Personal Note

In my career, I have learned to be patient, to step aside and learn, and exchange knowledge. I've discovered that in order to get where you want to be, you need to work very hard and be positive.

In my spare time, I enjoy spending time with my family and my pets. I am a huge animal lover and at one point my family had 3 dogs and 3 cats. One of my biggest passions is traveling. I try to travel as much as I can and learn about different cultures and languages. My travels have taken me to many places around the world including two of my favorites which are Croatia and Greece. I am fluent in speaking Farsi, even though I have never been to Iran. I definitely plan on visiting that country one day. I also still enjoy my childhood passion for dance and music.
