Hi, I’m Nicole. I have been in the optometry field since 2012 but am new to this office in 2017. I enjoy being a part of this business because I always find myself learning something new. My fav part of my job would be patient satisfaction. I believe in treating a patient the way I would like to be treated. Outside of the office, I like taking my daughter on mini adventures around San Antonio, just taking in the beauty around us.

Chad is the coolest member of the staff (in his own mind), joining our awesome team in March 2009. He has been in the optical field for 7 years and is an expert at optical sales and eyeglass styling and fitting. Lastly, Tampa Bay isn’t a real football team….Go Cowboys!! Like Dr. Nooshin, he also runs many half marathons (again-in his own mind)!
