Mackenzie Cummings


Doctoral Student
Mental Health Counselor Associate

Mackenzie believes in the collaborative nature of therapy, viewing it as a partnership between client and therapist. Her primary goal is to help you discover the innate strengths you already possess, empowering you to confront your concerns and overcome life's challenges and transitions. Through this process, she aims to facilitate your healing and foster personal growth, guiding you towards a life that aligns with your core values.

Mackenzie specializes in assisting individuals who grapple with interpersonal difficulties, trauma, and anxiety. She utilizes evidence-based treatments such as cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT), but she ulimately tailors her approach to your specific needs, drawing from a diverse range of therapeutic techniques.

In her work with couples, Mackenzie integrates psychodynamic insights with Gottman Method Couples Therapy. She aims to empower couples to communicate effectively, forge deeper connections, and break free from destructive relationship patterns. Recognizing the vital role that healthy intimacy plays in relationships, Mackenzie guides couples towards achieving closer connection.
