从1931年至1934年,他在明尼苏达州罗彻斯特的梅奥医院(Mayo Clinic)工作。1934年,他再度回到中国,担任传教医生,接替万德生院长(Percy T Watson),担任山西汾阳医院院长[4]。1937年中日战争爆发后,周以德体验到颠沛流离的战乱生活,他护送妻女到汉口乘坐飞机离开中国时,目睹日军无差别轰炸人口稠密的居民区,然后又冒险只身返回汾阳。1938年2月,日军占领汾阳,医院面临困难,经周以德出面交涉,日军同意撤出医院,而他本人则被限制人身自由。直至同年7月,周以德因帮助一名日军军官治好了性病,才获准返美[5][6][7],回到明尼苏达州。
1981年,他获得总统自由勋章(美国最高的公民荣誉)。在整个1970年代和1980年代,他在华盛顿哥伦比亚特区积极参与了反对共产主义入侵委员会(Council Against Communist Aggression)。
