“Three decades later and I am still in love with this work of therapy, supervision (we need to change that word!) and therapy training. The variety in it and the deep connections replenish me. The honour of being trusted with people’s hopes, fears, joys, and challenges remains humbling. Some people experience therapy as a lonely profession, but I have never found it so. It is relational and offers a network of peers if we go seeking that.”
— Niki D
Niki’s passion for her work stems from a personal and professional commitment to supporting people in open and polyamorous relationships, as well as people across the spectrum of gender and sexual diversity. She values the dynamic and unpredictable nature of her work, always learning and growing alongside her clients.
