Working towards the balance between science and art in her design, Allie takes into consideration the aesthetic, social, and ecological impact of any work done in a living, breathing environment. From working in the field and in nurseries she has learned the importance of mathematics and science in responsible design. Whether it’s understanding the relationship of different plant species, calculating the angle of a hill, or figuring out the required length of a winding path, she believes these technical details are essential in creating plans that are functional, seamless, and gracefully beautiful.

Allie is a 2020 graduate if the University of Massachusetts-Amherst with a Bachelor’s degree in Landscape Architecture.

Max is a 2023 graduate of Penn State University, where he received a Bachelor’s degree in Landscape Architecture. During his time there he gained an appreciation for the effects that good design practices can have on a community. Studying abroad provided him with the opportunity to travel to many European cities, including Barcelona, Copenhagen, Amsterdam, and Berlin. After exploring the strong presence landscape architecture has at the roots of these historic cities, he knew he wanted to incorporate these lessons in his career. Max joined Horn & Co. in August 2023, where his keen interest in ecological design is shared by every member of the firm.

Shira uses her passion for sustainability to guide her vision in creating unique spaces that function as their own micro-ecosystems. Photography principles guide her designs, taking special interest in primary colors, symmetry, and balance—all elements she strives for in her photos. She harnesses these skills to create plans that feel warm and lived-in. With a love of travel, Shira also draws inspiration from the green, walkable cities and impressive garden traditions of Europe, and she enjoys bringing a touch of old-world elegance and charm to balance the modern vibrancy of the DMV area.

During college, Shira spent several years working and volunteering on organic farms and foraging produce for food-insecure populations. She earned her Bachelor’s degree in Landscape Architecture from the University of Georgia in 2024.
