strong communication skills make it effortless for Summer to work with both clients and fellow employees. Due to Summer’s interest in community involvement, she appreciates the company’s support of community service needs. She often partakes in many of these activities herself as a participant or volunteer.


Summer knew early on the finance industry was where she needed to be. In 2007, following several years in retail sales, she jumped at the opportunity to join Maguire Investments as their receptionist. She worked diligently to become a member of the back office support staff, then a licensed sales assistant, and now a managing partner in the firm. She is looking forward to a long, fulfilling career under the Maguire name.
