Sina Holzerland, M.Sc., is a clinical psychologist and holistic coach who blends science and spirituality through sound and hypnotherapy. Her CrystalTones® sound bowls, tuned to 432, 440, or 528 Hz, activate deep relaxation, balance the nervous system, and stimulate natural healing at the cellular level. Combined with hypnotherapeutic techniques, they facilitate mental clarity, emotional resilience, and profound inner calm. With experience teaching in Hamburg, Schleswig-Holstein, and Bali, Sina offers private sessions, workshops, and corporate events, guiding clients to reconnect with their inner resources, awaken intuition, and embody intentional, balanced living. A transformative journey for mind, body, and soul.
