Pensiri Matchachan, lovingly known as Waree, is a highly experienced massage therapist and teacher. With certifications from the Thai Ministry of Public Health in Thai Massage and Traditional Midwifery, she has spent over 15 years refining her craft and sharing her knowledge not only with local, but as well with students from various parts of the world.

Waree began her journey of learning and working with the art of Thai massage in 2010.  Starting her journey in southern Thailand, Waree began her practice in Chumphon and Krabi provinces before pursuing a formal Thai massage instructor course in Bangkok. 

She later relocated to Chiang Mai, where she trained under the guidance of Cooky, the owner of Loi Khroh Massage School. There, Waree worked as a massage therapist and instructor, specializing in Thai massage, abdominal massage, and other modalities. She was honored to teach in the school's Thai massage instructor program.

After four years, Waree decided to further her expertise in abdominal and Karsai (genital) massage through private training with the renowned teacher, Khun Ni. Upon completing her studies, she worked closely with Khun Ni as a teaching assistant for a period of time before establishing her own practice, working independently from her home ever since.

She has remained passionately committed to studying various types of massage, a dedication that continues to this day. Alongside formal education in the field, Waree deeply admires and respects traditional folk healers who use unique and diverse massage techniques.

Each year, she dedicates time to traveling across Thailand in search of revered teachers and masters. (This is how she met Dr Bai). Waree believes that simply accumulating certificates in a personal portfolio is not always proof of a profound understanding of this sacred art.

Her inspiration also stems from a childhood spent in a family of traditional healers. Although many of her ancestors passed away while she was too young to inherit their knowledge, those memories left a lasting impression. Over time, her life's path naturally led her back to her roots.

Additionally, Waree's personal health challenges in recent years have provided her with invaluable opportunities to learn and heal herself in extraordinary ways, further deepening her understanding of the healing arts.

Waree is known for her passion for healing arts, combining technical expertise with a caring and hands-on approach. She believes in the transformative power of touch and approaches each session with mindfulness, care and focus on individual needs of her clients.

Waree is now collaborating with Dr. Bai, and since February 2025 they have been leading massage classes together with great success. These classes follow Dr. Bai’s refined methods, with Waree co-teaching in seamless alignment.

Following the departure of her former mentor, Khun Ni, Waree sought a deeper spiritual connection with a true master to continue guiding her path. She has now found this in Dr. Bai. From here onward, she is dedicated to preserving and sharing his methods, whether or not he continues to teach alongside her.

Based in Koh Phangan and Pai Thailand, she offers a blend of Thai traditional and contemporary therapies that promote self-healing and well-being.

Her treatments integrate these practices with a modern detox twist, creating highly personalized and effective therapeutic experiences.

Waree sees massage as a form of "movement meditation" that combines skillful techniques with delicacy and care. Her sessions are designed to alleviate physical ailments while fostering deep relaxation and self-healing.

Every treatment is thoughtfully customized, incorporating elements from her wide-ranging practice to suit the specific needs of her clients.

As a teacher, Waree is eager to share her knowledge and promot Thai healing traditions worldwide. She views teaching as an act of merit, spreading awareness of alternative ways to support health alongside conventional medicine.

Her teaching approach emphasizes:

• Hands-on guidance with personalized feedback

• Empowering students to feel confident in their skills

• A focus on humility, gratitude and openness as key values in Thai massage philosophy

Waree is dedicated to her students' success and remains available to answer questions and provide support even after they complete their courses. Her enthusiasm and expertise inspire confidence and joy.

Waree and Doctor Bai- a Journey of Destiny

The beginning of Waree’s deep respect for Dr. Bai’s healing ability began around 16 years ago.

At that time, Waree suffered from symptoms resembling leukemia. She was in a situation where modern medical treatment was not possible. A friend recommended a traditional healer. With her six-year-old son by her side, Waree made the journey to find him on a small island in Krabi province.

The healer used only his bare hands, moving them along her back without even touching, until he discovered the root cause of her illness. He then prepared a herbal remedy with only three ingredients, infused it with sacred chants, and instructed Waree to boil and drink it herself—along with guidance for a new way of living.

Waree followed his advice. After finishing the decoction, within just three months, the frightening symptoms vanished without a trace.

In the darkness of life, suddenly, a glimmer of light broke through—guiding her toward survival.

In 2023, Waree once again fell gravely ill with a chronic condition that affected nearly every organ—blood, lymph, and even the brain after a severe head injury. She sought treatment from a folk healer in Chiang Mai and improved somewhat, but she still felt her life was running short. So she moved back to Koh Phangan, to be close to family and her mother in what she thought might be the last stretch of her life.

Still, her body longed for the care of a true traditional healer—though she did not know where to find one.

When life reaches the edge of despair, only destiny and the merit we carry can guide the way.

One day, Waree traveled to Krabi after hearing from a fellow Thai traditional medicine student that there would be a course on Kasai massage, rooted in the healing traditions of the sea gypsies.

And there, after more than sixteen years, she finally met the healer she had longed to thank all along—

Traditional Thai Medicine Master Hamin Wangsabu, known to many as Doctor Bai, the lecturer of that very course.

No words could describe Waree’s feelings at that moment.

Coincidence does not exist…

After that, Waree continued private studies of Kasai therapy with him. Inspired, she dreamed of introducing Dr. Bai’s wisdom to the world. She invited him to Koh Phangan to co-teach massage to international students. He accepted.

At that moment, Waree felt she was the luckiest person alive—to gain not only a teacher deeply skilled in ancient healing, but also a personal healer who cared for her health and gradually restored her strength.

As long as we strive to rise like a lotus above the water to greet the light, the light will recognize us and reach down to lift us higher.

From the time of their reunion, Dr. Bai showed great kindness and trust in Waree.

He once told her:

“I seek students who hold true faith, who believe and honor the ancient ways of healing.

Waree, you had the courage to entrust your very life to this path.

For this reason, I wish you to be among those who will carry on this lineage in the ways you are able.”

Thus, a sacred bond was woven—threads of teacher and student, heart to heart.

With pride and reverence, Waree bows before Master Hamin Wangsabu:

“I vow to uphold and carry forward the healing science you wish to preserve,

so it may be seen by the world and passed on to future generations.

I will do my best—until my life comes to its end.”

Even when this life concludes,

every ending becomes the foundation of the life to come.

With deepest respect and gratitude,

From Waree, to Doctor Bai
