About Us
AT U Dental Co., Ltd. was founded with a shared vision of developing accessible and high-quality dental care services that meet the evolving needs of patients. This vision was spearheaded by Dr. Nattika Whannasrichan (Dr. Nat, COO), who earned her Doctor of Dental Surgery degree from the Faculty of Dentistry at Western University in 2018. Following her graduation, Dr. Nat embarked on her career as a part-time dentist at multiple clinics to build hands-on experience in diagnostics and dental procedures. She further enhanced her professional skills through advanced training courses in specialized fields, including dental implants, traditional orthodontics, and clear aligners.

In 2020, Dr. Nat opened her first private practice, Nattist Dental Clinic. However, the outbreak of COVID-19 presented significant challenges to the dental industry, as healthcare businesses had to adapt to strict health protocols that limited in-clinic patient visits.
During this period, Dr. Nattika Whannasrichan identified an opportunity to expand dental care accessibility through a strategic partnership with Mr. Thatchawee Suwanpanya (CEO), a seasoned professional with over 10 years of experience in engineering and business operations. Mr. Thatchawee graduated from the Faculty of Engineering, majoring in Electrical Engineering, at Kasetsart University, Sriracha Campus. He is also the founder of AT Lift Engineering & Service Co., Ltd., a company specializing in elevator systems and automated parking solutions.
The alignment of their business visions led to the development of an innovative approach to dental care. They sought to make dental services more convenient and accessible by leveraging mobile dental units, a concept that extended care beyond the confines of traditional dental clinics. This mobile model not only overcame operational challenges during the COVID-19 pandemic but also introduced a more flexible patient care experience.
With a commitment to delivering exceptional and accessible dental services, AT U Dental Co., Ltd. was officially established on November 22, 2021. The company offers a comprehensive range of dental care solutions, including in-clinic treatments and mobile dental services. Today, AT U Dental operates five dental clinics and manages four mobile dental units, supported by a robust network of 25 partner clinics nationwide that collaborate to provide mobile services.
Driven by a dedication to service innovation and patient-centered care, AT U Dental Co., Ltd. continues to enhance the accessibility and quality of dental treatment. The company has established itself as a trusted leader in Thailand’s dental care industry by offering a seamless, high-standard dental experience for individuals and organizations alike.
