Our Founding Story

We founded Oyama based on our personal experiences and challenges with accessing mental health care when we and our loved ones needed it  the most.

We believe psychotherapy is a resource that everyone should have in their pocket to understand themselves better and to help them cope with life's challenges.

Therefore, we’ve embarked on a journey to provide you with these evidence-based psychological tools.

Oyama means big mountain in Japanese, which guides us in many ways. We want everyone to be able to access evidence-based tools from psychology to be stable like a mountain throughout the storms of life.

Enabling individuals to become balanced humans.

A dedicated team building the future 

Team Oyama consists of the best kind of passionate, professional and positive people that all work to make mental well-being part of everyday lives. Our team consist of psychologists and mental health professionals, as well as tech, communication, marketing, legal, customer experience, and social media wizards.  

And we want you to join our mission.
