Grief counselors and therapists in Casselberry, FL

With more than 30 years of experience as a clinical psychologist, I am passionate about helping adults and older adults navigate life’s emotional, psychological, and cognitive challenges. I provide psychotherapy, cognitive rehabilitation, and neuropsychological evaluations, with particular experience supporting individuals experiencing anxiety, depression, memory concerns, adjustment issues, and the impact of aging or medical conditions. My approach is compassionate, respectful, and individualized, and I strive to create a space where you feel heard, understood, and empowered to improve your quality of life.

I have more than 25 years of experience assessing and treating adolescents, adults, and families. While I appreciate numerous approaches, my patients have stated that I provide a melding of both direct and indirect styles. In other words, my standard of care is challenging and supportive. More often than not, you won’t leave a session wondering what’s next.

Feeling overwhelmed, stuck, or ready for something to change? You don’t have to figure it out alone. I work with adults navigating anxiety, stress, life transitions, and relationship challenges who want more clarity, balance, and confidence. Together, we’ll untangle what’s been weighing on you and create a path forward that feels realistic and empowering. Therapy can be a space where you feel understood, supported, and able to move toward lasting change—at your own pace.

I work with teens, adults, and families who are facing addiction, mental health concerns, trauma, relationship difficulties, life transitions, stress, anxiety, depression, and barriers to personal growth. Many of my clients come to therapy feeling overwhelmed, stuck, disconnected, or ready to make positive changes in their lives. You may be struggling with shame, guilt, anger, repetitive thoughts, poor sleep, concentration problems, or the effects of trauma that make it hard to feel calm, present, or in control. I also support family members who are trying to manage the impact of a loved one’s substance use while learning how to set healthier boundaries.

I specialize in evidence-based treatments for patients suffering from anxiety, OCD, Depression, and trauma related disorders. These treatments are more effective and efficient than traditional therapy because they directly target symptoms. I provide specific exercises aimed at breaking behavioral patterns that maintain symptoms. Traditional psychotherapy emphasizes gaining insight which in itself often does not lead to symptom reduction. Changing what you do will you change how you feel.
