Mountain Medics was formed in 2014 as a response to the growing need for on-scene medical support for wildland firefighters. After several severe fire seasons in northern California, the Mountain Medics team decided to devote themselves to more creative healthcare delivery methods than can be traditionally found in hospital settings. We are proudly based out of Dunsmuir, California, on the edge of the wildland urban interface. Siskiyou County is one of the most economically disadvantaged counties in California and is disproportionately affected by wildfire.

The availability of satellite internet and wireless technologies allows all Mountain Medics units to remain in constant communication with trained emergency medicine physicians. We offer rugged mobile medical clinics and medical response tents staffed by fireline qualified medics, registered nurses, and midlevel providers. Our medical response teams are equipped to live and work in harsh conditions and carry a full complement of prescription medications, IV solutions, and wound care supplies. From basic life support through advanced diagnostic and treatment modalities including imaging, lab testing, and suturing, we let our clients decide what level of care to provide.

Mountain Medics Owners

Instead of bringing your personnel to the emergency department, bring the emergency department to them.

Chad McCall, RN-MICN, EMT-P

Co-founder, Chief Executive Officer

Chad grew up in Alaska at the base of the Talkeetna Mountains and generally spent his free time backcountry snowboarding, mountain biking and fishing. He relocated to Northern California in 1998 to teach environmental education.  After settling in Mount Shasta Chad started working for the local ambulance service as an EMT and became involved in ski patrol, mountain guiding, and search and rescue. After obtaining his paramedic certification, his first exposure to disaster medicine was triaging at the Astrodome after Hurricane Katrina. In 2004 he traveled to Pakistan after a major earthquake to set up and help staff several urgent care clinics. He has gone on to work throughout the states as a fire line paramedic and as a disaster paramedic with the National Guard and FEMA.  Chad sought additional training and became a registered nurse in 2013. He divides his time between running Mountain Medics and working as a RN-MICN in a local emergency department and ICU.

Aaron lives in rural Siskiyou county because he enjoys the natural surroundings and the community. He is an avid skier and paraglider pilot. He grew up in northern California and was largely a computer nerd, graduating from UC Berkeley with a Bachelor of Science in bioengineering. He spent several years living in Mount Shasta, California, skiing, climbing, and working occasional 9-5 jobs. After taking an EMT course and becoming involved in the local search and rescue organization, he decided to make  emergency medicine a career, eventually graduating from medical school in 2009. He completed a surgical internship and three years of residency training in emergency medicine. He is a practicing board-certified emergency physician working at a local critical-access emergency department. He is also a certified ultrasound technologist and is a strong supporter of the use of bedside ultrasound for rapid diagnosis and treatment.

Todd Wemmer, EMT-P

Co-founder, Chief Operations Officer

Todd grew up in Santa Rosa California, where he fell in love with the great outdoors. He spent most of his time rock climbing, mountain biking and back packing. After graduating high school, he found a job on a watershed restoration crew improving state parks in Sonoma County. This lead to a scholarship award for Todd and he decided to move to Mount Shasta for its unparalleled outdoor environment. Later he completed the CSFM fire fighter 1 academy and went on to earn his National Registry Paramedic license. Todd has worked several seasons as a wildland firefighter on hand and engine crews, and provided prehospital care on ground and air ambulances. He has also worked as a fireline paramedic on many large scale incidents, and provided fire prevention/first responder services for large movie productions.

Todd's experiences helped him develop a vision of improved healthcare access for rural residents and responders in need of medical care and transport. Mountain Medics is the result of this vision.
