Harvest Rain

Our Team of Rainwater Professionals

Our team is small but mighty. Each of us helps people achieve their goal of harvesting rain, whether that’s answering front-end questions or finessing a final system design to align with your budget and property needs.

From the front office to construction to service, our team embraces the benefits of rainwater. Who you won’t see pictured here is our crew – they’re too busy out on site! – but they are at the very heart of what we do.

Harvest Rain proudly calls Texas home and we have an intimate knowledge of the best way to approach, design, and install systems all across the state.

Meet our team below and don’t be shy! Give us a shout, we love providing people with the knowledge they need to make their most informed decision.

President, Owner

James Grizzard

James Grizzard was born in Austin and raised in San Antonio. James has over 15 years of experience installing and designing water conservation systems and has received state and national awards for rainwater system design. 

Working closely with builders, architects, and developers, James specializes in commercial, municipal, and community projects.

James is also an avid San Antonio Spurs fan and hopes to one day challenge Manu Ginobili to 1V1.

Josh Tavarez


Josh Tavarez was born and raised in San Antonio, Texas. He attended Texas A&M University, and soon after joined Harvest Rain in 2015, as a member of the install crew.

After accumulating years of hands-on rainwater system install experience, Josh went on to become our Construction Manager successfully leading hundreds of installations. Now as Director of Operations, Josh oversees the big picture as well as our Generators division. 

In his spare time, Josh enjoys spending time with friends and family, mountain biking, hunting, and running with his dog.

“I appreciate how reliable a generator can be in a case of emergency and they are the perfect partner to a rainwater system. With power outages due to weather events, or our electrical grid being taxed by volume of people/usage, generators provide life-saving relief.”- Josh

Adam Brown is a native Texan, born and raised in the piney woods of Tyler, Texas. Adam joined Harvest Rain with a background in management, sales, marketing, and live music event planning with a passion for supporting local communities and sustainable alternatives for the future.

Adam studied at Colorado State University and graduated with a Bachelor’s degree in Business Finance. After living in Fort Collins, CO from 2001-2017, he moved back to his home state of Texas to get back to his roots and raise a family in the Hill Country. In his spare time, he enjoys playing guitar, gardening, hiking, swimming holes, and brisket tacos.

“I enjoy meeting new people and helping them design high-quality rainwater harvesting systems to meet their needs for both residential and commercial properties. With our intense climate and rapidly growing population, we offer a reliable and environmentally conscious alternative while conserving and protecting our natural resources. That’s a win-win in my book.”

If you choose Harvest Rain for a rainwater installation, you’ll have the pleasure of meeting our Construction Manager, Michael Clark. 

Originally from Huntsville, TX, Michael attended Texas State in 2015 and dove into the rainwater industry immediately after graduation. His career with Harvest Rain began as a member of our installation crew and through dedication and an eye to both detail and exceptional customer service, Michael is now our Construction Manager.

Aside from work, Michael loves spending time with family and friends and you can often find him outside shooting hoops – ask him about his ultimate frisbee team! 

I enjoy installing a more sustainable approach for overall community water usage, one rain collection system at a time. I feel privileged to be a part of Harvest Rain, and I love seeing the happy faces of customers after designing and installing systems built specifically for their needs.” -Michael

If you give us a ring, you’ll most likely speak with Mandi, our front office superstar!

Although I have spent the last few years succumbing to my “travel bug” as a former resident of Idaho and Ireland, I decided to come home. I’m a sixth-generation resident of Johnson City so our roots run deep in the land and Judy Garland said, “there’s no place like home.”

As the newest member of the Harvest Rain team, I face new and exciting aspects of the job every day! I enjoy speaking with people about their individual situations and how to incorporate rainwater collection into their daily lives; whether the goal is to have a safe and self-reliant water source in their home, or to provide chemical-free water to their livestock, rainwater provides an empowering alternative water source to sustain life in an ever-changing Texas landscape. When I’m not at the office, I’ll most likely be cheering on my daughter at an extracurricular activity for Johnson City Middle School or 4-H show. Ask me about our goats!
