Pharmacist-In-Charge

I’m originally from Accra, Ghana. I graduated with a bachelor's in Pharmaceutical Sciences from The Massachusetts College of Pharmacy, Boston, in May 2020. I went on to earn my Doctorate in Pharmacy at the Massachusetts College of Pharmacy, Worcester, graduating in May 2023. My passion for pharmacy began in 2016 and has led me to work in various aspects of the pharmaceutical industry.

I look forward to bringing that experience to Sierra International Pharmaceutical Corporation. Sierra is a patient-centered company, and I am eager to get to know our patients. As the new Pharmacist in Charge, I hope to provide each and every one of our patients with elite service and solutions to any issues they may have. I am very down-to-earth and will make as much time for each patient as needed. In time, I hope to promote our patient-centered programs, such as our remote patient monitoring, and introduce new programs for the benefit of our patients. -Dr. Emmanuel Simpson, PharmD
