Andy Rettke
Founder and CEO Sonova Construction
Hi, I’m Andrew Rettke — a former high school teacher and coach turned general contractor, business owner, and proud Plano resident. My journey into construction wasn’t a straight line, but it’s been driven by the same core value that guided me in the classroom: take care of people, and the rest will follow.
For over a decade, I’ve been helping homeowners, businesses, and organizations bring their projects to life — from small repairs to large-scale remodels and new builds. Before that, I spent seven years as a teacher (five in Plano ISD), where I learned the importance of communication, integrity, and building trust — skills that I now bring to every client relationship.
I work with a talented network of subcontractors and a committed team who share my “no shady work” philosophy. We believe in clear communication, fair pricing, and delivering high-quality results that last. Whether we’re painting a school, remodeling a bathroom, or managing a complex insurance restoration, we approach each project with the same level of care as if it were our own home.
When I’m not on a job site or meeting with clients, I’m spending time coaching wrestling, hunting, spending time with my wife, or tackling construction projects around my own home. I’ve called this community home since 2000, and am always looking for ways to give back, whether it’s helping a neighbor, supporting local events, or simply being there for my community.
My Mission: Build trust through craftsmanship, honesty, and service.
Our Promise: We’ll treat your project like it’s ours — no shortcuts, no surprises, just quality you can count on.

The Team Behind Sonova Construction
At Sonova Construction, our people are the foundation of our success. Each member of our team brings unique skills, passion, and dedication to ensure that every project exceeds expectations.
Hi, I am Austin Harrell, and for the past five years I’ve been proud to call DFW home. Construction has been part of my life since college, when I worked with a general contractor while earning my law degree. After school I decided on a change of pace and spent three years as a licensed property insurance adjustor. My background in construction combined with my law expertise, gives me a deep understanding of contracts, claims, and the importance of protecting homeowners’ best interests. Over time, I realized I didn’t want to stay behind a desk in endless meetings. I saw how valuable my skills could be in construction management. Homeowners often need someone they can trust to navigate the process, avoid pitfalls, and make sure their investment is protected. That realization is what led me to co-found Sonova Construction. Today, I get to combine my background in insurance and law with my passion for working directly with people, helping them bring their vision for their home to life. As a project manager and sales professional, I focus on guiding clients through every step of the process, from the first conversation to the finished project. I know how overwhelming construction can feel, especially for first-time homeowners, and I see my role as making that experience clear, smooth, and ultimately exciting. Outside of work, I enjoy watching sports, golfing, and being active in my church community. I also had the privilege of playing college football as a running back for Illinois Wesleyan University, an experience that taught me the importance of teamwork and perseverance, qualities I bring into every project. At Sonova, my goal is simple: to protect clients, earn their trust, and deliver results that turn their dreams into reality.
