Eco Logic Staff


Spencer Goehl, Principal
Executive Director

“I grew up in the hills of Brown County and from an early age spent every waking moment outside, exploring nature.  This led me on a path to become an ISA Certified Arborist and I truly loved working with trees, but soon became dismayed at the unsustainable practices of the “Green Industry” including a lack of native plant diversity in our landscapes.  I really wanted to have a bigger and more positive impact on our landscapes and I found that through ecological restoration.”

Spencer started Eco Logic in 1999 with the dream of restoring ecosystems throughout Indiana with a focus on high quality remnant natural areas.  Since that time Spencer has guided Eco Logic through a transformation from a small restoration firm with one crew run by the owners, into one of the premier ecological restoration firms in the Midwest.

In the early years Spencer was involved with each aspect of every restoration project including completing the work in the field and follow up monitoring. Some of his early projects were restoring fire adapted, globally rare ecosystems in northwest Indiana such as Dune & Swale, Oak Barrens and remnant Prairie through projects for the Indiana Division of Nature Preserves. This gave him a unique understanding of the importance and challenge of restoring our high quality remnant natural areas.

Since that time Spencer has overseen many large multi-year government invasive species control contracts on thousands of acres of public land. He has also been involved in the green infrastructure movement and has assisted many municipalities with planning, implementation and management of stormwater BMP’s.

He has focused Eco Logic’s resources on safety, training and employee retention and has built an extremely passionate and talented team of restoration ecologists.

Kevin Tungesvick
Senior Ecologist

“Love of nature has been the core of my existence throughout my life. I grew up on a wooded property in central Indiana where I learned to identify most of the tree species by the first grade. Throughout my childhood and adolescence, my passions would vary between birds, wildflowers, weather, trees, and mammals. My interest in weather led me to earn a Bachelor of Science degree in Atmospheric Science from Purdue University. Understanding the effects of climate change on plant communities has become one of my passions.”

Kevin worked as a meteorologist with the National Weather Service for three years following college, but soon his love of plants called him back to the nursery industry where he developed the product line and managed sales and production at a wholesale native plant nursery for 22 years. During this tenure, Kevin was involved in numerous large scale restorations throughout Indiana as a material supplier and technical advisor. Some of the ecologically significant wetland and prairie restorations in the Midwest have benefited from Kevin’s expertise.

While working at the nursery, Kevin also honed his botany skills by performing floral inventories for park districts and private individuals. His floral inventory of Mounds State Park was published in the Proceedings of the Indiana Academy of Science. In addition, Kevin has authored numerous articles published in nursery trade publications and nonprofit newsletters.

Kevin’s love of nature has fostered a strong environmental ethic which is reflected in all of his work.  The experience and pragmatism gained through two decades of work in ecological restoration allows Kevin to develop scientifically sound and workable solutions for our clients.  Kevin looks forward to developing successful solutions for green infrastructure, native landscaping, plant community establishment, invasive plant management, and master planning for large properties.

Matt Fox
Project Manager

“My family’s love for the outdoors was passed on to me, although belatedly. As a young man raised on a small family farm, I would long for the city sidewalks and fast paced urban lifestyle, while tilling the field and feeding the animals. The glamour of city life didn’t last long however, and at age 24 I made my first attempt at the Appalachian Trail. Though I didn’t last for more than a few weeks, I regrouped and came back the next year and completed hiking a large portion of the trail within two months. When I returned I knew then that I wanted to dedicate my life to protecting nature both in its magnificence and minutia. This experience cemented a lifelong communion with nature and kick-started my career in Ecological Restoration.”

Matt Fox has acquired almost 15 years of experience working in the field of ecological restoration.  His career began as a crew leader with AmeriCorps working in cooperation with The Santa Clara Open Space Authority in California monitoring and managing various invasive species.  Matt then served as the Ecologist’s Assistant for California State Parks both in the Northern half of Big Sur and then Monterey Bay.  There he was responsible for such tasks as seed collection/propagation/planting, flora and fauna monitoring, and a implementing a variety of IPM (integrated pest management) techniques, both mechanized and manual.  In 2006, Matt and his wife moved to Louisville, Kentucky where he worked on the woodlands restoration crew for Olmsted Parks Conservancy as a Biological Technician. Here he was responsible for trail maintenance, vegetation surveys, and IPM.  While at Eco Logic, Matt has served as project manager for several long term projects including a restoration project at the TNC  Prairie Borders Complex, and several invasive species management projects at Hoosier National Forest. He also oversees the DNR Kudzu eradication contract for the DNR/State of Indiana and recently completed a large scale Ailanthus reduction on the 600 acre Sherman/Minton Nature Preserve in Floyd County.

Natalie Marinova
Nursery Manager/ Field Botanist

“I have always enjoyed gardening in general since I was a young child following my mom around the yard.  My interest in native plants and sustainable practices culminated in college and continued to grow from there.  My work with Eco Logic over the past six years has also allowed me to deepen my understanding of the bigger picture of ecology beyond our backyards.  Now a new mom myself, I am excited to share the wonders of the outdoor world and of native plants with our daughter!  Through hiking, skiing, camping and of course, digging in the dirt, I hope to instill in her and those around me, the need for continued preservation of our natural lands and the native flora and fauna dependent on those lands.”

