Holly Griewahn Named 2026 Lenawee County REALTOR® of the Year 

What an honor to be named the 2026 Lenawee County Realtor of the Year! I’m so thankful to be part of a community that has given me so much, both personally and professionally. I wouldn’t be where I am today without the clients who trust me, the colleagues I’m fortunate to work alongside, and the relationships that make this career so rewarding. Thank you for being part of it!
