What is Violence Dynamics?
Simply put, Violence Dynamics is the study of violence and the people who inflict violence on others. Understanding how violence happens, how your body deals with violence, and how to choose and deploy an appropriate level of force in response is crucial if you want to survive a violent encounter. Real violence happens faster and harder than most people’s training takes into account.
The Violence Dynamics seminar (VioDy) takes principles and concepts that usually take professional users of force years to comprehend and distills them into a common language for dealing with violence.
Created in Minnesota in 2010 by Kasey Keckeisen, Rory Miller, and Marc MacYoung, VioDy has become an annual event, with spin-off seminars in Edmonton, AB; Oakland, CA; and Ashburn, VA. We brought VioDy to Vancouver for the first time in 2017! This page serves as an archive of that first event. For updates on future events of this nature, sign up for our VioDy-specific newsletter:
VioDy Vancouver took place on: Friday, Dec 1st to Sunday, Dec 3rd, at the Rhodes Wellness College on the corner of Howe St. & Helmcken St. It's an easy walk from both SkyTrain lines, and close to some of the best lunch spots in the city. Courses ran from 9:00am to 6:00pm.

Are you interested in sponsoring VioDy Vancouver? We have a wide variety of sponsorship packages available to fit your needs. Email email@example.com for more information.
I've never done martial arts, but I'm interested in self defense. Should I still come?
Yes! VioDy has something for everyone, at all skill levels. You will learn a ton, and have a lot of fun.
I'm not a law enforcement officer or use of force professional. Can I come?
Yes! You do not need to be a professional to enjoy the benefits of the seminar.
I'm an 8th degree black belt/pro MMA fighter. Should I bother?
Yes! First of all, self defense and violence dynamics are very different than traditional (or non-traditional) martial arts. Second, you wouldn't have gotten that good without realizing that there's always something new to learn about a subject you thought you knew well. Third, VioDy covers a lot of non-physical skills too. Fourth, there will be some advanced classes, as well as opportunities for private training with the instructors. Fifth, seriously, these are some of the best teachers on the continent, all together for the very first time. Why would you not?
Can I sponsor an attendee?
Heck, yes! This is still a Valkyrie event, after all - people helping each other is the cat's pyjamas and we will always facilitate it. Send us an email if you would like to provide any level of personal sponsorship, or to inquire if there are any sponsored spots available.
Can I volunteer?
Heck, yes! We'll need helpers to wrangle attendees, buzz people in, make sure the instructors remember to eat/drink, etc. Send us an email if you would like to volunteer.
I've bought my pass. Do I need to pre-register for individual courses?
No, but you might want to. There will be two courses running at once for most of the weekend, and space will be limited, so if there are specific courses you for sure don't want to miss, it'll be a good idea to reserve a spot. If you're happy to go with the flow and soak up the knowledge, throw your cares into the wind and drop into whichever one isn't full on the day.
*If you have a 1-day or 2-day pass, the membership will default to starting on Dec 1st. Please let us know which day(s) you plan on attending so we can set the dates correctly so you can pre-register.
Can I register for a single course?
You bet! Registrations for individual courses are now open - just go to the calendar page and fast-forward to December. Costs will vary.
Do you have designated course tracks that I have to sign up for?
No. Some of the courses cover material that's a bit more advanced, while some focus on basics, but all are open to everybody. We've tried to pair them up in the schedule to give you good options - you're gonna have to make some hard decisions though! To help you plan, anything in Room 1 is a physical class, and Room 2 & 3 are mostly lecture-based.
Can I book private sessions with the instructors when they're not teaching?
Yes! Details are still being ironed out, but most of the instructors will be available for at least a few private sessions in their off-time.
I'm coming from out of town. Where should I stay?
Since it's right downtown, the venue is literally surrounded by hotels. Here a list of what's available in a two block radius:
Ramada Vancouver Downtown (~$125/night)
Century Plaza Hotel (~$130/night)
Best Western Chateau Granville (~$155/night)
Holiday Inn Hotel & Suites Downtown Vancouver (~$175/night) - this one's right across the street
Comfort Inn Downtown (~$175/night)
Marriott Residence Inn (~$185/night)
Howard Johnson Vancouver Downtown (~$225/night)
Sheraton Vancouver Wall Centre (~$235/night)
It is very easy to get to by public transit, so if you find another better/cheaper place to stay elsewhere you'll be fine as long as it's close to any of the SkyTrain lines.
