Having never truly had a hometown, I am dedicated to building a sustainable community in my adoptive hometown.

I have my Bachelor's degree in Asian history from the Air Force Academy and an MPA from Georgia State University. Hiking, gardening, movies, reading and great beer are a few of my favorite things. I love to travel, see new things, meet new people and challenge myself whenever I can. I run, sometimes a long way and sometimes short but fast.

Danielle grew up in the Texas Hill Country, where her love of the outdoors as a child instilled a deep respect for the environment, and a strong desire to preserve our natural surroundings.

When she met her husband, Jesse, they dreamed of setting roots and raising their children in the pristine Texas Hill Country, and of eventually working together as a husband and wife team. Danielle’s vision of preserving the Texas Hill Country, and building beautifully sustainable homes eventually took hold. As their paths narrowed, Danielle and Jesse realized how their passions complemented each other, and all roads pointed to the creation of Younger Homes in Austin, Texas. It was during her studies and research at Texas A&M University, Danielle began to hone her innate desire to be a part of making a real difference in creating a sustainable world for future generations.

She received her Bachelor of Science in Bioenvironmental Science with a Minor in Agronomy, as well as a Master of Public Health with an emphasis in Environmental and Occupational Health. Through national and international research in Public Health and Environmental Toxicology, she began to understand the impact of the environment on human health, and the importance of protecting public health through educating individuals to make informed choices. After graduation, she began a fulfilling and successful career working for a major Oil and Gas company, where she helped others better understand the impacts of Environmental Health and Safety to deliver safe operations offshore. The home is where families spend the most time, energy, and resources, and it is in this place where we can all make a difference. Danielle’s background shaped beliefs that through education and awareness, environmentally sustainable and healthy homes, will become standard building practice. She is confident the vision of Younger Homes will protect the health of individuals, communities, and create a sustainable and healthy world for her children and future generations.
