Lori Summers, RP(Qualifying)

Formerly a student clinician at NSTN, Lori Summers now practices as a Registered Psychotherapist (Qualifying) and embraces the clinic’s inclusive approach to serve the needs of the community. Lori offers both individual and couples therapy, which she approaches with a professional yet gentle view. She recognizes that most people don’t anticipate that they may one day lose sight of their strengths, or become stuck, or feel lost and out of control—in spite of the fact that all this is common and very human. Having shifted into the psychotherapy field mid-career, Lori’s life experiences and their inherent struggles bring insight and compassion to her therapy.

Lori has worked with clients who are experiencing mild to moderate mental health symptoms as well as those clients who are experiencing disorders such as: generalized anxiety, post-traumatic stress, major depressive, bipolar, schizoaffective, and borderline personality. Her integrative approach includes common factors that cross many therapies including, empathy, non-judgment, incorporating a positive regard for each person no matter the circumstances, inspiring hope, assisting with alternate views of the self and world, and creating experiences directed at improved emotion. Lori welcomes the client’s active voice in session as they work on goals and an individualized treatment plan. She draws from one or many evidence-based therapies (CBT, DBT, SFT, Emotionally Focused Therapy, and others), depending on the need.


NSTN Student Clinic

The clinic attracts students who are completing the practicum portion of their academic studies. They are supervised by Sarah Durant while they accrue hours of experience and contribute to NSTN and the community by seeing clients at a reduced rate. See our Services tab for information on our current students.


Our Supportive Staff

New clients are often introduced to NSTN through Emilie or Marie who answer their initial inquiries. Their friendly and professional interactions provide a warm introduction and support much of the behind-the-scenes work at NSTN.


Our Extended Network

We also have a robust referral system that extends into a community of caregivers that we have built strong connections with over the years.
