I’m originally from Northeast Ohio where I was an Ohio Certified Volunteer Naturalist (OCVN) and lead nature programs at Holden Arboretum in Kirtland, Ohio. I’ve always loved the outdoors, camping and hiking and would explore the thick woods of Ohio often. I moved to Colorado to experience the mountains and the culture of an active lifestyle. I most enjoy sharing my love for nature with others, particularly children and young adults.

Whether it's for work or play, being outdoors brings me joy! As a Volunteer Naturalist, I love to explore and learn with others about the natural world around us and to help people of all ages find their own connection to the land.

My interest in the outdoors can be attributed to camping in the mountains as a child as well as growing up in a city with a strong nature focus – Boulder! I love going on bird walks, learning about plants and their properties, and exploring our state’s natural beauty. I particularly enjoy watching chickadees in my backyard and finding limber pines in the Rockies.

I am a mostly-retired lawyer and an outdoor adventurer, with many years of experience as a backpacker, hiker, rock climber, and outdoor guide/educator. I am excited to be part of Boulder County's volunteer naturalist program, to learn more about this area's natural history and then share with my community what I've learned and what I love about the outdoors.

I retired from Boulder County Parks & Open Space in 2022. I love sharing information about the natural world and our local history with children and adults. I also love teaching astronomy and helping people better understand how celestial motion works, and how dark skies are important to us all.

I have been an Open Space volunteer since 2002. I studied Biology at CU Boulder and have always been drawn to the great outdoors and all that it offers. I enjoy being on the trails any day of the year. Also, I have been a raptor monitor with City Open Space since 2004.

We moved here 9 years ago from North Carolina. I've always enjoyed hiking and other outdoor activities. I'm now also interested in green/sustainable home construction. I've thoroughly enjoyed my time as a volunteer.

I grew up in northwestern Ohio. My favorite place was always outside. I have an undergraduate degree in Biology. Living in Colorado has been a great gift, and I need to give back to the community in appreciation for all I have received and experienced. Becoming a volunteer naturalist is the perfect way to meet that need. It combines my curiosity about the natural world, my love for the outdoors, and the opportunity to provide service to those who also call Boulder County home.
