Cheston Wong PA-C

Internal Medicine | Westside

Physician Assistant Cheston Wong brings his easygoing demeanor to the GreenField team every day. He’s easy to talk to and a great listener, and his patients appreciate the extra time he spends addressing their concerns. 

Cheston has always been interested in both biological and social sciences and his position here at Greenfield allows him to bridge those interests. As a physician assistant, he works with his colleagues to provide primary care services that are coordinated, team-based, and personalized.  

He received his Master of Health Services from the University of California, Davis. That training in public health contributes to his understanding that a patient’s well-being extends beyond their physical health to their social and mental health. With that perspective in place, he is able to develop strong patient/provider relationships.

“I value establishing and maintaining robust relationships with my patients and believe that such partnerships allow for the delivery of informed and appropriate health care,” affirms Cheston.

Cheston also serves as GreenField’s clinical lead for the Collaborative Care Management Program. This specialized program assists patients who benefit from complex, collaborative care. Cheston works closely with patients and colleagues, overseeing the clinical workflow involved in implementing and maintaining the program’s recommendations. 

“The Collaborative Care Management Program here at GreenField allows our team of clinicians and support staff to review and discuss program enrollees’ chronic issues such as diabetes, hypertension, and depression. We help members incorporate lifestyle modifications and clinical recommendations when appropriate.”

Cheston works Monday through Friday at our Westside clinic. In his spare time, he enjoys trail running through Portland’s parks, hiking along the Gorge and coast, and trying new restaurants around town.
