Career goal: To establish a reputation of being an effective, compassionate, and well-trained mental health professional and couples counselor in North Texas.
Coolest travel adventure: In 2010, I spent two months traveling and competing against some of the professional softball teams in China. I loved the experience of trying new foods, connecting with Chinese athletes, and being forced to adjust to various aspects of Chinese culture (like eating every meal with chopsticks and going to most places on foot rather than by car).
Greatest achievement: Competing in the Women’s College World Series with my 2011 Oklahoma State softball team.
Passions (other than therapy): Staying active (running, lifting weights, spending time outside), grilling out with friends and family, watching sports on the patio, teaching/training youth softball players, and reading research (particularly in the field of mental health or medical advancement).
