Message to clients

"I strive to provide a safe space for my clients to feel they can explore any issue without judgment. There is usually more than one evidence-based way to approach any issue, so I use the therapy techniques that fit my client best. Transitions, whether developmental milestones or unexpected changes in health or relationships, can bring up intense emotions. Anxiety disorders, depressions and sometimes scary thoughts will often appear or worsen at these times. Some clients feel better after one session just knowing they aren't alone. 

I treat all races, religions and sexual orientations with openness and a willingness to address and include ideas and discussions important to my clients. I have experience working extensively with Jewish clients as well as Muslim, Catholic, Buddhist and Christians of many denominations."

Treatment approaches

Acceptance and Commitment Therapy (ACT) Acceptance and Commitment Therapy (ACT) is a form of cognitive behavioral therapy that uses mindfulness and behavioral activation to help people learn strategies to live life more in the present, more focused on important values and goals, and less focused on painful thoughts, feelings and experiences. (learn more)
Cognitive Behavioral Therapy (CBT)In cognitive behavioral therapy, you work with a therapist in a structured way, attending a limited number of sessions. Cognitive behavioral therapy helps you become aware of inaccurate or negative thinking, so you can view challenging situations more clearly and respond to them in a more effective way. (learn more)
Dialectical Behavioral Therapy (DBT) Dialectical Behavior Therapy (DBT) is a cognitive behavioral treatment that often used to treat disorders such as substance dependence, depression, post-traumatic stress disorder (PTSD), eating disorders, and particularly chronic borderline personality disorder. It teaches skills such as mindfulness, pain tolerance, interpersonal effectiveness, and emotional regulation. (learn more)
Family SystemsFamily systems theory views the family as an emotional unit and uses systems thinking to describe the complex interactions in the unit. Family system therapy may be used to address conflict stemming from the family unit by working on a client's ability to maintain individuality while maintaining emotional contact with the group. (learn more)
Mindfulness PracticesMindfulness practices include but are not limited to developing awareness, attention, and remembering. In mindfulness-informed therapy, clients develop tools to become aware of what is occurring within and around them, so they can begin to untangle from mental preoccupations and difficult emotions. Self-acceptance and compassion are also core elements of mindfulness-informed therapy. (learn more)
Psychodynamic TherapyThe aim of psychodynamic therapy is to bring the unconscious mind into consciousness - helping individuals unravel, experience and understand their true, deep-rooted feelings in order to resolve them. It takes the view that our unconscious holds onto painful feelings and memories, and that the defenses we develop to ensure these difficult memories do not surface from our unconscious often do more harm than good. (learn more)
Supportive TherapySupportive psychotherapy is used primarily to reinforce a patient’s ability to cope with stressors by giving clients the opportunity to express their feelings and thoughts about the issues. Clinicians help patients learn how to move forward and make decisions or changes that may be necessary to adapt, either to an acute change, such as the loss of a loved one or severe disappointment, or to a chronic situation, such as an ongoing illness.
