My goal is to help you gain clarity and uncover the strength within to overcome current challenges.

I earned a B.A. in Music Education from Howard University in 2005 and a M.A. in Clinical Mental Health Counseling from Marymount University in 2012.

If you are motivated and ready for change, I am here to support you on your journey to fulfillment and improved quality of life!

With over 30 years of clinical experience, I provide individual psychotherapy that is collaborative and affirming. I use an integrated therapeutic approach that draws upon evidence-based treatment interventions and creative modalities tailored to each client. I see clients who are navigating anxiety, depression, grief, trauma, adolescent/parent/family conflicts, personal concerns and life transitions. I will support you to identify patterns, develop coping strategies, discover strengths, find solutions, and gain a deeper sense of wholeness and well-being.

Looking for relationship help? To relieve the pain or find better ways to manage? The "secrets" of dealing skillfully with difficulties, differences and hurts, are not really secrets: you CAN learn these and many more relationship skills if you are curious, motivated and persistent. I'd like to help you: a) address and relieve your most pressing problems, b) set clear, realistic goals, and c) learn to avoid a tremendous amount of headache and heartache in the future.

Every patient's story is different, and every story deserves full attention. I bring more than five decades of experience across hospital, outpatient, and consultative settings to each session. I work with adults navigating anxiety, depression, trauma, and a broad range of challenges. My style is warm and direct. I will tell you clearly what I observe, what the options are, and what we can work toward together. Good psychiatric care looks at the whole person, and that is always where I start.
