Steve Gannon opened the Gannon Insurance Agency in August, 2000. Opening the agency gave Steve the opportunity to use all his prior education and training to help the people in his community obtain the best insurance products available at the best price.
Steve is a graduate of St. Joseph's University where he obtained his bachelor's degree in finance and later his Masters in Business Administration.
Prior to opening his own agency, Steve worked for Prudential and Cigna as a Property and Casualty Claims Adjuster. He held the position of Registered Representative at New York Life Insurance where he sold life insurance and financial products. He also sold auto, homeowners and life insurance for Allstate. Steve has worked both ends of the insurance business–as a company man and currently as an advocate for his clients. That's what makes the decision to buy from the Gannon Agency a great decision–you obtain access to years of training, experience and wisdom. Steve Gannon is truly an expert in his field!
