Fill out the form with all your details, such as first name, last name, email address, and phone number, then proceed with the payment.

Live course registrations follow a tiered system with progressive pricing:
  • Early Bird Rate: up to 30 days before the course starts, with a 20% discount
  • Standard Rate: from 30 days before until registration closes
  • Registration Deadline: 5 days before the course starts
We recommend enrolling as early as possible to take advantage of the Early Bird discount and secure your spot, as courses have a limited number of participants.

Once your enrollment is complete, I will promptly schedule a date, which will be set with at least 30 days' notice before the course begins, to allow easier planning for all participants. This approach allows me to offer flexible and personalized solutions tailored to the actual needs of the attendees.
