Pharmacist, CPHQ, CHQO, Quality Coordinator, Chemotherapy Preparation incharge. Graduated pharmacy school in 2009 I stood with my classmates as we recited the “Oath of a Pharmacist” in. There is one particular vow that stood out to me as we recited the Oath and I embrace this vow, “I will apply my knowledge, experience, and skills to the best of my ability to assure optimal outcomes for my patients.” I love being a pharmacist because it allows me to use my knowledge, abilities, and talents to improve patient outcomes in the community hospital in which I am employed as the pharmacy clinical coordinator.
