She utilizes these skills to be an excellent pharmacist to her patients. She truly enjoys her field of work, and lives by her saying “Serving as a pharmacist is simply being myself.”
Dr. Nancy Vesoh, Pharmacist
Born in Cameroon, West Africa, I loved both medical research and the practice of medicine, because of how it impacts the state of wellbeing and quality of life. I would very quickly realize as a teenager while shadowing a missionary doctor that the site of blood was not my forte. All that passion got diverted into the other aspect of medicine; research and pharmaceuticals. I then pursued an undergrad degree in organic chemistry, worked in biotechnology, then obtained a doctorate degree in pharmacy at the university of Maryland, Baltimore.
If not at work, it would be salsa dancing or the Kitchen; making up recipes, trying new ones, and doing best part…eating.
