Dr. Wallman grew up on a farm near Filley, Nebraska and graduated from Freeman High School in 2013. He thoroughly enjoyed helping his parents with crop farming and raising livestock (including cows, chickens, and goats through 4-H and FFA), but knew from an early age that he always wanted to be a physician. He attended the University of Nebraska at Lincoln and graduated with his Bachelor of Science Degree in Biochemistry in 2017. He then attended medical school in Omaha at the University of Nebraska Medical Center (UNMC) and graduated in 2021. Following medical school, he continued his medical training at UNMC with his family medicine residency program, joining the advanced rural training program in 2020. He finished residency in June 2024 just prior to starting his employment at Fillmore County Medical Center in September. He enjoys practicing full scope family medicine, including outpatient and inpatient care, emergency department coverage, and obstetrics.