Natalie has a B.S. in Agriculture from Berea College.  She had been working with native plants for over twenty years.  From her introductory years as a student worker on the grounds crew at Berea College to her current position of Field Botanist and Nursery Manager at Eco Logic, Natalie has worked in the native plant landscaping and nursery field across four states – Kentucky, Ohio, North Carolina and Indiana.  This regional experience has exposed her to a wide range of plants.  She joined the Eco Logic team in Spring of 2010.  She oversees many of the installation projects, leads crews in invasive plant treatments, is a consultant on plant inventory projects, and implements the companies’ botany training.

Sam Shoaf
Restoration Supervisor

“I grew up hunting, fishing, camping, and hiking the woods of Indiana, developing a love for nature and a desire to learn the ecology of our landscape. While studying Wildlife Management at Purdue I learned about the threat of invasive species and their detrimental effects on native ecosystems, and was introduced to some restoration techniques through my course work.  During his studies I took many courses on plant identification, habitat management, forest ecology, wildlife investigational techniques, and fire ecology. “

After graduation in 2014 Sam worked at Eco Logic as a Seasonal Restoration Technician, gaining valuable experience with a variety of restoration techniques in many different ecosystems.  He adapted quickly to the challenges of fieldwork, and spent much of the winter of 2014-2015 participating in the restoration of the Oak Savanna at TNC Prairie Borders Complex.  During this project he logged many hours of forestry mower and chainsaw operation.   In 2016 Sam became a Restoration Supervisor for Eco Logic and has been a valuable asset to our team.

Caleb McCann
Restoration Supervisor

“Biology has always been my passion. As a child I would spend hours in the woods next to my home studying plants and wildlife. This continued in college, where I studied Biology with an emphasis in ecology. Conversely, upon graduating college I worked for a pharmaceutical company, in an aseptic environment, making medicine. This experience, though valuable, reinforced my love for the outdoors and my desire to work for the betterment of the natural world. After two years in that position I made the jump to Eco Logic and have loved every moment.”

Caleb graduated Cum Laude from Indiana Wesleyan University with a major in Biology. As part of his course work he studied at Au Sable Institute of Environmental Studies where he gained hands-on experience with wildlife and restoration ecology. Since starting at Eco Logic in 2014, Caleb has earned his Commercial Drivers License, Indiana Pesticide Applicators certification, and Category 3a Ornamental Pest Management certification. He has become proficient in operating a skid steer with multiple attachments, including a Fecon forestry mulcher, as well as the use of herbicides in responsible restoration strategies. He was utilized extensively as part of the effort to fight the Callery pear infestation at Crane Naval Base and in restoring 170 acres of black oak savanna in Northern Indiana. Caleb’s passion for restoring native plant communities and diligent work ethic make him a valued member of the Eco Logic team.

Brant Anderson
Restoration Supervisor

“I grew up in southern Indiana near the town of Madison. My summers were spent playing in creeks, hiking through the hollows of the Ohio River Valley and camping along the now decommissioned Indianapolis Railroad. From an early age I longed for adventure in the outdoors, so after graduation I followed my passions, packed my bags, and moved to a small town in eastern Tennessee. There I worked as a raft guide, leading droves of people on hundreds of trips down the Pigeon River. At the end of my adventures in Tennessee, I found myself back in Indiana, and shortly thereafter was hired by Eco Logic.”

Brant joined Eco Logic as a Restoration Technician in the fall of 2014. In his first year he took part in two large scale tree plantings along the Ohio River, as well as a stream restoration along Sugar Creek in Bartholomew County. Because of his diligence, attention to detail and creative spirit, Brant was asked back the following spring to continue on as Restoration Technician. He quickly picked up on safe herbicide application practices and honed his plant identification skills. Over the following 2 years, Brant worked on many high impact projects such as the black oak savannah restoration at Prairie Border for The Nature Conservancy, Ailanthus reduction at Sherman Minton Nature Preserve for the IDNR, and reed canary grass control at Otter Creek for Hoosier National Forest. In 2017 Brant was promoted to Restoration Supervisor and holds a Forest Pest Management license in both Indiana and Kentucky. He has expanded his work skills including proficiency with chainsaw and heavy equipment operation. Beginning in 2017 he became the field lead in working with IDNR in the eradication of Kudzu in nearly 36 counties in Indiana, and continues to be a valuable asset to the team.

Katherine Zaiger
Green Infrastructure Supervisor

“The seeds for my passion for nature were three pine trees at the end of an apartment complex cul-de-sac in Indianapolis and a copy of Thoreau’s Walden. Growing up on the east side of Indianapolis, my opportunities to experience nature were few and far between. For that reason, the natural world has been, and continues to be, an ever-unfolding mystery with which I will forever be enraptured and will always find the greatest fulfillment. I am very grateful that my work at Eco Logic enables me to infuse nature back into urban areas and share my greatest joy with the city that raised me.”

Katherine has a M.S. in Rangeland Ecology from Oklahoma State University and a B.S. in Biology from Indiana University. She came to Eco Logic in the spring of 2016 with over five years of work experience with native ecosystems between her graduate work and her time as a Senior Research Technician for an ecology laboratory at Indiana University. Her education and work has primarily focused on native prairie restoration techniques and native plant community dynamics. She has surveyed many prairies across the Midwest and has been a lead on the installation of several prairie restorations in Oklahoma, Kansas, Illinois, and Indiana. In the fall of 2017, Katherine became the Green Infrastructure Supervisor at Eco Logic and currently oversees the installation of rain gardens and native landscapes in Indianapolis, Bloomington, and beyond.
