Meet the faces behind Psyched to Move!

Founder, CEO
Hsingfang Chang
Dr. Chang is a licensed psychologist practicing in Pasadena, California.
Originally from Taiwan, she got a masters degree in Educational Psychology from University of Minnesota, Twin Cities, then a doctorate degree in Counseling Psychology from the University of Southern California. Her experiences as an international student and a new immigrant have shaped her to respectful of diversity, and informed her to be culturally sensitive in her clinical practice as well as in her interactions with others. She also understands what it means to be a member of minority group and she makes efforts to help people feel seen and heard.
In her spare time, she enjoys challenging herself in trying new things, such as taking flamenco dance lessons, taiko lessons, Zumba lessons, and participating in 5K and 10k events.
Because Dr Chang knows and experienced the benefits of exercise on mental health, she wants to encourage more people to join her together to “exercise the body, exercise the mind”!

COO
Sarah Irene Muller
Hi! My name is Sarah Muller. I am a junior at Scripps College majoring in Psychology and Linguistics. I love the outdoors, and take whatever chances I get to go hiking, camping, beaching, or simply lay out in the sun. I began running 5Ks with my Mom and my godfather when I was 10 years old, and now continue that tradition with my friends as well. I find that above all, any form of exercise is a way for me to connect with the people I love and I can't wait to continue sharing that through Psyched to Move! In my free time, you can find me exploring outside, thrifting, ballroom dancing, or trying my hardest to keep my plants alive.

Marketing Director, Chief Technology Officer
Julie Chen
Hi! My name is Julie Chen, and I am a senior at Scripps College, majoring in Psychology and minor and Data Science. I personally believe that exercise can be scary, but when I am running, I feel in control of my body and thoughts, allowing me to truly enjoy exercising while giving myself a break from work and stress. I hope that my passion and motive for running can inspire others to feel more comfortable in their own body and to enable them to take control of their own lives through something as simple as running.

Legal Consultant
Rachel Lin
Hello! I am a litigation attorney in Los Angeles and a NASM Certified Nutrition Coach. I'm passionate about advocating for workers' rights and supporting people in improving their health and well-being. I bring to Psyched to Move my experience counseling individuals through high-stress workplace or business disputes, as well as my commitment to accessible movement and self-care. Outside of my legal practice, I enjoy strength training and keep up a regular running habit by training for races, particularly those that come with a finisher's medal. I recently completed the Rose Bowl Half Marathon in 2026.

Chief Creative Officer
Annie Koo
Hello! My name is Annie Koo, and I am a student at ArtCenter College of Design, majoring in Illustration. While exercising isn’t always my top priority, I know how important it is to make time for it. I personally play badminton as a way to take a break from art projects, which often leave me glued to my desk for hours on end. I’m excited to bring my design skills to Psyched to Move and I hope that at the same time, this experience will serve as a reminder to step outside, connect, and keep moving.
