Message to clients

“I am dedicated to meeting the emotional and psychological needs of my clients. My approach is to be caring and compassionate, while also trying to be direct in guiding clients through their process. I believe that counseling can help individuals and families move in new directions, fostering growth and a sense of well-being. I work with people from all walks of life. Change is possible; what we long for is not beyond reach.

My goal in working with clients is to help them gain the skills needed to cope effectively with life’s stressors, engage meaningfully with others, manage distressing feelings, regulate emotions, reduce impulsivity, increase self-confidence, communicate effectively, and to learn to express their needs successfully. I am a firm believer that we all want to do well.”

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.
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)
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)
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.

Professional endorsement

Diana was the first therapist I saw; we worked together when I was in high school. At first, I was very hesitant to seek therapy, and she made the whole process seem so comfortable and non-threatening. I really wasn’t used to speaking about myself or my feelings at all, and she helped me normalize that, realize the importance, and see my anxieties from a clear point of view, without ever coming off as patronizing or judgmental. She cares deeply about her patients and a decade later, she remains the best therapist I have ever worked with!
