Elizabeth Clark
PRESIDENT
emc2305@tc.columbia.eduElizabeth Clark is a second-year, full-time M.A. student in the Social-Organizational Psychology program at Teachers College, Columbia University. As OHDCC President, she is excited to work with the Leadership Board and club membership to create events, activities, and resources that support students’ career development, strengthen community connections, and enhance the student experience at TC.
Before starting at Teachers College, Elizabeth worked for 15 years in strategic nonprofit communications, most of that time on the health care and sex education media team at Planned Parenthood Federation of America. She has a decade of experience in team leadership and project management, and a passion for using evidence-based tools to make workplaces and team spaces more inclusive, more collaborative, and more human. Her best professional days are when she can be immediately helpful to others: brainstorming with colleagues, problem-solving and improving processes, creating and sharing tools, designing and leading trainings, or planning and facilitating team retreats. She is deeply committed to diversity and inclusion, and as a team manager of more than a dozen diverse staff over six years, continually sought tools to help foster a team culture where all members felt valued and engaged. One of her favorite pieces of staff feedback called her "an amazing, caring, + fearless leader."
Elizabeth has also worked as a productivity consultant at Double Gemini, designing and enhancing processes and tools for better workflows and enhanced collaboration, and co-creating an in-house model of change management. After graduation from Teachers College, her goal is to continue helping teams and organizations transform their workplaces into sources of joy, connection, and innovation for good.
Elizabeth earned her first M.A. from the Communications, Culture, and Technology program at Georgetown University. She is also the co-founder, with her two sisters, of Trivium College Advising, a firm supporting high school students and their families navigate the college admissions process with confidence and excitement. Outside of school and work, she loves spending time with friends and family, eating foods of the world, a good dance party, horror movies and pop culture gossip, and road trips of any length. She’s a dog person without a dog, and will always choose pie over cake unless coconut or banana is involved.

Jaime Ballesteros
VICE PRESIDENT
jb5016@tc.columbia.eduJaime Ballesteros is a third-year, part-time student in the Social-Organizational Psychology M.A. program at Teachers College, Columbia University. As Vice President of OHDCC, Jaime is excited to contribute to the S-OP community and help create opportunities for students to connect, learn from one another, and get more out of their time in the program.
Jaime brings more than a decade of experience across Human Resources and education. His work has given him the opportunity to see how different parts of the employee experience contribute to building strong, high-performing teams. He currently works in Employee Relations at a global financial technology firm, where he coaches leaders through complex people and performance challenges and helps strengthen their teams. Previously, he held roles in diversity and inclusion, recruiting, and talent programs across financial services and technology.
Jaime began his career as an 11th-grade Chemistry teacher in South Los Angeles through Teach For America. During his time in education, he also served as a department head and member of his school’s instructional leadership team, where he helped lead professional development for fellow teachers. His work in the classroom and throughout HR ultimately shaped his interest in how people experience work and organizations and led him to pursue graduate study in Social-Organizational Psychology.
Jaime holds a Master’s in Urban Education Policy from Loyola Marymount University, a professional certificate in Human Capital Management from New York University, and the SHRM-SCP certification. Through the S-OP program, he has enjoyed exploring new perspectives on leadership, teams, and organizations while connecting them to his professional work.
Outside of work and school, Jaime enjoys running and workout classes, taking his dog Manila to sniff every tree in Brooklyn, and continuing his search for the best Filipino food in NYC.

Christin Enke
DIRECTOR OF PROFESSIONAL DEVELOPMENT & ALUMNI AFFAIRS
ce2554@tc.columbia.eduChristin Enke is an M.A. student in the Social-Organizational Psychology program at Teachers College, Columbia University. As OHDCC's Director of Professional Development and Alumni Affairs, she is excited to build meaningful connections between students, alumni and employers through networking events, employer exclusives and the club's signature case competition.
Before coming to Teachers College, Christin spent six years leading organizational change across manufacturing, healthcare, and government sectors in Europe, most recently as a Strategy & Transformation Manager at an 80-year-old family-owned business, where she trained more than 250 managers through digital change. That experience of building trust and coaching leaders is exactly what she hopes to bring to OHDCC's professional development programming. Her interest in bringing people together goes back further still: during her bachelor's degree, she served as Head of People & Culture for the Student Business Consulting Club in Berlin, matching skills among members and alumni to build something new together. Christin is known for her drive to achieve results as a team, her genuine way of building trust, and her ability to allocate resources where they're needed most, and she is looking forward to bringing these strengths to OHDCC.
That same instinct connecting people to build something meaningful together is what drew Christin to OHDCC. She is passionate about change and in particular about closing the gap between complex technology and human behavior: the best strategies and tools only matter if people trust them and feel part of the process. She sees OHDCC as a place to put that passion into practice, helping fellow students build the relationships, skills and community that make change and career transitions feel a little less daunting.
Christin earned her M.Sc. in Organizational Development from Leopold-Franzens University Innsbruck and Stockholm Business School, and her B.Sc. in Business Administration from Humboldt University Berlin. She is a certified Professional Scrum Master and Systemic-Integrative Coach. Outside of class, running is a real passion of hers. She loves heading out without music, just to be in her own flow and reset. She is also very much a family person, having grown up with five siblings, including her twin sister; those family dinners sparked her love of plant-based cooking, which she still enjoys whenever she has time.
