Dr. Corynn (Cory) Tomlinson, Psy.D, CADC

Short Biography

About Cory

Dr. Corynn (Cory) Tomlinson is a Post-Doctoral Clinical Psychology Fellow whose practice is grounded in the most current evidence-based psychological science. She specializes in complex dual diagnoses, supporting individuals who are navigating the often-interconnected challenges of mental health and substance use. Cory’s therapeutic style is collaborative and holistic, built on the belief that real healing happens not through advice-giving, but through genuine partnership. She creates a safe, nonjudgmental space where clients are recognized as the experts on their own lives, and where movement toward an authentic, values-driven life is always the goal.

Education & Training

Cory holds a Doctor of Psychology (PsyD), reflecting doctoral-level training in clinical psychological assessment and evidence-based treatment. She is also a Certified Alcohol and Drug Counselor (CADC), a specialized credential that equips her to address the full complexity of co-occurring mental health and substance use disorders. She currently practices under the clinical supervision of licensed psychologist Dr. Liara Montesano.

Clinical Specialties

  • Dual Diagnosis and Co-Occurring Disorders – Providing integrated care for clients managing both mental health conditions and substance use challenges simultaneously.
  • Substance Use and Recovery – Drawing on CADC training to support individuals at any stage of the recovery journey with compassion and clinical depth.
  • Mental Health Treatment – Addressing a broad range of psychological concerns using the most current, research-supported approaches available.
  • Couples Therapy – Supporting partners in building healthier communication, emotional connection, and shared resilience.
  • Family Therapy – Helping family systems navigate conflict, change, and the relational dynamics that affect everyone within them.

Treatment Approach

  • Acceptance and Commitment Therapy (ACT) – A Third-Wave CBT approach that helps clients clarify personal values and commit to meaningful action, even in the presence of difficult thoughts and feelings.
  • Motivational Interviewing (MI) – A collaborative, client-centered method that strengthens a person’s own motivation and readiness for change.
  • Relational Therapy – Centers the therapeutic relationship itself as a key vehicle for healing, with particular attention to how connection, trust, and attunement support growth.
  • Third-Wave Cognitive Behavioral Therapy (CBT) – Integrates traditional cognitive-behavioral strategies with mindfulness, acceptance, and values-based approaches for a more holistic therapeutic experience.

Who They Serve

Cory works with individuals, couples, and families seeking support for mental health concerns, substance use and recovery, and co-occurring conditions. She is especially well-suited for clients whose challenges exist at the intersection of emotional well-being and addiction, a population that often benefits from a provider with both psychological and substance use credentials. Her collaborative, non-pathologizing approach makes her a strong fit for clients who have felt misunderstood or unseen in previous care settings.

Professional Experience

Cory is currently completing her post-doctoral fellowship under the clinical supervision of licensed psychologist Dr. Liara Montesano. In this role, she provides teletherapy services to individuals, couples, and families, bringing doctoral-level training together with her background as a Certified Alcohol and Drug Counselor. Her dual-credentialed foundation allows her to offer a level of integration between mental health and substance use care that is relatively rare in outpatient settings.

Personal Touch

Cory is drawn to the work of meeting people at the most complex crossroads of their lives, where mental health and recovery converge and where the stakes feel highest. What makes her approach distinctive is the combination of rigorous, up-to-date clinical training and a genuinely human presence that refuses to reduce clients to symptoms or diagnoses. She views the therapy relationship as a partnership, and her role within it as a fellow traveler rather than an authority. Her commitment is to help each client move toward the most authentic version of themselves, whatever that path looks like.
