Aaron Silveus, RVT

I have been with Columbus State since 2012. As an adjunct instructor, I have taught in the Clinical Applications Courses, which are the hands-on portions of the student’s education. As with many Veterinary Technicians, the College has asked me to fill multiple roles while teaching. Some of which include teaching physical exams, anesthetic monitoring, male urinary catheter placement, and venipuncture.

I received my Bachelors of Science in Biology from the University of Findlay in 2009. I then began in the Veterinary Technology program at Columbus State Community College, graduating in 2011. Upon graduation I was hired at MedVet Columbus in the Neurology department. While at MedVet, I was also trained in the Oncology Department and would occasionally help in the Emergency and Critical Care Department. I joined the Banfield Pet Hospital of Polaris team in 2012. At Banfield, I was able to gain a vast amount of knowledge and refine my technical skills. Shortly after starting at Banfield, I was offered an Adjunct Faculty position at Columbus State. As of June 2015, I have joined The Ohio State University in the Small Animal Emergency and Critical Care Department. Emergency and Critical Care has always been an interest of mine and I hope that the experience gained in this department will aid me in educating Vet Tech Students.

In my free time I enjoy cooking, going to the movies, and socializing with my friends and family. I have two cats. Due to my busy schedule, I do not have a dog at this time, but would consider one in the future. I love interacting with the resident dogs and cats at CSCC and caring for my patients at OSU.
