Alex Wenthe, Owner/Ecologist. I started at Quercus as a technician after graduating from UW-Madison with a degree in Biological Aspects of Conservation. Working with Jim, I gained valuable on-the-job training and found my passion for ecological restoration. After a few years, I made the very tough decision to leave Quercus to work for the WDNR State Natural Areas Program. Alongside a team of passionate biologists, I helped preserve and restore some of the highest-quality natural communities in the state. A few years later I was tasked with coordinating a new program within the WDNR, coined the “Landowner Lottery”. In this role, I traveled the state to provide ecological restoration and rare species management advice to private landowners. Inspired by all the dedicated colleagues and landowners I had met, I returned to UW-Madison to complete a master’s degree in Ecological Restoration with the Department of Botany. In 2018, I returned to Quercus as an Ecologist and felt like I never left (except for trying to find tools in the new shop). Being fortunate to practice ecological restoration in many different settings, public, private, and academic, it is clear to me that Quercus is a unique company. I am proud to be a part of it.

Ecological restoration has transcended into my personal life as well. It has taught me that we all live together on a beautiful planet, full of unbelievable things, and we are more connected to these things than we may ever know. So when I’m not working, I enjoy traveling to new places and experiencing what the world has to offer with my lovely wife Tori and sons Oliver and Maxwell.

Jim Elleson, Founder, Senior Vice President.  I got my start in restoration at the feet of my grandfather, who worked out of the Wisconsin Conservation Department’s Forest Protection Headquarters in Tomahawk, and my uncles who farmed in western Wisconsin’s Coulee region. I took a detour for a 20-year career as a mechanical engineer, helping people use less energy in homes, offices, and factories. Working on my own land in the town of Vermont led me to a deeper understanding of what it means to take care of the land, and I started taking classes and educating myself to broaden my ecological knowledge. I started Quercus Land Stewardship Services in 2003, and since then we’ve been steadily increasing our land management capabilities.

I love seeing the impact that we have on our customers’ properties, and I’m proud of our dedicated, professional crew who make it happen. Since I recently stepped down from the owner and chief executive roles, I’m looking forward to more opportunities to get out on the river or primitive camping with my grandkids.

Brittany Pierpont, Vice President. I received my Bachelor’s in Environmental Science with an emphasis in Conservation and Resource Management from Carroll University. I have been with Quercus since 2012 and have advanced training in Wildland Fire management. I enjoy restoring Wisconsin’s native ecosystems and seeing the transformation each site goes through as well as communicating with landowners to discuss their goals and the potential their land has. One of my favorite things is discovering hidden gems like uncommon plants, birds, and incredible rock outcroppings. When I am not working, you can find me on the landscape enjoying the Driftless area dreaming about the potential of restoration everywhere I go. My favorite activity is trail riding and horse camping with my trusty steed, Smokey.

Jaya Elleson, CFO and Crew Leader.  I have been with Quercus since 2004. I am a certified Emergency Medical Technician and first aid trainer, and have a Bachelor’s in Biology and Environmental Studies and have extensive training in Wildland Fire management.

Jake Michaels, Senior Project Manager.  I joined the Quercus crew in 2013. I graduated from Carroll University where I received a Bachelor’s degree in Biology. Working with Quercus has afforded me some invaluable experiences and advanced training in Wildland Fire management. I’m grateful to be employed in a field that allows me to direct my passion for Nature into a productive purpose. When I’m not working I spend time outside enjoying the fruits of our daily labor at a slower pace. I also enjoy a variety of water and snow sports, and I’m especially fond of wind-driven activities.

Bill Ishmael, Prescribed Burn Specialist.  I joined Quercus in 2016 following my retirement from the WI-DNR where I worked for 30 years as a Wildlife Biologist, primarily in SW Wisconsin. I received a Bachelor of Science in Wildlife Ecology (1979) and Master of Science in Wildlife Ecology (1984) from UW-Madison and am a Certified Wildlife Biologist with The Wildlife Society. I have extensive experience in wildlife population ecology, wildlife damage abatement, public lands management, invasive species control, and habitat restoration. I enjoy working in the outdoors with people who share the common goal of restoring and enhancing native vegetation communities that support a diversity of wildlife. When not working with Quercus, you can find me fishing or kayaking (or both) on the waters of southern Wisconsin.

