About
Angelina MacLellan-Muise
Registered Psychologist, Founder & Director
(she/her)
With nearly a decade of clinical experience, Angelina MacLellan-Muise works with individuals (19+) and couples across Prince Edward Island, Nova Scotia, and New Brunswick. She offers support for a wide range of concerns, including anxiety, mood concerns, relationship difficulties, grief, stress and burnout, and challenging life transitions such as separation, family changes, and educational or career transitions. Angelina also provides psychological assessment services, including Adult ADHD assessments.
Angelina is passionate about creating a therapeutic space where people feel genuinely heard, understood, and accepted. She believes that therapy is most meaningful when it is collaborative and grounded in a strong relationship between therapist and client. Rather than approaching therapy with a one-size-fits-all model, she takes the time to understand each person's experiences, values, strengths, and goals. She views clients as the experts on their own lives and sees therapy as a process of working together to identify what may be getting in the way and what kinds of change would feel meaningful to them.
Her therapeutic approach draws from evidence-based frameworks including Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), and Emotionally Focused Therapy (EFT). She is trained in Emotionally Focused Therapy for Couples (EFT-C), supporting couples who are hoping to improve communication, rebuild trust, and strengthen their emotional connection. She has also completed training in Prolonged Exposure (PE) therapy for PTSD, an evidence-based approach for individuals experiencing trauma-related symptoms. Angelina integrates these approaches flexibly, selecting interventions based on each client's needs, preferences, and goals.
Angelina is a Registered Psychologist with the PEI Psychologists Registration Board based on her Master's degree in Counselling Psychology from the University of Western Ontario. She also holds a PhD in Interdisciplinary Studies (Psychology and Law) from Dalhousie University. After several years developing her clinical practice at a private practice in Halifax, Nova Scotia, she returned home to Prince Edward Island and founded Angelina MacLellan-Muise Psychological Services in 2024. She offers both in-person and secure virtual appointments.
Most importantly, Angelina is committed to continuing to learn and grow as a clinician. She believes there is always more to learn, both from ongoing education and from the people she works with. She values staying curious, keeping up with new research and approaches, and being open to feedback and reflection. For Angelina, being a good therapist means being willing to keep learning alongside her clients and continually finding ways to better support the people she works with.
