Dr. Boon Vanasin and a group of doctors founded Thonburi Hospital Co., Ltd. with a paid-up registered capital of 20 million baht on 13 August 1976. He chose Thonburi for the hospital location as there was no private hospital in the area while the only public hospital, Siriraj Hospital, was very crowded and lots of patients had to wait for a long time due to insufficient beds. The birth of Thonburi Hospital, which was aimed to provide excellent healthcare services, met demands of the growing number of patients.
