Ton Athiwad Sanidwong Na Ayoodthayaa

Ton Athiwad Sanidwong Na Ayoodthayaa (Thai: ต้น อธิวัฒน์ สนิทวงศ์ ณ อยุธยา; born March 17, 1968) is a Thai actor whose career on Thai television began in the late 1980s and has produced more than 150 credits. In the 2026 Domundi TV historical Boys’ Love series Love Upon a Time he plays Lord Phichaiphakdi, rendered in Thai credits as Phraya Phichaiyaphakdi, the highest-ranking noble in the Ayutthaya-era storyline and one of the figures holding the truth about Klao’s disappearance.

He was born in Bangkok on March 17, 1968 and trained not as an actor but behind the camera, taking a photography and cinematography course at the institution recorded variously as Bangkok Technical College and, under its later name, Rajamangala University of Technology Krungthep. A Thai film database describes him as an actor and volunteer, and his profile carries community work alongside the screen credits.

His screen career began in 1987-1988 and has run continuously since, almost entirely in supporting and character parts rather than leads, the kind of career that makes an actor instantly recognisable to a domestic audience without ever making him a headline name. Notable entries include Lah (1994), Kassatriya (2003), Sarb Krasue (2018) and Phuea Mae Phae Bo Dai (2023), and his recent slate covers Pha Daeng Nang Ai (2025), Chao Khun Phi Kap E Nang Kham Duang (2025), Ubat Rak Ko Sawan (2026) and Heart Code (2026).

His family name carries its own history. Sanidwong Na Ayudhya is one of the royal-descendant surnames of the Chakri dynasty, granted to the descendants of Prince Wongsa Dhiraj Snid, and the “Na Ayudhya” suffix marks that lineage. It is a fitting coincidence for an actor cast as an Ayutthaya-era lord: the name itself points back to the old capital.

He is a Pisces, born in the year of the Monkey. Aside from the birth date, birthplace and training, very little personal detail about him has been published in nearly four decades of work: there is no verified agency, no social media account confirmed to him, and no interview on record carrying the personal-preference material that younger Thai actors routinely supply.
