This concise guide applies the principles of Existential-Humanistic therapy to the practice of clinical supervision. With the skillful use of case examples—including transcripts and analyses of real sessions with a real clinical trainee—the authors utilize the key ingredients of the E-H therapeutic approach, including empathy, acceptance, and genuineness, to model how trainees can create safe, collaborative, and supportive relationships with clients. E-H supervisors help trainees learn to enter their clients' self-constructed worlds, using their own personal contexts to develop responsiveness to clients, while also cultivating the "presence" that enables genuine encounters and real therapeutic change.
