"I have known Marilyn for six years, first as a graduate student, and then supervising some of her work as a practising clinician. She is a very reliable therapist who brings great personal presence and compassion to those with whom she works. She demonstrates tireless interest, advocacy, integrity and professionalism in her work and does not shy away from complex client situations. She will stay with you through the hard parts. I trust her work."

"Intuitive, knowledgeable and informative. Marilyn is an effective counsellor, and has helped individuals and couples from matters ranging from communication, mood, to trauma."


"My partner and I saw Marilyn Sundeen for couples counselling.  Marilyn was very knowledgeable, professional and provided a safe place for our work.  Her explanations of Attachment Theory were particularly helpful.  We always felt heard and understood."
