Theo de Vries – Founder – Manging Director.
The Diamond is founded by Theo de Vries; a pioneer in the rehab industry. Seven years ago, he started one of Thailand’s most successful rehab centers in Northern Thailand. When he took a 6 six months sabbatical in October 2019, he decided that it’s time to create something new, something special that doesn’t exist in Thailand for an affordable price. After a few months of searching for the right location, he found – as he calls it himself – The Diamond. Theo is 43 years old, married and has three children. Theo is in recovery himself and knows from first hand how it feels to overcome addiction and underlying issues. Theo is always willing to share his life story with the clients and be a positive influence towards their recovery. When you call the Diamond, you will speak to Theo personally and he will answer all the questions you may have directly. Theo’s life motto is: “It’s never too late to make a change.”
