Meet Sonja Mize.
Owner, partner, and the creative force behind every project we build — a third-generation builder with an artist's eye and 30+ years on the job.
"Dreams only come true when you believe in yourself, take chances, and Trust God."
-- Sonja Mize, Owner & Partner
I am the 3rd generation on my father's side of general contractors. I learned so much about home building at a young age that it only made sense to study the trade. My mother was an award-winning artist. Creativity came naturally for me. I fell in love with the interior design as well as the construction side of the field.
I was raised in Lubbock, Texas and studied at Texas Tech. It has been a rewarding 30+ years in this career, being blessed with the ability to win many awards in various areas including parade homes.
Now based in Dallas Fort Worth, I continue to serve communities across the metroplex. Female builders are still somewhat rare in this industry. Through determination and the support of my family, I have been successful and blessed to build beautiful luxury custom homes for some amazing people across this beautiful region.
