My Ideal Client

My ideal client is someone who is struggling to understand and move forward in their life and is ready to work hard and become open to new ways of looking at things.

My Approach to Helping

I specialize in providing comprehensive neuropsychological evaluations, cognitive rehabilitation, and evidence-based therapy for trauma and anxiety. In providing evaluations, I will tailor my approach to be both relevant and validating. In therapy and rehabilitation, I provide a safe and accepting therapeutic environment, where we will explore your needs and goals and decide together on a treatment plan. Brain science shows us that our minds have a profound capacity for healing, especially when tapped into correctly. I focus on providing you the treatments that are scientifically supported, and that work relatively quickly. I use evidence-based treatments to help my clients realize the life they envision for themselves. Unlike some traditional therapy, evidence-based therapy draws upon cutting edge research to harness your brain's neuroplasticity and create profound, positive changes in your life over a relatively short period of time.

My Personal Beliefs and Interests

I emphasize the human connection in assessment, rehabilitation, and psychotherapy with my clients. Due to my unique specialization in treating survivors of complex physical and psychological traumas, I am especially drawn to helping people who have complicated or co-existing mental and physical health conditions, especially those who have had limited success with psychotherapy in the past. I take a holistic and pragmatic approach to therapy while calling upon the latest research in mental health and neuroscience. I earned both my Masters and Ph.D. in Clinical Psychology from American University in Washington, D.C. I completed my predoctoral internship and postdoctoral fellowship through Veterans Affairs (VA) Hospitals, where I specialized in neuropsychological assessment and treatment of Veterans with PTSD, Traumatic Brain Injury, and other complex physical and mental health conditions. I am board certified in clinical neuropsychology (ABPP).

Techniques I Use


  • Psychological Testing and Evaluation  External link

    I am a board certified neuropsychologist, which means I have the highest qualification in providing clinical neuropsychological evaluations for adults. I specialize in dementia, TBI, and movement disorders, such as Parkinson's Disease.

  • Acceptance and Commitment Therapy (ACT) External link

    Acceptance and Commitment Therapy, or ACT, focuses on changing our relationship to our thoughts and feelings. With ACT, I will teach you how to generate more present moment awareness, get unglued from obsessive or depressive thoughts, and engage more in value-driven activities. ACT is very successful in treating depression, anxiety, chronic pain, obsessive-compulsive disorder, and psychosis.

  • Emotionally Focused External link

    Emotion-Focused therapy, or EFT, can help you identify, utilize, and process emotions. Suffering comes when we encounter distressing emotions but try to resist or avoid them rather than accept and feel them fully. With EFT, I help patients learn to recognize their emotions and feel them in a safe and validating way.

  • Cognitive Behavioral (CBT) External link

    Thoughts, feelings and behaviors are inter-related, so altering one can help alleviate problems in another. Cognitive behavioral therapy aims to help you identify, challenge, and modify unhelpful ideas or behavioral patterns. CBT also includes relaxation training and guidance for interpersonal relationships. I use CBT to help clients suffering from phobias, anxiety, panic, or depression.

Issues I Treat


  • PTSD External link

    Posttraumatic Stress Disorder (PTSD) can occur as a result of a physical, sexual, psychological or emotional assault, or threat. It can rock you to your core, causing you to rethink everything you once knew. But symptoms of PTSD are very treatable. I use Cognitive Processing Therapy, Prolonged Exposure, Adaptive Disclosure, and mindfulness strategies to help you move forward in your life.

  • Alzheimers External link

    I am a board certified neuropsychologist who specializes in working with older adults. I offer comprehensive neuropsychological testing to assess for changes in thinking. I help individuals understand these changes in a way to provide clarity, understanding, and tools/strategies to move forward and plan for the future.

  • OCD External link

    You may feel trapped by nagging and intrusive thoughts that you feel have no “off-button.” Or, you may feel compelled to engage in certain behaviors to a point where they impede on your quality of life. Have hope. Obsessive thinking and behaviors are very treatable. I help my clients understand their symptoms and unlock the door to an easier, more comfortable way of existing.

  • Anxiety External link

    Anxiety, panic, and phobias can be suffocating. You may feel tense, preoccupied with worry, or experience an elevated heart rate, upset stomach, chronic pain, or headaches. These issues arise when our nervous system goes on overdrive and our body doesn’t distinguish between actual threats and imagined threats. I use evidence-based practices to help you break free from the control of anxiety.

  • ADHD External link

    I provide comprehensive evaluations and cognitive rehabilitation to help individuals cope and manage ADHD. I don't just work to help people compensate for ADHD but also harness the "superpower" that ADHD can also afford.
