When life feels heavy, scattered, or stuck, therapy can help you regain clarity, stability, and momentum. If you’re dealing with anxiety, depression, ADHD, relationship stress, family conflict, life transitions, or the emotional strain of aging, you don’t have to sort it out alone. Together, we can better understand what is keeping you off balance, strengthen coping tools, and help you move toward calmer thoughts, healthier relationships, and a more hopeful, grounded daily life.
I’m a licensed clinical psychologist who has been in practice for decades, and I tailor treatment to each individual rather than using a one-size-fits-all approach. In our sessions, you can expect thoughtful listening, a detailed understanding of your history, and practical, evidence-based support informed by CBT and my broad clinical experience.
If you're ready for support, reach out to schedule a session or request a free 15-minute consultation. My online practice, experience working with teens, adults, and families, and website booking options make it easy to take the next step toward feeling better.
