Biology Appointment Tutors

Morgan Dorsey, Biology

Hi, y'all! My name is Morgan Dorsey, and I'm a senior pursuing a major in psychology with a minor in biology. Throughout my academic journey, biology has always been my favorite subject in school, fueling my curiosity about the intricate workings of life. I am currently on the pre-medicine track, aiming to merge my passion for understanding the mind and body. I am an East Coast baby at heart, originally from Fayetteville, North Carolina. Growing up, I was instilled with a deep sense of connection and the desire to give back. My chosen path is driven by my desire and commitment to helping others and making a positive impact on my community. I'm enthralled by the profound influence that mindset can have on physical health, and I'm eager to explore how our thoughts and behaviors shape our overall well-being. Unraveling the mysteries of the mind and delving into the causes and motivations of our thoughts and behaviors is my passion. In my free time, I like to do photography and draw, capturing life moments that tell stories. Listening to music with my headphones on with a smoothie in my hand, while reading the latest John Grisham mystery, is my true, happy relaxation place. I certainly can't forget to include my fur babies--Vinnie and Bella! I love spending my down time with them, because I just find their presence and energies to be truly magical and comforting. I am super excited about the opportunity to work with y'all, and I'm really looking forward to meeting all of you!
