Isaac Nathan
Clinical Psychologist
BSc (Hons) MPsych (Clinical) MAPS MACPA
Practice Locations: VIC - Caulfield, Collingwood
Isaac is a clinical psychologist who provides individual and group therapy for adults. He has worked in private practice for 10 years, also serving as senior clinician in his public mental health and private hospital roles.
Isaac sees patients with a range of clinical issues, including mood disturbances (depression, rumination) anxiety (generalised anxiety, worry, panic) and more entrenched problems arising from trauma (post-traumatic stress disorder, anger, attachment issues), and obsessive-compulsive disorder (OCD).
Isaac takes aactive and collaborative approach to therapy, in which he works together with you to define a project to address the core concerns. He aims to make the most of each session, finding the path to create significant changes to how you live your life and how you relate to those around you. Such changes can be hard work, but the rewards can be enormous. And although therapy can be challenging, the struggle is often balanced with experiences of joy, inspiration, and humour.
Isaac is trained in several evidenced-based therapies: Cognitive Behaviour Therapy (CBT), Acceptance & Commitment Thearpy (ACT), Prolonged Exposure (trauma therapy), and Psychodynamic therapy. He provides supervision to psychologists and can be contacted here.
Isaac’s work is influenced by existential psychologists - Rollo May, Irving Yalom, Nancy McWilliams and others. This view is sensitive to issues of existence that we face along the lifespan: how to navigate important life transitions (loss, breakup), sense of stuckness in one's circumstances and relational patterns, attachment issues, persistent loneliness or isolation, disconnection from work and sense of vitality, or uncertainty about how to discover a sense of meaning and personal growth through a difficult life experience.
