Teaching Interests

Teaching Philosophy
"I believe students are motivated by different factors. This is constantly changing as our environment and society changes. In order to inspire students and be most effective, I believe these factors need to be identified and incorporated into the classroom setting."  

"In addition to providing the students with the educational foundation they need to succeed, I hope to instill in them the importance of empathy in any health care profession. In my opinion, it is the most important characteristic to have as a health care provider. If you have empathy, it will lead you to properly prepare to provide the absolute best care for your patients."
