Steve Curtiss, Owner and President.

I grew up in a small rural town in Wisconsin and attended the University of Wisconsin in Madison. In 1992, I received a BS in Landscape Architecture from the University of Wisconsin. From there I moved to Crested Butte following my dreams of becoming a ski bum. I started working for Rocky Mountain Trees in the summer of 1990, and after graduation, I moved to Crested Butte permanently. In 1996 my wife Nel and I became owners of the company and have run it ever since.

Since moving here, I have achieved certifications in the Colorado Certified Nursery Professional, Certified Landscape Technician, and Landscape Irrigation Auditor. I also serve on the Board of Riverland Industrial Park, as well as the Design Review Committee for Skyland Residential Community in Crested Butte.

I also enjoy a multitude of outdoor activities including mountain biking, skiing (many kinds), hockey, hiking, hunting, fishing, and spending time with my wife Nel, and my two boys Dylan and Cameron.

I was recruited to work at Crested Butte Mountain Resort in 1989 after receiving a degree in Business/Marketing from Michigan State University. I fell in love with the Gunnison Valley and began working at RMTL in 1993 with my husband, Steve.  We have two boys, Dylan and Cameron and love to ski, bike and play hockey.  I have achieved my certifications for the Certified Colorado Nursery Professional, Advanced Master Gardener and Permaculture Design Consultant.  I love to teach what I have learned about composting, organics and ways we can help preserve our special valley.

Batman has Alfred. Alfred serves as Bruce Wayne’s tireless valet, assistant, butler, confidant, best friend, and surrogate father figure. Alfred runs the day-to-day operations of Wayne Manor and maintains much of the equipment of the Batcave beneath it. He’s got friends in low and high places. Alfred provides much needed comic relief and is always at the ready for when the Bat Phone rings to assist Batman with whatever he may need.

Rocky Mountain Trees has Hailee.

As a child, born in Crested Butte I found a profound love for the environment and the beautiful Gunnison Valley. I fell in love with the intense exposure Crested Butte offered me to the backcountry and the forever changing environment I grew up in. I joined the Rocky Mountain Trees team in the summer of 2010, while in high school, and continued to progress through various positions in the company. In 2013 I moved to Washington State for a year to play junior hockey where I realized the sunny state of Colorado was where I wanted to be located. I moved to Fort Collins, Colorado where I attended Colorado State University and majored in Natural Resource Management and minored in Environmental Sustainability. I carried this knowledge back to Crested Butte with me in 2018, where I continue my career at Rocky Mountain Trees as Landscape Manager. I plan to continue my landscape career at RMTL and show my appreciation to this company and valley that presented me with so much as a child. The arrival of my son Jack in March of 2021 constantly pushes me to keep this valley pristine for the next generation to come. – “GO AVS”

Growing up in the Midwest Mark found a great appreciation for our environment. After bouncing around he settled in Kansas City where he became an ISA Certified Arborist and started honing his skills as a municipal arborist and horticulturalist.  He was the City Forester and Horticulturalist for the City of Emporia Kansas for 3 years before returning to the Gunnison Valley.  Mark joined Rocky Mountain Trees in the spring of 2019 and is our knowledgeable Maintenance Department Manager.  Mark is also a self-taught welder and sculptor whose beautiful art is on display and for sale in our garden center. Mark looks forward to serving and educating our clients in this amazing valley we call home for years to come.

I lived in Kremmling, Colorado until I was 10 years old, then my family moved to Las Vegas, Nevada where I lived until I graduated high school. Being raised between two distinct communities helped shape me into the person I am today. It also instilled in me a great respect for understanding different perspectives and the varied ways people interact with the environment and society around them. After high school I attended the University of Nevada Reno, where I graduated with a Bachelor’s of Science in Environmental Science and Forestry Management. In May of 2018 I knew two things, I wanted to move back to Colorado, and to be closer to my nieces and nephews. So I moved to the Gunnison Valley to be near my family and finally be back living in the Rocky Mountains. I was then lucky enough to find my second home at Rocky Mountain Trees and Landscaping in the spring of 2019, where I can use my experience and knowledge to create a better tomorrow for our clients and our valley. I love being outdoors as much as possible and have a passion for preserving the seas, trees, bees and everything in between.

A southern girl always looking for the next adventure. I grew up in Tennessee but was lucky enough to move to Colorado to study at Colorado State University. While in school, I picked up a job at a local nursery. There I gained extensive plant knowledge and identification skills. After I graduated, this turned into a full-time position but while I loved where I worked on the Front Range, I didn’t really love where I lived. After a couple winters spent here in Crested Butte during my off-season, I decided to take a jump and now I have both – I love what I do for a living, AND I love where I live. How lucky am I!

Since moving here, I have learned so much about our high-altitude growing environment and love sharing my knowledge with customers. I enjoy spending my time out in the backcountry – camping, hunting and fishing, you name it. I feel closer to the lifestyle I’ve always dreamed of and feel so blessed to call this beautiful valley home.
