Donna Cotzen, MD

Donna CotzenThere are many things I have come to love about Gestalt Therapy. First, the clarity and simplicity of the theory is elegant. Second, it takes the truth that I have learned from psychoanalysis and makes it deeper and three dimensional. I can see the theory in action instead of forcing understanding with my left brain ,which was not really understanding with my whole self. And lastly, it gives me a personal philosophy and guide of how to live my life that leads to engagement and happiness while bringing me into a community of therapists who are fun, warm, intelligent and interested in their own personal growth as well as the growth of their clients. I am stimulated by the people I meet here who are open to new experience, willing to be vulnerable and courageous enough to explore the unknown.

Donna Cotzen is a psychiatrist in Center City Philadelphia. She attended college at Boston and Temple Universities, received her medical degree from Women's Medical College in Philadelphia, and her residency in psychiatry at The Institute of the Pennsylvania Hospital. She completed her Gestalt Therapy training at The Pennsylvania Gestalt Center. She is adjunct faculty at Jefferson Medical College and The University of Pennsylvania, where she supervises residents in individual and group therapy. Her practice focuses on individuals and families, doing both psychotherapy and psychopharmacology and she has a special interest in dealing with the problems of single people.

Cathy Gray, MSS, LCSW, BCD

cathygray optWhen I first took a formal class in Gestalt Therapy at BMC, I felt as if I had come home. It was and still is exciting to me to to be practicing a theoretical model that defines health as being able to be present and aware, choiceful, resilient, passionate and effective in one's life. This is a a theory and approach that not only makes sense to me, but also fits my values and way of looking at the world. Rather than pathologizing and labeling people, Gestalt Therapy respects their ability to creatively adjust to circumstances in their earlier lives in which they had few viable choices. It also recognizes that when those same adjustments are brought into current day situations they may no longer be useful. Gestalt therapy recognizes that we hold the shadows of our past not only in cognitive structures but also in our body. As a Gestalt therapist I work holistically, hightening awareness of both physical manifestations in the body, as well as cognitive structures and behavior habits that interfere with the individual being fully present and effective in their life. I have a private practice working with individuals, couples, and groups. I also offer embodied supervision to psychotherapists.

Cathy has more than 35 years working with individuals and organizations. She trained at the Gestalt Therapy Institute of Philadelphia. Cathy also studied, Focusing, Mind Body Centering, Improvisational Movement, in addition to Developmental Somatic Psychology with Ruella Frank. Cathy is on the faculty and board of GTIP and is past president of the Association for the Advancement of Gestalt Therapy.

Mark Magerman, PhD, LCSW, BCD

Mark MagermanAt each moment we are in process of evolving from who we have been to who we are becoming. We often hold firmly to our past due to stories of experiences that we hold...and create about the future, causing us to compromise our personal, professional, and relational power.
I view Gestalt Therapy as a philosophy for living and a living philosophy. Whether engaged in relationships with individuals, families, groups, or organizations, it is a conscious and deliberate use of ourselves that invite opportunities for others to complete what is unfinished from the past and give way to their creative, energetic, and meaningful lives.


Mark is a licensed/board certified clinical social worker. For over 34 years he has worked with individuals, couples, families, groups, and organizations as a psychotherapist, educator, coach and consultant.

Ginny McIntosh, MSW, LCSW, BCD

Ginny McIntoshWhen I did my graduate studies at the Penn functional School of Social Work, I was trained in the "here and now," "growth through pain," human justice and acceptance of the individual as she or he is within her or his context. After my journeys far away from this through systems family therapy, psychodrama, object relations psychotherapy, and self-psychology, imagine my surprise to discover how closely Gestalt Theory fits my graduate training — now I'm back at home to stay within the Gestalt Therapy theory, philosophy and community when I graduated from GTIP in 1988. It has validated my identity as a clinical social worker and enlivened my sense of self; personally and professionally ever since. It has never failed me nor my need to grow and I also notice that is true in my work with people as well, whether it be in therapy, teaching or supervision. I feel honored to be part of the Gestalt community and excited by the teaching, clinical work, and witness to other people's growth.

Ginny McIntosh has worked in protective services, ten years in mental hospitals and twenty-five in private practice with individuals, couples and supervision. She has taught at St. Joseph's University, Widener University and for many years at Bryn Mawr Graduate School of Social Work and Social Research. She has also co-led Gestalt Therapy training groups for therapists for several years.

