Thaumas P. Ehr, RLA
Mr. Ehr has been practicing Landscape Architecture in the Southwest United States since 1980. He was raised in rural Southeastern Wisconsin and first visited the Southwest with his family in the early 1960’s. He attended the University of New Mexico and graduated with a degree in Biology and Chemistry anticipating a career in veterinary medicine in 1974. He entered the graduate school of Geology at the University of Oregon in 1977 and ultimately received a graduate degree in Landscape Architecture in 1980.

During his career he has worked in a number of environments in the Southwest: first in mountain resorts in Vail, Colorado and Snowbird, Utah, then the High Deserts around Moab, Utah, Santa Fe, New Mexico and West Texas and finally in the Mojave Desert in Clark County Nevada and Southern California. For the last few years, he worked as a consultant designing vineyard estates and wineries in Napa and Sonoma Counties in Northern California.

After living in these places in the Western States; the Sonoran Desert and his life long commitment to Arizona have made him refocus on this place where work and lifestyle are seamless.

Throughout his career he has worked to enhance the quality of life in this region by developing design solutions that respect connections to landscape, history, peoples and values which are distinctive to the region and to solve the problems that come with growth and new settlement patterns limited by water use.

Tom’s practice in the region is a commitment to making an already spectacular place remain that way and to build upon its natural evolution to become one of the most unusual parts of the world.

Shero Holland
Originally from Alabama, Shero is a biologist and environmental planner who grew up in Plano, Texas, but came to Arizona State University for graduate school in 1994 and has been in Tempe ever since. Shero has a bachelor's degree in geology from Rice University and a master's degree in biology. For every project, he especially enjoys field work, technical writing, and research. As an avid bird watcher, he is involved in a long-term research project with Arizona State University, which involves the identification of over 100 species of birds at over 50 sites across the Valley.

Prior to joining Del Sol Group, Shero worked in the local environmental-consulting industry for 7.5 years before taking a year off, which included efforts to remodel his 1950s home with environmentally friendly features, such as solar panels, energy-efficient windows, a tankless water heater, a ridgeline-vented roof, desert landscaping, compost bins, and an urban orchard/garden. Shero adds valuable expertise to the Del Sol Group team with his unique skills as a biologist/environmental planner and excellent technical-writing skills.

Christy Confar R.G., R.E.A
Christy grew up in Tempe, Arizona where she attended High School in Tempe and went on to graduate from the University of Arizona in 1996. At the UofA, she met Noelle in the Geosciences program where they became friends and studied the geology of Southeastern Arizona. Christy moved on to graduate school in Portland, Oregon and received her M.S. in Geology. Her Master's thesis focused on high temperature geochemical modeling along the Cascades-Basin and Range transition zone. Her thesis also included publication of a 7.5-minute quadrangle geologic map, which was funded through both the State of Oregon and the U.S. Geological Survey. Following completion of her M.S. degree, Christy taught geology and earth science courses at Portland community college before re-entering the environmental consulting industry.

Beginning in the mid-1990s, Christy has worked for large-scale environmental consulting firms helping her team solving hazardous material issues, providing mitigation solutions, and providing field surveys of dangerous chemicals and hazardous materials. Christy is also an accomplished project manager with well-developed skills that keep her projects on time and on budget. In late 2009, she realized her career needed a change of pace and with two kids entering grade school, she decided to join her long-time friend Noelle to see what it's like to work for a small business. Her background, technical expertise, and charisma are an excellent fit into the Del Sol Group team.
