Our Mountain Guides
The professionals at California and International Alpine Guides
are dedicated to providing you a safe and memorable alpine
experience. Owner/Director Dave Miller has a tight-knit team of International and California mountain guides that are hired based on their outgoing
and friendly personalities, their formal training, and their dedication to the profession
of mountain guiding.
How to choose a mountain guide:
For any mountain guiding, we highly recommend you look for guides that are certified and trained by the American Mountain Guides Association (AMGA). The AMGA is the standard in the United States for training and certification of mountain guides. It is not only the leading organization for training mountain guides in the United States, it is the only one that is recognized internationally. While there are some other upstart guide certification organizations as well as outdoor education companies with their own certifications, the AMGA is the only mountain guiding organization in the United States that is recognized by the International Federation of Mountain Guides (IFMGA).
Would you choose a dentist or an attorney with no standardized formal training or certification? Then why chose a mountain guide, with whom you place your well being, with no formal technical training?
For trekking and backpacking it's important you choose a professional who is familiar with the area and the culture in which they are guiding.
AMGA Certification
All of our technical mountain guides have
undergone training through the AMGA and many are certified
by the AMGA. Unlike most first world countries, certification in the United States is a voluntary
process instead of a mandatory requirement that involves a series of 8-10 day training courses
followed by 6-10 day certification mountain guiding exams.
It is a rigorous process that represents a higher level
of mountain guiding.
IFMGA/UIAGM Certification
The International Federation of Mountain Guides
(IFMGA, or UIAGM by it's French acronym) certification represents
the highest level of mountain guide certification in the
world. It is a process that rivals or exceeds a common graduate
degree in both time and money commitments. IFMGA/UIAGM mountain
guides have been through a 4-6 year process that involves
over 50 days of guide's training and 24 days of examination
in all three disciplines - rock, alpine and ski. A fully certified IFMGA/UIAGM mountain
guide is qualified to guide any terrain, anywhere in the
world in which they have experience, whether on foot or skis. I
At California Alpine Guides you know what
you're getting - friendly, personable & professional
mountain guides who will lead you effeciently & safely
through the mountains and on the rocks.

I went to college in Missoula, Montana (a place I may always call home?) at the University of Montana and got a degree in Recreation Management–Nature-based Tourism".
