I value the importance of creating a safe, supportive and collaborative environment to help facilitate personal growth and healing from the overwhelming challenges we sometimes face in life. Pain is part of our human experience. However, suffering does not have to be. My focus is to provide my clients with practical and effective interventions that are tailored to their specific needs. My clinical practice is highly informed by principles of neuroscience, interpersonal neurobiology and evidenced based psychological interventions. My aim is to assist, encourage and empower my clients on their path forward in reaching their goals.
My areas of clinical experience and expertise in psychotherapy include treating mood and anxiety disorders, grief and bereavement, trauma-related disorders. I also see clients for a variety of other issues, including; adjustment to difficult life events, explosive anger issues and life transitions.
Engaging in psychotherapy is often a courageous decision. I will work with you to tailor a therapy that is sensitive to your needs. I have worked with individuals over the years to witness dramatic improvements. I appreciate the opportunity to partner with you in realizing that change in your life.
