I am a New York State Licensed Psychologist. I approach my patients' problems from a "biopsychosocial" perspective and utilize evidence-based practices, including cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT) techniques, in my therapeutic work. I have also completed Postpartum Support International's training in Perinatal Mood and Anxiety Disorders. 

I specialize in helping adults with:

  • Psychological evaluation and diagnosis of mental illness utilizing DSM-5-TR (Diagnostic and Statistical Manual of Mental Disorders) criteria
  • Depression, including bereavement, Major Depressive Disorder, and Bipolar Disorder
  • Posttraumatic Stress Disorder (PTSD)
  • Adjustment to chronic illness, including diabetes and Long Covid
  • Anxiety disorders, including Panic Disorder
  • Pregnancy-related (including pregnancy or infant loss) and postpartum mental health care

I received my bachelor's degree in psychology from Harvard University in Cambridge, Massachusetts in 1997 and my doctorate in clinical psychology from Indiana State University in Terre Haute, Indiana in 2006. During my pre-doctoral internship at the Northport V​A Medical Center, in Northport, New York, my patients were male and female veterans of WWII, Korea, Vietnam, the Gulf War, Iraq, and Afghanistan who were struggling with posttraumatic stress disorder (PTSD), major depressive disorder (MDD), adjustment to physical illnesses, and substance-related disorders. From 2006 until 2008, I was a member of the Assertive Community Treatment Team at the Pederson-Krag Center in Smithtown, New York, and helped individuals with diagnoses of schizophrenia, bipolar disorder, and MDD by visiting their homes and working with them and their families. From 2009 until June 2015, I worked with short-term and long-term residents at the Gurwin Jewish Nursing and Rehabilitation Center in Commack, New York on issues ranging from adjusting to having a chronic medical illness, to grieving the loss of a spouse or child, to coping with​ chroni​c PTSD, and I did similar work from 2014 to 2015 at the Long Island State Veterans Home in Stony Brook, New York.

In January, 2014, I started my private practice in S​mithtown, and in November, 2015, I opened an office in Mount Sinai. Since March 2020, I only provide telepsychotherapy (virtual therapy) services.

In addition to my clinical work, I taught classes in Abnormal Psychology and Personality Psychology at St. Joseph's College in Patchogue until May, 20​17. I am an active member of the Suffolk County Psychological Association (former President, President-Elect, Programming Committee Chair, and Treasurer), a member of the New York State Psychological Association, and a member of the American Psychological Association.
