With more than 34 years' experience managing client portfolios, Randy is a fee-based wealth advisor committed to providing a proactive investment management process for clients. This process includes defining client goals, values, and tolerance for risk and then creating a definable risk management plan. The use of technical analysis is a discipline that defines when to be fully invested, or, more important, when to reduce exposure to the equity markets. This level of commitment is why clients truly understand and believe that Randy has their best interests at heart. His ongoing priority is to create a level of performance and service that exceeds client expectations.
Randy began his career with E.F. Hutton & Company as a financial advisor in Tucson, Arizona, recognizing the many changes taking place within the financial services industry. Randy joined Dain Rauscher as vice president in 1992. He made the decision to move his family back home to Wisconsin in 1999, where he is the founder of MainStreet Investment Group LLC.
He is a wealth advisor with Commonwealth Financial Nework®. As an independent fee-based wealth advisor, Randy selects only those investment opportunities that are appropriate to his clients' best interests.
Randy and his wife, Lollie, reside in Tomahawk, Wisconsin, and have three sons, Brody, Jason, and Cory, and two grandsons, Landon and Jordan. Away from the office, his interests include spending time with his family, bow hunting, and fishing.

Randy and Lollie’s pets bring a lot of joy to our office with their tails wagging as they go from office to office to get their ears scratched and their occasional bursts of energy with their toys. The doggies delight in greeting our clients when they arrive with the opportunity for extra petting sessions. Maggie and Lucy aren’t always in the office, but visit from time to time and enjoy their naps on Randy’s couch whenever they can.
