About

Dr. Gray grew up on a hog and grain farm in northern Iowa. She went into medicine in order to be constantly challenged and learning. Medicine also allows her to make a positive difference in people’s lives daily. She practices a full range of family medicine, with special interests in travel medicine, immunizations, obesity medicine, public health and preventative care. She teaches medical students and is involved with our local public health department. She volunteers at her church, her children’s school, and also remains involved with agriculture. 

Her husband, Dr. Tim Mulholland, is a urologist with MercyOne North Iowa Urology.
