About Marissa:

  • Marissa Pettit is a dedicated pharmacist with a passion for providing specialized care in the areas of Diabetes, Heart Failure, and Hypertension. She completed her education at Presbyterian College School of Pharmacy. She is a resident with the Tandem Health Pharmacy Residency program. This program is a collaborative partnership between Prisma Health/USC Family Medicine, the USC College of Pharmacy and Tandem Health.
  • Marissa's journey into medicine began at a young age with a strong desire to help people. Initially aspiring to become a doctor, she had a pivotal moment in high school when her health science teacher encouraged her to explore the field of pharmacy. Taking a job as a pharmacy technician at Wal-Mart, Marissa discovered her love for patient interactions and knew that being a pharmacist was her true calling.
  • If she had not pursued a career in medicine, Marissa's natural organizational skills would have led her to become a professional organizer, helping people create harmony and order in their homes.
  • Outside of her profession, Marissa finds joy in spending quality time with her family and friends. She particularly enjoys exploring the charming cities and beautiful beaches in the Charleston area.
  • One fascinating aspect of Marissa that not many people know is that she belongs to a large and tightly-knit extended family. Their bond is so strong that when they gather for a family vacation, they form an impressive group of nearly 20 people, drawing attention and smiles from others wherever they go.
  • Marissa hopes to leave a lasting legacy during her time at Tandem Health. As a pharmacist, she aims to further enhance her patient care skills and work towards breaking down barriers to healthcare for individuals residing in areas like Sumter.
