Siam Rehab’s Milestones
May 2014 – Founded on Koh Samui
Siam Rehab was originally founded on the island of Koh Samui on May 5th, 2014. While the island’s natural beauty and tourist appeal were undeniable, we soon realized that its active party scene made early recovery more difficult for many of our clients. In addition, operating costs on the island were high—making treatment less accessible for people who genuinely needed help but couldn’t afford expensive private rehab.
January 2016 – Move to Chiang Rai
Based on what we learned in Samui, we made the decision to relocate. We chose to stay in Thailand—not only because of its affordability, but because we felt a strong connection to the culture and the people.
In Chiang Rai, Northern Thailand, we found exactly what we were looking for. Unlike the busy tourist hub of Chiang Mai, Chiang Rai is quiet, grounded, and better suited to our mission. It provides a peaceful, stable environment that supports the recovery process—away from nightlife, yet still close to international airports and excellent hospitals.
Being here also allows us to keep costs manageable, so that more people who need treatment can afford to get it.
January 2016 – Appointed Medical Director
Shortly after relocating to Chiang Rai, we began working with Dr. Nattapatt Sukkhosawat (Dr. Mark), who now serves as our full-time Medical Director. A practicing physician for over 19 years, Dr. Mark graduated from Chiang Mai University Medical School and completed his specialty training in psychiatry and addiction medicine at Suan Prung Psychiatric Hospital.
He is regularly on site at Siam Rehab, overseeing the medical needs of all clients throughout their stay. For cases requiring outpatient detox or additional medical support, Dr. Mark also works with his own clinic in town and collaborates closely with Kasemrad Sriburin Hospital—a respected private facility offering 24/7 emergency care, psychiatric services, and medical detoxification.
August 2018 – Name Changed to Siam Rehab
By mid-2018, it became clear that the name “Serenity” was too common—used by many unrelated rehab centers around the world. We needed a name that reflected our identity and stood apart.
Around the same time, we came across the legacy of Siam Rehab—a respected treatment center originally founded in the early 2010s by Australian therapist Tim Armstrong in Nakhon Sawan. Although that facility had since closed, the name remained meaningful within Thailand’s recovery community.
After careful discussion and reflection, we decided to adopt the name Siam Rehab for our own center. Our program, team, and values remained the same, but the new name allowed us to carry forward a respected identity while standing out with clarity and purpose.
November 2018 – Moved to new Facilities in Chiang Rai
In November 2018, we relocated to a newly developed campus in Chiang Rai, set amid lush jungle gardens and designed specifically for healing and recovery. The new facility includes upgraded accommodations, dedicated therapy spaces, and a fully equipped gym to support physical well-being as part of our holistic approach.
This move reinforced our long-term commitment: to provide high-quality, affordable addiction treatment in an environment that feels safe, focused, and supportive for every person who walks through our doors.
Siam Rehab Location
Siam Rehab is situated in Chiang Rai, Thailand
Siam Rehab is located about 30 minutes from Chiang Rai International Airport and 40 minutes from the city center—close enough for convenience, yet far enough to offer privacy and calm.
Set in a quiet rural area, our facility provides the space and stillness needed for focused recovery. At the same time, clients have regular opportunities to engage with the surrounding community through guided excursions, fitness activities, and cultural outings—striking a healthy balance between retreat and real-world connection.
Chiang Rai has proven to be an ideal location for addiction treatment in Thailand. It offers a rare balance: modern infrastructure—including excellent hospitals and an international airport—within a calm, non-touristic setting that naturally supports focused recovery.
Unlike cities such as Bangkok, Phuket, or Pattaya—where nightlife and easy access to substances are hard to avoid—Chiang Rai provides a quieter, more grounded environment. Clients are removed from common triggers and can fully engage in the recovery process without the distractions of high-tourism areas.
Our previous location on Koh Samui, while beautiful, posed challenges for early-stage recovery due to its party-heavy surroundings. By relocating to Chiang Rai, we not only gained a more supportive setting, but also lowered operating costs—allowing us to make our program more affordable and accessible to those who need it most.
Getting to Chiang Rai
For clients who would like additional travel assistance, Siam Rehab can arrange for a support staff member to meet you at Bangkok’s Suvarnabhumi Airport, assist with your domestic transfer, and coordinate a private taxi from Chiang Rai Airport to our facility. This optional service is available for an additional fee.
While many clients choose to book their own flights directly to Chiang Rai, we are always happy to help with logistics to make your arrival as smooth and stress-free as possible.
