Summer Sproston

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 everyone in the office, 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 joined the company in 2007 following several years in retail sales, along with promotional work for Clear Channel Radio.  Summer recently passed the Series 7 and is transitioning into sales.
