With over 35 years of experience in the mental health field, I provide a safe, compassionate space for healing and growth. I specialize in working with women navigating loss, divorce, grief, and life transitions, as well as men experiencing similar challenges. I also support therapists and professionals exploring their Latinx identity, cultural issues, and the impact of generational trauma. My approach is culturally attuned, strength-based, and tailored to each client’s needs, drawing from Cognitive Behavioral Therapy, Solution-Focused, Family Systems, and trauma-informed care.
My style is warm, compassionate, and collaborative. I create a safe space to explore life changes, loss, relationships, and cultural identity. I adapt my approach to your needs, using tools from Cognitive Behavioral Therapy, Solution-Focused strategies, and trauma-informed care.
My communication style is warm, direct, and respectful. I listen closely—not only to your words but also to the feelings behind them—so you feel truly heard and understood. I offer feedback compassionately and honestly, always aiming to help you see new perspectives and possibilities.
