Working with the Grisak Group was so easy and fast. We had to get our house sold to be able to buy our next house, and everything got done and fell in place thanks to all the team members here. We would use The Grisak Group for any future purchases!!

I recently purchased my first ever piece of property. The Grisak Group helped me purchase the ranch of my dreams, in Commerce Texas. A bidding war occurred and Sunny Sutton, my agent, helped me secure the property. Working with The Grisak Group was amazing, they made this complicated process so easy! They were so nice, helpful, and professional. I will definitely use them again and I highly recommend!

Sunni Sutton was delightful to work with. She sold the house before it was even listed on the MLS. I give her and the Grisak Group my highest recommendation!

What a great company. They worked very hard to make the sale go so smooth. Even the title company was great and through. Thank you!!

Our home had been on the market for 9 months with another Realty Company. After meeting the Grisak group, we immediately agreed to let them take over. They sold our house within 2 months! Incredible marketing and personal attention! Sunni Sutton, was a breath of fresh air! Her commitment to selling our house was at once immediate and thorough. She listened to our concerns, kept us informed and calm during a tumultuous and emotional transition. We are forever grateful to her and the exceptional team of professionals in the Grisak group. Highly recommend the Grisak Group! Ask for Sunni Sutton!!!


Hi Tom, Sunni and Kathy are working their butts off in my house! I am so excited, it is looking completely different and so cool!!! I love everything they are doing. They both are so creative and innovative. Using some of my things. I just had to tell you how utterly astounded I am - it's gonna be great. Thank you so much for having such a great team.
