Meet the Team

Philip Hosmer, Executive Director

Since my earliest memory, I have always been drawn to and nourished by the outdoors. My father instilled in me an appreciation of the simple joys that our world offers us. The sound of leaves underfoot in autumn, the warmth of the sun on a cold winter day, the scent of pine trees in the morning, and the mist from a moving creek against your face on a summer afternoon. These elemental pleasures, scientific research shows, are vital components of our physical and mental health. But society has veered sharply away from being outdoors. The average adult spends 93 percent of their time indoors, where they are looking at a computer or TV screen for 10 hours and checking their phone 80 times. It is my mission to bring the healing, restorative properties of the natural world into the lives of others through Nature Worx. I formed this organization drawing on my experience leading several other not-for-profit organizations focused on family support and outdoor recreation. I am excited by the team of professionals we have assembled, and by the positive impact we are making in peoples’ lives.

Erin Quinley,

Director of Partnerships

When I was 19, I went for a walk in the woods alone at night time, I had forgotten my flashlight and I had to walk a quarter of a mile down a path in the forest to my home. I was terrified.  But I knew myself better when I arrived home that night, I had felt the power of the natural world and the smallness of my "self" and realized that I was its student, not its master or competitor as I was raised to believe.

Since that night, I have shared countless experiences with people of all ages and backgrounds in various natural settings; each one unique, powerful, and humbling. My professional and personal life have afforded me experience with children to adults, at-risk populations, people with special needs, trauma, addiction, affluence, LGBTQ+, the full range of the Autism spectrum. I have worked as a rock climbing and back packing trip leader, camp counselor, special needs counselor, ropes course facilitator, team building facilitator, on duty interventionist, behavioral interventionist, mentor, coach, peer and friend to many.

I believe in Nature Worx’s mission to promote healing through intentional outdoor programs . The end-game is always the same: get people outside and let them see, feel, taste, touch and smell what is real and true. Hopefully this leads to healing, maybe change will come of it, at the very least, like my walk in the woods, it shows them they don't have to be afraid.

I’ve been an outdoor enthusiast all my life. From camping to horseback riding, geocaching and white water rafting, I’ve found participating in nature to be a vital part to staying mentally as well as physically healthy. I especially enjoy going to new places and learning about their unique history and characteristics. I spent several years leading college outdoor adventure trips and am a professional business coach and strategic consultant.

Kate Gerwin, Nature Worx Guide

Nature and I have been friends my whole life, though it is only relatively recently that I have come to think of myself as a "nature person." As my own awakening occurred, I came to see my relationship with nature as just that-- a relationship. Nature accepted me as I was and didn't need me to be a certain way to enjoy her. I came to find that the more time I spent in Nature, the more I became aware of her dynamic and healing powers.

These days, time in Nature sustains me in a way I didn't know was possible. Whether it is out on the Appalachian trail or in the privacy of my own backyard, I lean on Nature as a tool for self-reflection, revitalization, and peace. In my work as a mental health therapist, one of my greatest joys is connecting my clients to the healing power of Nature and watching them build their own relationship with her. It is an honor to be a part of the Nature Worx team and join in the mission of connecting individuals to Nature!

Sage Raindancer, Nature Worx Guide

In the past few decades my jobs have varied greatly from military police to professional athlete to massage therapist; from cycling instructor to massage therapy instructor; and from waitstaff to dog handler. Over the years my passion for service plus my vocation in alternative therapies combined with my love for the outdoors have lead me to the path of becoming a certified nature and forest therapy guide.

Frank Lopez, Nature Worx Guide

Growing up in the forested mountains of western Pennsylvania, we would explore the woods frequently, from picking blackberries to climbing the fire tower for a birds-eye view of thousands of acres of woodland. At 14 my life changed when I entered St. Francis High School, a Franciscan Seminary in Ohio, where I first learned about St. Francis of Assisi and his love for creation. After leaving the seminary, and working as a forester for over three decades, all of my life experiences are converging into something far greater than myself. To me, it all now makes sense.

Each and every thing we do to each other, no matter how small, makes a difference, either good or bad. Everyone belongs, everything belongs, all lives matter, all life matters, each and every one. As St. Francis recognized in the 1100 and 1200s, we are not only connected to the natural world and each other, but we are related, brothers and sisters all.
