Brian Miller

Brian Miller

Advisor

Brian served in the US Army for eight years, spent 15 years in law enforcement after the military while also serving his community as a volunteer firefighter. He has dedicated a majority of his life serving his country and community. He is a dedicated husband to his wife of 12 years and four kids. He values God, country, and family. Brian served on the Board of Directors for Circles Green Bay through Green Bay Community Church.  In 2013, he and his wife took a leap of faith and started a local ice cream store (Monkey Tailz), which now is a mobile food truck. He is also president of the Green Bay Food Truck Coalition hosting food truck rallies in the summer. Brian has experience navigating the rough waters that come with running a business and has learned more from his mistakes than his successes. He volunteers for the Green Bay Packer Mentor Protégé Program and helps mentor other local small businesses. 

Matt was his financial advisor and eventually became his mentor which led him to become a financial advisor with Cornerstone Financial and Benefits Consulting. Learning the rules of money and how to get your money to work for you was an eye-opening experience. His goal is to teach and guide his clients to meet their financial needs and goals in the most efficient way possible. It does not matter where you are at financially; in debt, saving money, or do not have any money to invest, he still wants to work with you and help meet your goals. If you need health insurance, he can also help you find a policy that is a good fit or if you would like advice reviewing your current policy or picking a new one, he would like to talk. If you are curious about cryptocurrency, NFTs or web 3.0, he can help guide you in that journey also. Brian has been an active investor in the space for six years. Due to regulations, he cannot give you investment advice but can give you resources to get started in your crypto journey or just educate you about the space.  If you are curious about anything mentioned above, Brian would love to talk with you.

Cynthia Leclair

Cynthia Leclair

Advisor

Growing up and working in her parent’s business for many years was a great experience, Cynthia learned so much about business, manufacturing, human resources, sales, and more! It also taught her about what the economy can do to a business or a portfolio, which left her somewhat of a skeptic when it comes to truly achieving financial security until she was introduced to Cornerstone. At Cornerstone they take a different approach, a holistic approach, to help people create and execute a plan to financial security without it costing them any more than they already are spending. That is exciting to her, seeing people’s lives change!

Cynthia is a wife to Alan, a mom to three grown boys, Travis, Sam and John, and a dog mom to Daisy Mae her Chocolate Lab, Border Collie Mix. In her free time you’ll find her leading a Bible Study at their church, planting or caring for her flowers, working out, walking, biking, snow skiing, fishing (for her husband – not for fun necessarily), playing boardgames with friends, helping out her parents, and spending time in the Northwoods.
