[1] After a brief appointment as chief urologist, commissioned by the Army during WWII, at the Urology Section of the 28th General Hospital in Osaka, Japan, he and his wife started a private family medicine practice in Sumas, Washington.

Over time, the business expanded and the hours became demanding so they decided to return to California and establish a larger practice with more physicians, nurses, and dedicated staff in Antioch.

[2] He continued his understanding of angiography at the Cleveland Clinic under Dr. F. Mason Sones, who focused on arteriography via the brachial artery and then at the University of Lund in Sweden under the guidance of radiologist Dr. Sven Seldinger.

[3] He brought these new-found techniques back to UOMS in 1966 and started working to simplify the procedure to perform it without the use of general anesthesia to decrease the complications and risk associated.

At this time, he was given the post of associate professor of radiology which came with the benefits of a newly fitted laboratory where he worked with colleagues to utilize these techniques to develop selective coronary catheterization.

He took this offer and moved with his wife back to California, and took the positions of chair of the Department of Radiation Sciences and director of the cardiovascular laboratories from 1970–1978, during which time his labs were frequented by physicians from around the world.
