Dr. Jonathan Edward Rosero was born in Washington, D.C. and raised in Forestville, Maryland. He was introduced to medicine at an early age. His Afro-Latino father, the late Dr. Ecar H. Rosero, was a board-certified surgeon who came to the United States from Colombia and completed training at Howard University Hospital, going on to serve in the Medical Corps of the United States Army and at Saint Elizabeth's Hospital in Washington, D.C. His mother, the late Martha Wright Rosero, was a radiologic technologist. Jonathan's parents were his earliest sources of inspiration. But it was his love of animals that ultimately guided him to the profession of veterinary medicine.
A graduate of Forestville’s Mount Calvary Catholic School (Class of 1995) and Bishop McNamara High School (Class of 1999), Jonathan continued his education at North Carolina Agricultural and Technical State University, earning the Bachelor of Science in Laboratory Animal Science magna cum laude in 2003. Jonathan realized his childhood dream of becoming a veterinarian when he graduated from the Tuskegee University College of Veterinary Medicine in 2009. He returned to Maryland and began his career in private practice later that year, providing medical care for pets in Prince George’s County and Charles County.
In 2011, Jonathan answered the nation’s call to service, earning a direct commission as a first lieutenant in the Veterinary Corps of the United States Army Reserve. In 2020, then Captain Jonathan Rosero deployed to Afghanistan with the First Armored Division out of Fort Bliss, Texas in support of the NATO Resolute Support mission and Operation Freedom's Sentinel. Shortly after his return to the United States, he was promoted to the rank of major, and, in October of 2020, became the first African American and Afro-Latino to command the 147th Medical Detachment for Veterinary Service Support headquartered at Joint Base McGuire Dix Lakehurst. Jonathan has also served with the 422nd Medical Detachment for Veterinary Services, the 338th Medical Brigade, the 48th Combat Support Hospital, and the 450th Civil Affairs Battalion (Airborne). His military awards include: The Army Commendation Medal, the Army Achievement Medal, the Afghanistan Campaign Medal, and the Global War on Terrorism Service Medal.
Jonathan continues to live his dreams of being a veterinarian and soldier. His greatest passion, however, is mentoring and speaking to young people about veterinary medicine and the importance of a solid education. He is a guest speaker at schools as well as summer youth programs, and was even given the honor of speaking to a group of Daisies (future Girl Scouts).
Jonathan is a member of the Mount Calvary Baptist Church in Lanham, Maryland, Phi Beta Sigma Fraternity, Incorporated, and the Maryland Veterinary Medical Association. He resides in Forestville, Maryland, which has been his home for more than 40 years.
