Originally from Green Bay, Sarah  was successful in her previous positions as Director of Sales for high end dining cruise companies both in Los Angeles and Chicago.  She has since moved around the country almost a dozen times with her husband’s job, but she's happy to be "home for good!" This experience has helped her gain knowledge of buying and selling homes first hand from a client’s perspective.  Sarah grew up in De Pere, WI, went to St. Joseph Academy and graduated from the University of St. Thomas with a B.A. in Speech Communications.   She loves being back in her hometown, is a huge Packer fan, and is excited about her career in Real Estate and to be working with The David Kaster Team at Coldwell Banker The Real Estate Group.  Sarah lives on the west side of Green Bay with her husband Tom and their two children.









There are many qualities and skills that go into being an excellent real estate professional - integrity, in-depth community and market knowledge, marketing savvy, effective negotiation skills and a high-quality professional network, all of which are hallmarks of how I work.

That said, in my experience as a Green Bay area real estate professional, I've also found that providing the very best service is essentially about putting my clients first. This means keeping myself accessible, being a good listener as well as a good communicator, and responding quickly to your needs.

This "client first" philosophy has always been my approach and it requires me to continually improve my skills and ways of doing business. In addition, I've found that the latest technologies are enabling me to do everything I've always done, only much more quickly and efficiently. They've also helped me to extend the range of services I provide to my clients.
