I'm so glad you're here.

I want to start by saying that if you’ve gotten this far and are perusing the websites of potential therapists, looking to start or resume the work of therapy, that you’ve already taken an amazingly difficult and important step. 

About Your Therapist

Katie Lenahan, LCPC, CADC (she/her)

About Me
Hi there! I'm Katie, and I'm a licensed clinical professional counselor (LCPC) and certified drug and alcohol counselor (CADC). My personal philosophy of therapy is this: none of us are broken, or need ‘fixing.’ We all have old ways of learning and coping that we developed along the way, through the twists and turns of life, that have helped us to survive our most difficult moments. However, there comes a time in which our life changes, or our environments change, or our relationships change; and our old ways of thinking or acting or learning or coping no longer serve us as they used to.


Our work together is twofold: first, we seek to understand and build compassion for our past learning and past experiences, while then examining our ways of coping and flexibly altering or adapting them as needed to fit our personal values, current environments, and to move towards the life that we want for ourselves.

Clinical Style
My personal style as a therapist and human is warm, direct, and transparent. I love to laugh and believe that humor is one of the most powerful mechanisms of healing that we have. I utilize a strengths-based approach and hope to pull from the reserves of courage, strength, and resilience that every human has inside of them. Though I use humor in my work and believe that it’s important not to take ourselves too seriously, I also balance this with the compassion and kindness that we all deserve when navigating a difficult moment or coming into contact with a painful experience.


I believe that there is nothing more important in therapy than the therapeutic relationship, and I feel honored and humbled every day by the trust that my clients have placed in me to support them in their courageous work. I strive to create a space where clients feel heard, seen, and accepted in relation to all parts of themselves; even the parts that, for years, may have been hidden or silenced by shame.

Clinical Experience
In my last role, I was the executive director of a group therapy practice, and led all clinical training and supervision related to eating disorders, body image concerns, and disorders of emotional overcontrol.

My clinical experience spans 15 years in all levels of care:

  • Community mental health settings

  • Residential treatment centers

  • Inpatient hospital programs

  • Partial hospitalization programs (PHP)

  • Intensive outpatient and outpatient settings

Clinical Training

I utilize and adapt empirically validated treatments such as:

  • Radically Open Dialectical Behavior Therapy (RO-DBT), training in which I received directly from the founder of this treatment, Dr. Thomas Lynch.

  • My experience includes over 130 hours of training in providing counseling and court advocacy services to survivors of domestic violence and sexual assault.

My Therapeutic Modalities

I have undergone extensive training in several therapeutic modalities which have a strong evidence and research base; and, my job is to support you in building a treatment plan that is best for you. I firmly believe that my clients know themselves best; and that people are not books!

Our struggles are unique to various aspects of our history, biology, identity, and upbringing. My job is to first learn about you, so that together we can build a treatment plan that is tailored to you and your needs.

Radically Open Dialectical Behavior Therapy (RO-DBT)

Radically Open Dialectical Behavior Therapy, or RO-DBT, is a therapeutic approach that emphasizes the value of openness, flexibility, and curiosity while celebrating playfulness, novelty, and rest. I am grateful to have received intensive training in RO-DBT from the founder of this treatment, Dr. Thomas Lynch. This approach is rooted in evidence-based research and has been shown to be effective in treating a variety of mental health conditions such as depression, eating disorders, and anxiety disorders. Together, we will build a life worth sharing!

Dialectical Behavior Therapy (DBT)

Dialectical Behavior Therapy, or DBT, is a type of therapy that combines elements of cognitive-behavioral therapy with mindfulness practices. DBT was designed to help individuals who struggle with intense emotions and relationships to build mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness skills. DBT has been shown to be effective in treating a variety of mental health issues, including borderline personality disorder, substance abuse disorders, and eating disorders. Together, we will build a life worth living!

Acceptance and Commitment Therapy (ACT)

Acceptance and Commitment Therapy, or ACT (pronounced like the verb 'act'), is a form of therapy that focuses on helping individuals develop psychological flexibility in order to live in accordance with their values. Through mindfulness and acceptance techniques, we can learn to embrace our thoughts and emotions rather than trying to control or eliminate them. This approach can be helpful for a variety of mental health concerns, including anxiety, depression, eating disorders, and chronic health concerns. Together, we will cultivate a values-oriented life!

Mindful Self Compassion (MSC)

Mindful self-compassion, or MSC, is the practice of being kind and understanding towards ourselves, especially during moments of stress or difficulty. I am grateful to have received intensive training in MSC by a leader in the field, Kristy Arbon. Self compassion involves being aware of our thoughts and feelings, and treating ourselves with the same warmth and care that we would offer to a friend or loved one; rather than responding with habitual shame or blame. Together, we will build a new response to pain; one of kindness and compassion.
