Steve Smith


Steve grew up in Danville and has been an avid hiker and outdoor enthusiast his whole life. He is a docent, hike leader, back-country rover, leader of the Maintenance Volunteer Group, and member of the Trash Removal Project. He began volunteering on the mountain after completing a quest to hike all 162 miles of trails within the park.

Mike Brandy

Vice President

Mike is always drawn to the outdoors for inspiration and renewal.  As a Mount Diablo State Park volunteer for the last four years, he is currently engaged in co-managing the Mitchell Canyon Visitor Center, always trying to enhance the docent training and the visitor experience to the park.  He also volunteers on the Trash Removal Project (TRP) team.  He usually cycles or hikes every week on the mountain.

Dan Fitzgerald


Dan grew up in Concord with a view of the mountain and spent some time exploring it with Michael Marchiano. When he retired, Dan completed the State Parks volunteer training and became an active member of the Trash Removal Project and a visitor center and roving docent. Dan also enjoys nature photography.

Dan Sandri


Dan has lived in the East Bay for nearly all of his life, and Mt. Diablo has always been his favorite hiking place. Dan has a B. S. degree in Entomology and enjoys observing and photographing insects, birds, reptiles, as well as other plant and animal life. Upon retirement, Dan became a volunteer at Mitchell Canyon Visitor Center, a member of the Native Plant Garden team, and a back-country rover. Dan enjoys interacting with visitors, learning and writing.

Mark Brauer

Mark has lived in the East Bay for the last 35 years and has enjoyed hiking at Mount Diablo since he moved here. For the past six years he has volunteered his time as a docent and as a rover at Mount Diablo.  He particularly enjoys interacting with the park's visitors and helping them discover the best places to visit in the park. Mark set himself the goal in 2013 to hike every trail in Alameda and Contra Costa counties and after 8 years completed that task.  Of all the parks and open spaces in the East Bay he finds the most enjoyment from visiting Mount Diablo.

Julie Braun Martin

Julie, an educator for many years with a passion for conservation and serving youth, enjoys walking on the mountain and serving at Mitchell Canyon and assisting with publications.

Terese Dixon

Tere has lived at the base of Mount Diablo for nearly 40 years and has hiked and biked the trails of Mount Diablo State Park throughout that time. Currently serving as the Webmaster for the  MDIA website , Tere is also a State Park volunteer, and is a California Naturalist. Other than cycling with her husband, Tere enjoys working in her dry garden and birding. 

Staci Hobbet

Staci is a Natural History Docent in Mount Diablo State Park, the lead of the Peregrine Team in Pine Canyon, and a graduate of the California Naturalist Program. Her focus is on natural history interpretation and outreach.

Linda Kwong

Linda has lived in Alamo since 1997. Her connection to the mountain started after a neighbor took her on a bike ride to the Summit over 7 years ago. Now she is a regular visitor on the mountain, often riding 3-4 days per week. Photographing all four seasons and engaging with both the park visitors and staff are her favorite activities. Her goal is for all park visitors to have a safe, memorable and fun experience during their visit on Mount Diablo. 

Leslie Contreras

Living in the shadow of Mount Diablo all her life, Leslie has always had a passion for the mountain. She contributes to MDIA as the event coordinator for the hiking program and as co-manager of the Mitchell Canyon Visitor Center.

Carol Lane

Carol is a retired Registered Nurse who loves to be active and find interesting things out in nature. She is an active trail maintenance volunteer and sees trail work as a way to give back for the enjoyment that she experienced as a trail runner.

Dick Nicoll

A long time local resident, Dick loves everything outdoors.  He coordinates publications, serves at Mitchell Canyon, works on the Trash Removal Project, and organizes road repairs.  He has completed the California Naturalist Program. 

Harry York

Harry has been hiking in the Bay Area and Northern California since grade school. In the last few years with more time, he has hiked in most of the east bay parks and now as a docent for MDIA, has hiked almost every trail on Mt Diablo.
