Dr. Marshall has loved animals and working with animals since she was a child. When she was in high school she started learning anatomy and physiology and fell in love with it. She started exploring veterinary medicine as a career option to combine both passions and found it to be a great fit for her.

She worked at a small animal clinic for 8 years as a veterinary assistant through high school and her undergraduate degree. She briefly worked at an emergency clinic and an equine clinic before she settled in at Holistic Pet Care Center. She started working part-time at Holistic Pet Care Center when she was working on her bachelor's degree. She continued working part-time through veterinary school in the hopes of learning as much from Dr. Roach as possible.

She graduated from the University of Central Oklahoma with a bachelor's degree in Biomedical Sciences. She then started veterinary school at Oklahoma State University and graduated in May, 2024.