Cindy Orns, MSS

I came to Gestalt Therapy after practicing as a psychodynamically trained therapist for fifteen years. Gestalt Therapy Theory spoke to me personally and professionally. It's emphasis is on relationship and making contact with the other. It is concerned with helping people figure out what they want and how to get it. Also it allows the therapist to be actively engaged in the process with the client. Finally the social action component is focused on equality, democracy and valuing each persons voice.

Cindy Orns MSS is a licensed clinical social worker. She attended University of Vermont, Boston University and Bryn Mawr Graduate School of Social Work. Cindy has worked in inpatient settings, outpatient mental health agencies and private practice. She currently maintains a private practice in Chestnut Hill, Pennsylvania and sees individuals and couples. Cindy also supervises clinicians interested in Gestalt Therapy.

Adjunct Faculty

Debra Brosan, MA, OD, ACC

Debra Brosan As an Organizational Development Consultant, my work over the past several years has led me to the Theory of Gestalt Therapy and its' humanistic interventions and strategies to enhance meaningfulness in work. I have integrated the Theory of Gestalt Therapy in working with leadership, teams and individuals as a coach and consultant. Meaningful work is (and is not limited to) acknowledging and buying into the purpose of the organization, alignment of organizational and individual visions, clarity of values and beliefs that mobilize oneself within the organization and job satisfaction. The vehicle and process that I use for achieving this is by helping my clients identify how they see themselves in their systems, as well as the systems-as-a-whole. 

Debra has extensive experience in organizations in various roles, including president of a packaging company at 30 years old, where her leadership in operations and strategic management were essential to the company's success. For the past decade, she has applied her business experience to strategic planning and organizational development in all types of organizations. She focuses on themes of communication, planning and transition that arise from the rapid and often humanly-impossible-to-keep-pace-with shifts in the world of work.She has extensive experience in strategic planning, organization development, coaching and training with expertise in leadership, personal impact and teaming.She founded gestaltworks, llc and consults with a wide range of organizations, from non-profits and faith-based to large organizations and flourishes on the variety and difference they offer.

Karen Ginsburg, LCSW, LMT

k ginsbergI am a deeply kinesthetic person. I learn first through movement and felt sensation. Early in my life, this orientation led me first to performing and then to bodywork. Despite moments of satisfaction as a performer and bodyworker, I felt I was missing a bridge between movement and sensation and my and my client's psychic selves. In Gestalt therapy I found the perfect explication of the holistic nature of existence and how how to combine my interest in presence and embodiment with the psychological structure of myself and others. Gestalt theory described perfectly how I saw the world, and left me the freedom to follow both the words that are spoken, and the sounds and movements that run underneath them. In this way, doing therapy is much the same as doing an improvisational dance, my clients and I are thinking, moving and feeling together, creating something new in each moment, and I feel right at home. Gestalt therapy has taught me to trust in the present moment. There is always another breath after this one. I have learned to have faith in what will emerge when I sit with another person and we both bring our awareness to the present moment as we concomitantly think, feel and sense it. In these moments, something magical happens. We are who we know ourselves to be, and we are at the crossroads to become more than we just were. We find support in ourselves and in other people, and we find an intelligence and liveliness that underlies even our deepest struggles. I feel ridiculously lucky to have found this philosophy and practice, and am grateful to the founders of Gestalt therapy, and its continuing teachers and theoreticians for creating this useful, enduring, and elegant structure for living and for change.

Janneke van Beusekom, PhD, MSS, LCSW

 Janneke van BeusekomIn my years studying and practicing Gestalt therapy I've discovered that people come to Gestalt through many different avenues. Though I didn't know it at the time, my interest in Gestalt therapy began when I was in college and was introduced to existentialism, epistemology, and Martin Buber's "I-thou." It wasn't until almost 10 years later that I discovered that these ideas didn't just live in my head; they could inform my being and my relating, not just my thinking. For me, it is this wonderful combination of fullness of being (emotional and embodied) and mutuality in relationship – all based on a grounded, informed way of thinking – that continues to bring me to Gestalt therapy over and over. My intention as a faculty member of the Gestalt Therapy Institute of Philadelphia is to support others and me, gently and compassionately, while we create and discover our fullness through thinking and feeling, being and relating.
