About Our Firm
Roots Dating Back to 1939
Our story began in 1939, when Joseph Buska Sr. opened Buska & Buska Insurance in the basement of his Mosinee, Wisconsin home, guided by a simple belief: helping people understand their options can change their lives. That spirit of service became the foundation of a family legacy spanning four generations. Inspired by the example set by her father and grandfather, Sue Buska followed in their footsteps and, in 1992, established her own firm in Wausau focused exclusively on retirement income planning and client education. What started as a passion for helping individuals prepare for retirement has grown into a trusted planning practice built on relationships, experience, and personalized guidance. Today, alongside her children, Cole Bruner and Kailey Berendsen, the next generation continues that tradition — combining decades of wisdom with a forward-looking approach to help families plan with clarity and confidence.
