Graduate reviews and experiences
We publish only reviews whose author, completed course and consent to publish have been confirmed. We do not create anonymous or promotional quotes.
Last updated: 9 September 2026
We collect verified graduate reviews after courses finish and publish them on this page once the author, the course and consent are confirmed. Current participant material — photos, video and comments from sessions — is on the Instagram accounts of Olena Groza and OG Cosmetology. Once the Google Business Profile is live we will add a link to Google Maps ratings here.
How we verify reviews
Before we publish a review we confirm each of the points below, so you can be sure you are reading a real participant's account of a specific course, not a marketing text.
- name or an agreed form of anonymisation
- the completed course and approximate date
- confirmation of attendance on the OG Academy side
- written consent to publish the text, photo and any link
- the option to withdraw consent at any time
