Our Team

Jonathan Ogren, Principal & Environmental Planner

Jonathan founded Siglo Group in 2006 to help clients integrate natural systems into land planning and design. He specializes in environmental assessment, regional analysis, conservation planning, mapping, and land use feasibility studies. He is a graduate of the University of Texas at Austin with an M.A. in Geography and the Environment and a B.A. in Biology. He is now on the faculty at the University of Texas School of Architecture, where he teaches graduate students to integrate geographic analysis into their research. One of his first professional jobs was with NASA. The experience changed his direction through the realization of how valuable and irreplaceable natural systems are here on this planet. Jonathan also worked at the Lady Bird Johnson Wildflower Center and Sequoia National Park and has served on the Imagine Austin Comprehensive Plan Advisory Task Force. Outside of work, Jonathan can be found running around Lady Bird Lake or hiking the Hill Country with his sons.

Haley Wagoner, Associate

Haley joined Siglo Group in 2018 shortly after receiving her Master of Landscape Architecture from the University of Texas at Austin. Her background includes a B.S. in Regional Development with minors in Geographic Information Systems (GIS) and Spanish from the University of Arizona as well as a Certificate in GIS from Portland State University. Before moving to Austin for graduate school, she worked in Portland, Oregon where she was involved in restoration efforts for the endangered juvenile salmonid population passing through the Lower Columbia River Watershed. Her academic and professional experience includes GIS analysis, cartography, environmental design, planning, land survey, on the ground restoration, community engagement and environmental education. Haley loves to spend time outside getting her Vitamin D fix whether she is biking, hiking, running, skiing, or most importantly, floating a beautiful Hill Country River.

Clare Coakley, Associate

Clare joined Siglo Group in 2014, when she returned home to Austin after 9 years in Vermont. She received a B.A. in Environmental Studies and Conservation Biology from Middlebury College and an M.S. in Natural Resources from the University of Vermont. Clare’s academic and professional experience includes ecological assessment, invasive plant inventory and management, geographic analysis, cartography, teaching, and communication and outreach. Beyond work, she spends as much time outside as possible, whether volunteering as a Capital Area Master Naturalist, trail running, camping, or hiking with her dogs and family.

Jade Florence, PhD, Associate

Jade joined Siglo Group in 2019, following 9 years of professional experience in sustainable land use, which included ecological planning, landscape design, and sustainable agriculture. Jade’s academic achievements include a Bachelor of Science degree in Bioenvironmental Science in 2010, completion of a PhD in Botany & Plant Pathology in 2016, and winning a Fulbright US Student Program scholarship in 2016. Jade’s skills include technical writing, ecological surveying, statistical analysis, field data collection, and landscape design. In her free time, Jade enjoys long afternoons outdoors and can often be found running, paddleboarding Lady Bird Lake, hiking, camping, picnicking, or painting.

Dave Pietruszynski, Associate

Dave joined Siglo in 2019 after graduating from the Duke University’s Nicholas School with a Master of Environmental Management degree. Prior to 2016 he was a high-tech entrepreneur in communication and consumer electronics, founding and growing companies. He transitioned to environmental sustainability and land use by initially working along the Texas Coastal Bend bays and estuaries focused on restoration, coastal sustainability, carbon markets for coastal wetlands, and education. In his academic work, he concentrated on GIS-based analysis of the ecosystem services value provided by restored oyster reefs in Texas. Dave’s love of the outdoors—hiking, cycling, fishing, hunting, and sailing, drives a passion for finding ways that technology can support good stewardship and help us sustain the earth for future generations.

Karina Gonzalez, Intern

Karina joined Siglo Group in 2018 while acquiring a B.A. in Sustainability Studies, Natural Resource Management from the University of Texas at Austin. Concerned with the intersection of natural resources and the built world, Karina’s academic experience includes studies in ecology, hydrology, physical and human geography, GIS analysis, cartography, energy based policy, and sustainable development. She has professional experience as a laboratory assistant analyzing soil particle size texture and distribution as a means to identify patterns in geomorphic response to extreme weather events in the Carribean. Her personal interests center on the spatial analysis of physical geography, climate change, and development through spatial statistical methods and pattern recognition. Karina likes to spend her free time looking at memes about philosophy and the economy, consuming sci-fi media, and learning obscure trivia.

Kaitlin Tasker, Associate

Kaitlin is a researcher, educator, and designer with 9 years of experience in the environmental science, conservation, and community engagement fields. She specializes in conservation prioritization, decision tools, community conservation planning, land use impact analysis, and cartography. She is a graduate of the University of Texas at Austin with a Master’s degree in Geography, and holds a Bachelor of Science in Environmental Biology from Tulane University. Kaitlin has acted as the primary researcher on multiple projects examining human impacts on the environment and cooperative conservation design. She has also made maps, dashboards and infographics for clients in various industries, camped in remote sections of the Peruvian Amazon, and lived on a boat. Outside of work, she spends her time enjoying the incredible natural places that Sigo Group works to protect and eating all spicy foods.

Ben Labay, Associate
