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.

Project Manager and Co-Founder
Hi, I’m Ryan Rettke. I’ve been part of the Plano community for 25 years, am a proud alum of Plano East Senior High, and have spent the past 11 years in the construction business. Before co-founding Sonova Construction, I spent time learning from leaders in the industry in both hands on work, and as an experienced project manager. I absolutely love what I do. From roofing to full remodels, I can take care of any project with no stress to you. I specialize in fire, flood, and storm mitigation and restoration. Whether it's helping families recover after a disaster or ensuring a job site is safe and clean, I bring energy, knowledge, and a results driven mindset to every project. As a former college baseball player, discipline, teamwork, and competitive spirit I developed on the field translate directly into my work. I approach construction with that same focus I learned on the field, leading my team, staying on top of details, and always aiming for a home run in execution. When you have me on your project you get the driven energy of a competitive player, as well as someone who knows how to lead a team to victory. When I’m not managing projects and helping customers, you’ll find me spending time with friends or having fun outdoors. I’m all about hitting the golf course when I can! If you ever want to talk projects on the course you can count me in. I also love to play Pokémon Go with my girlfriend. Gotta catch ‘em all!

Project Manager and Co-Founder
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.

Project Manager and Sales Se hablo espanol
My name is Dylan Johnston and I’m proud to say I was born and raised right here in Plano, Texas! I am a graduate of Plano East Sr. High School and Texas A&M University, and an active member of the Murphy Chamber of Commerce. This community has been home my whole life, and that is why I love helping families and homeowners here and around DFW with their construction projects. I know what this area means to myself and others, and I want every project I’m part of to reflect that same sense of pride. Before stepping into construction management, I worked in supply chain, flooring, and roofing. These experiences formed my foundation of understanding business operations such as procurement, manufacturing, distribution, sales, and everything in between. Over the past two years in construction, I’ve jumped in head first learning the ins and outs of roofing and remodeling, and focusing on what really matters. I promise honest communication, fast response times, quality work, and making the process as smooth as possible. One thing that really helps me connect with both clients and crews is being fluent in Spanish. It breaks down barriers, builds stronger relationships, and ensures everyone is on the same page. At the end of the day, construction is about people. Listening to what they need, guiding them through the process, and delivering on promises. That’s the part of the job I love most. Outside of work, you can usually find me at the gym, checking out new restaurants, or traveling whenever I get the chance. I’ve always been active in sports like basketball, soccer, and MMA, and those experiences taught me the value of discipline, teamwork, and keeping a competitive edge. These are traits that I carry over into how I approach my work. For me, sales isn’t just about putting pen to paper. It’s about trust, creating relationships, and delivering a great final product while providing excellent service. That’s what you get when you decide to work with me.
