Aaron Sterba, Ph.D.

As a member of Greenepsych’s team, and as a licensed psychologist, Dr. Sterba provides both clinical and sport psychology support to clients. For much of the last decade, Dr. Sterba has worked at an NCAA Division I program, where he has provided the clinical, peak performance, and leadership development services offered to student-athletes, coaches, and administrators. Dr. Sterba has a first-hand knowledge of what it takes to perform in high pressure environments, and is passionate about teaching mental skills to individuals, teams, and groups.

In addition to his extensive collegiate experience, Dr. Sterba has worked with individuals and teams at the professional, Olympic, elite high school, and recreational levels. Athletes and other performers seek out Dr. Sterba for both his ability to understand the challenges of performing under pressure as well as his advice on how to take one’s performance to the next level.

Dr. Sterba also has over a decade’s worth of experience working with students in several university counseling centers. Dr. Sterba brings a personable, engaging, and real world approach to his therapy work, which is relational and strengths based. His therapeutic approach integrates interpersonal, psychodynamic, cognitive behavioral, and mindfulness techniques.

Dr. Sterba received his undergraduate degree in psychology from the University of Delaware, completed a Master’s degree in Clinical Psychology from West Chester University of Pennsylvania, and earned his Ph.D. in Counseling Psychology from the University of Memphis. He completed his doctoral internship training at the University of New Hampshire Counseling Center. Since completing his internship at UNH in 2007, Dr. Sterba has been employed at Lehigh University’s Counseling Center, where he currently serves as the Clinical Director. In addition to providing therapy (group, couples, and individual), training, and supervision within the counseling center, Dr. Sterba plays an integral role in the greater university system and the Division of Student Affairs. Within the university, he is a leader in addressing, managing, advising and consulting with faculty, staff, parents, students, and administrators regarding the mental health needs of the campus community.

Dr. Sterba makes his home in Bryn Mawr PA, where he is married with two children. Personally, he has always been immersed in the world of athletics, competing in many different sports. During high school he was a four year varsity tennis and ice hockey player (where he was a team captain and an Eastern PA 1st team all-star). He continued on as a four year varsity collegiate ice hockey player, and you can occasionally still find him out in one of the local men’s leagues. Dr. Sterba has maintained a recreational interest in a number of sports and is always looking to sneak out on the golf course for a quick 9 or 18. However, these days you will more commonly catch him out at one of the youth athletic venues nearby, where he takes the role of a devoted and supportive fan. One of his greatest joys in life is cheering on his children, as they are both active participants.

To make an appointment or to simply hear more about the types of clinical and sport psychology services Dr. Sterba can provide, please email him at or by phone at 484-380-5520.

Nina Rizzo

Nina has joined Greenepsych as a counselor and mindfulness coach. As a lifelong athlete and NCAA competitor, Nina first came to mindful practices after suffering a career-ending injury during her freshman year of college. It was during this difficult transition that she found the practices of yoga and meditation could help heal her mind, body and spirit.

Nina’s own experiences have armed her with tools to inspire others to live their most optimal lives. Nina’s focus at Greenepsych is to help guide athletes and non-athletes towards a more fulfilling lifestyle of present moment awareness, balance, and empowerment. She does this through teaching mindfulness meditation, in both one-on-one and group settings.

Nina has served as a mental skills coach for athletes on Haverford College’s Field Hockey team and speaks regularly to a number of local cross country and track teams on present focus awareness and quieting the mind.

Nina is currently working toward her LPC as she pursues her Masters degree in Clinical Counseling Psychology at La Salle University. She currently holds a Bachelor of Arts in Psychology from Widener University, is a 200 Hour Registered Yoga Teacher, Certified Meditation Teacher, Certified in Mindfulness Based Stress Reduction, and has completed Master Class Levels I & II with NY Bestselling Author, Gabrielle Bernstein.
