Sandy joined the agency in 1988 and is the daughter of Joseph Buska Jr. She started working as receptionist and later started doing the accounting for the agency. She continues to do the bookkeeping as well as managing the office administration. She is also a licensed property and casualty agent and works with John in the commercial lines department. She will be happy to help you with your claims, changes and certificates of insurance. In her spare time she enjoys listening to her son’s band, long walks, and spending time with her family, friends and two cats.

Cindy Newman


You could almost say Cindy was born into the family business. She started cleaning the agency’s offices at age 14 when they were located on Forest Street in Wausau. Shortly after high school she started on the insurance side in 1980 helping with filing, clerical duties and claims. She eventually went into sales, building her book of business over the years. Cindy is licensed in property and casualty, health and life. She took insurance and marketing classes through NTC, company and on-line classes. She primarily works with her current clients and with referrals, customizing policies for each individual’s needs. Cindy’s faith is very important to her. She loves her church home, listening to Christian music and going to concerts, painting and decorating and spending time with her family. She has formed many friendships over the past 35 years and truly cares for her clients. She can attest to the Buska motto of “we don’t sleep soundly at night until you do.”

John R. Kasmerchak

Commercial Agent

My friends and clients call me “Kaz.” I have been employed by Buska & Buska Insurance since 1990. I primarily work with businesses and farmers to fulfill their insurance needs. I also sell life insurance. I have been married to my wife, Donna, for the past 27 years. We have two children, Sarah and Chase, whom I’m immensely proud of. I’m also a dad to a boxer named Axel and a cat named Teaky. I adore my two granddaughters “Sweet Pea” and “Schatzey” and I babysit them every chance I can get. In my spare time I enjoy volunteering with local civic organizations and watching sports.
