I work with individuals throughout the lifespan who are facing various mental health challenges, including: ADD/ ADHD, Mood symptoms: depression, irritability, low motivation Anxiety and panic, including social anxiety and excessive worry Stress after major life changes Difficult to manage emotional reactivity Difficulty concentrating, sleep issues, and fatigue Medication-related concerns: side effects and adherence Interpersonal or occupational impairments supportive guidance throughout treatment with a focus on holistic care
I offer clients a comprehensive care approach that is focused on each individual' personal needs. My approach includes personalized care for: safety planning, thorough assessment, evidence-based meds, practical skills (e.g. emotion regulation, sleep), psychoeducation, collaborative goal-setting, and support with school/work, family, and community resources.
Struggling doesn’t mean you're broken – it means you're human. As a PMHNP, I offer a judgment-free space to listen and help you find practical steps toward feeling better. You don’t have to do this alone. If you’re ready to talk, I’m here. Reach out anytime, and we’ll take the next step together.
