Our Team

George Byykkonen - Investment Representative


George has been providing investment advice and financial services to individuals and businesses in Platteville and the surrounding area since 1996. Having been in the investment field since 1990, and specializing in helping his clients work towards their retirement goals, he is able to provide them the guidance they need to pursue the retirement of their dreams.

George has earned numerous awards over the years. One of my most recent was Most Valuable Rep of the year for 2011, awarded in early 2012, from Bankers Financial Systems Network of Madison, Wis. The criteria for this award is based on overall production, positive attitude, client service, office efficiencies and his commitment to conducting ethical business with LPL Financial.

George currently lives in southwest Wisconsin with his wife Diane and two children, Ashley and Nicholas.
