About Us
Beyer & Rock Investments has been proudly serving the Quad Cities Area for over 70 years!
Your money is important! That's why chosing someone trustworthy to manage it is equally important!

Beyer & Rock Investments boasts an experienced and knowledgable staff whose main mission is to help you meet your financial goals--whether that is saving for retirement, saving for college tuition, growing your net worth, or protecting your investments! Instead of being tied to certain funds or companies, and only pushing those, we have a full range of options, and vow to always customize your portfolio based on the best fit for you.

We are a family owned, local business. While we have a small, close-knit team, we're proud to possess the same capabilities of a large national firm, but with personalized hometown customer service and a year-round committment to you!

Beyer & Co. was founded in 1946 by John M. Beyer, Sr.  His son, John (Jack) M. Beyer, Jr. , joined him after graduating from St. Ambrose Academy.  Kerry Beyer and Amy Phillips, Jack's son and daughter, joined the family business in 1985 and 1998, respectively.

Dean Rock, who joined Beyer & Co. in 1982, became a partner  in 1999, and the company officially changed it's name to Beyer & Rock Investments in 2004. Dean's son, John Rock, joined the business in 2016.  The business now has multiple generations of service in the QC Area within the Beyer and Rock families.
