Equuscience™ Master Class:

A trauma-informed and evidence-based lens on horse-human relationships

Herd of horses in the mountains in Iceland

Back by popular demand!

**Late registrants welcome – final deadline to join the 2023 master class is August 10, 2023 at 11:59pm Pacific**
Sarah and Dr. Peters are excited to be running their master class again in 2023. This educational course offers an accessible overview of a number of important topics grounded in the latest neuroscience and research, along with best and promising practices from the fields of psychology, trauma treatment, and ethology, to help you better understand you and your equine(s). Learning to recognize how adversity and trauma impact the brain, nervous system, behaviour, relationships, and overall functioning, as well as concrete tools, frameworks, principles, and next steps to help start the process of transformation for you and your equine(s) are the main goals of the program. Trauma in humans, trauma in equines, and the particular intersection of the two (equestrian trauma) will be explored through a compassionate lens that brings in awareness of somatics, attachment, psychophysiology, and interspecies neurobiology.

Payment is by credit card, and the link is at the bottom of the page to register. Registration is on a first come, first served basis. We cannot offer payment instalment plans because payment in full is required in order to reserve your spot in the course. Payment by credit card allows participants to pay off the course registration in instalments in a customized way that works for their respective situations.

Student Cancellations

You are eligible for a 100% refund if cancelling more than 90 days before the first day of the master class (May 27), and a 50% refund if cancelling between 60-89 days before the first day of the webinar or seminar. A $100 CAD administrative fee is applied to process refunds. No refunds are possible for cancellations that occur in the 59 days before the first day of the webinar or seminar.

Instructor Cancellations

On occasion, a module from the master class may be affected by reasons beyond our control, such as due to instructor illness or emergency or a technical issue (e.g., an internet, power, or Zoom service outage). In these cases, we may need to reschedule a module. Because the modules are recorded to accommodate the many students who cannot attend live, no refunds will be provided in the event that a particular module needs to be rescheduled, as the content will still be made available.

If the master class program needs to be cancelled in its entirety, two options are possible: (1) you may defer your registration and the entirety of your registration fee payment (without penalty or administrative fees, at no additional cost) to a future master class program taking place in the next year (from the start date of the event in question that was cancelled or rescheduled). We are considering additional dates pending demand, but we can make no guarantees about the availability or dates of future offerings. Or (2) if you prefer, we will issue a 100% refund due to the inconvenience (if the program had to be rescheduled entirely) or a partial refund (prorated based on the modules that occurred before the interruption).