Originally from southeastern Michigan I have worked throughout the Great Lakes and upper Midwest region including Michigan, Ohio, Minnesota, North Dakota, and Wisconsin. This work allows me to apply my interests in botany and the art of sawyery at a professional level. I have always had a love of nature and the outdoors and often spend my free time hiking, canoeing, and botanizing along the Wisconsin River and throughout the Baraboo Range. When not working or otherwise spending time in nature I enjoy cooking a nice meal, local stout, a good book, and catching up on my sleep.

In my free time, I can usually be found exploring various natural and cultural attractions in the Madison area, fishing, reading, or playing board games.


Kevin Mason, Project Manager.  I joined the Quercus crew in the summer of 2018. My childhood summers often involved trips to national parks and I gained an affinity for the outdoors early in life. I graduated from Lawrence University with a degree in Environmental Studies. I spend much of my time outdoors, hiking and backpacking as much as possible. When I’m not outside I enjoy playing music and sharing good food with good people. It’s a pleasure to spend my days working with this team.

Eliot Gore, Ecological Landscape Manager. I grew up on a colonial replica estate created by my father who owns a landscaping company just north of Milwaukee. For most of my life, I have been involved in the creation of formal gardens in the North Shore of Milwaukee County. I went to school to obtain a Bachelor’s Degree at The University of Wisconsin in landscape architecture with a focus on ecological restoration. I have always been an admirer of Wisconsin’s natural spaces, combined with my background of plant affinity and the resources and legacies at UW, I found myself passionately seeking out ecological restoration related classes. After reading authors such as Leopold and Muir, I devoted my life to understanding Wisconsin ecology and finding ways to apply such values as they put forth. After graduating I began working with Quercus as an ecological restoration specialist. Combining ecology and landscaping had come to evolve as a natural life goal, bridging everyday life with the natural beauty Wisconsin has to offer. My extensive experience as a landscape designer and implementer, along with my formal education and experience as an ecological restoration specialist allow me to design landscapes that best serve people and the land. My other passions include dance, kendama, Native American flute, and writing poetry.

I started working with Quercus in the spring of 2020 after 2 years of seasonal wildlife technician work in Utah, Oregon, and Texas and 2 years with the Wisconsin DNR wildlife department. I have a B.S. in Wildlife Ecology from UW-Madison. I joined Quercus to immerse myself in restoration and begin work on the land I grew up on in Beaver Dam, WI. Though I said I would never return, there is something that ties me to that land. I’d like to think if my grandpa had known, the woods would be in a different condition than it is today. Education is important to conservation and an area I see myself getting more involved in. I am proud to work for a company that encourages education of its customers and staff. I also enjoy working where I can let my hair get out of control, it means I’m working hard.

Karlee Ketelboeter, Crew Leader. I joined Quercus in early 2021. I graduated from the University of Wisconsin – Platteville in December of 2019 with a degree in Reclamation, Environment and Conservation. After a seasonal position out in Montana doing wildland restoration work, I made my way back home to Wisconsin. I feel very lucky to be able to work outside in the beautiful natural places this state has to offer! When I’m not working I’m usually spending time with friends and family, hunting, hiking, or enjoying various other outdoor activities.

Kaley Lee, Office/HR Manager, Restoration Specialist. I started at Quercus in February 2021.

Befores Quercus I worked in the plasmapheresis therapeutic and diagnostic industry within a plasma center for 7 years, where I held multiple management positions. While working within a plasma center, I found that I had a knack for business management, so I went back to school to earn my Master’s degree in Business Administration from Indiana Wesleyan University in 2017. After earning my degree and some inner growth, I decided to chase my deeper passion for conservation/restoration within our beautiful state of Wisconsin, where I found my place within the Quercus family! In my free time I enjoy hiking, kayaking, fishing, weightlifting, running, oil and acrylic painting, reading, traveling, and a cold beer on a hot summer day! My favorite quote is “Dream as if you’ll live forever, live as if you’ll die today.” – James Dean.
