5/5
I believe Dr. Klatt is the best in the world at what she does. I know this doctor knows the VA was created to serve those who wore the uniform. She works with veterans and truly cares about what she does. She has always showed all the values the Department of Veterans Affairs stands for Integrity, Commitment, Advocacy, Respect, and Excellence. Dr. Klatt is a one in a million find.
