Hello, I'm Dr. Sebastian Vasilescu, a board-certified psychotherapist (Licensed Marriage and Family Therapist). In a collaborative approach, I help guide clients work through the many reasons why they arrive at therapy. Clients seem to have a very clear goal of bettering their lives, and I strive to make this happen by helping clients free themselves to heal relationally, both in and out of the therapy room. I work with children, adolescents, adults, couples, & families with varying presenting issues, including anxiety, depression, family of origin issues, marginalized oppression, relationship issues, and addiction.
Life can feel heavy sometimes—uncertain, overwhelming, and out of balance in ways that are hard to put into words. If you’ve been carrying a lot on your own, it makes sense that reaching out for support might feel difficult, even vulnerable. I want you to know that those feelings are understood, and you are not alone in them.
You don’t have to figure everything out by yourself. I’m here to gently walk alongside you as you begin to take those first steps—at your pace, in your way. Whether you’re feeling stuck, disconnected, or simply tired, this can be a space where you’re allowed to just be, without pressure or judgment.
I approach therapy with warmth, care, and deep respect for your unique story. Together, we’ll create a space where you can feel safe enough to express yourself openly, explore what’s been weighing on your heart, and begin to reconnect with yourself and the relationships that matter most to you.
With extensive experience working with adults, I tailor each session to your needs, honoring where you are while gently supporting where you want to go. Healing doesn’t have to happen all at once—and you don’t have to do it alone.
My name is Rosa, but everyone calls me Rosie. I am a bilingual English and Spanish-speaking Psychiatric Mental Health Nurse Practitioner. I’ve been a nurse since 2007, and working in mental health has always been my passion and a source of dedication. I’d be honored to walk alongside you on your journey to healing. You don’t have to face these challenges alone. Healing is possible, and you are not alone. I earned my Master’s degree with honors from West Coast University. I take pride in helping my patients develop personalized plans to improve their well-being and successfully adjust to life changes. My approach is rooted in patience, empathy, and respect.
Outside of work, I enjoy spending time with my dog, Yoshi, who is full of personality and love. I’m passionate about traveling for pleasure and for work with Liga International Flying Doctors of Mercy. I love connecting with nature and those in need, which helps me stay grounded and balanced.
I believe people carry far more strength, clarity, and resilience than they often realize. My role is to help you understand the emotional patterns and internal narratives that shape your experience, so you can move through life with greater freedom and self‐trust. I’m engaged, attuned, and honest in the room — offering reflection, insight, and steady collaboration as we explore what’s happening beneath the surface. We work at a pace that feels grounded for you, creating space for real change to germinate.
I have worked with a variety of clients of all ages and cultural backgrounds. My primary focus has been on individual therapy but enjoy working with couples and families as well. I bring empathy, unconditional positive regard, and genuineness to all of my therapy sessions.
Recognizing when you're overwhelmed isn’t weakness—it’s wisdom. Whether you’re stuck in familiar painful patterns or navigating a new life transition, I’m here to help guide you. Since 2011, I’ve supported diverse clients across inpatient, outpatient, substance use, and crisis settings. I offer contemplative, trauma-informed care for LGBTQ+ adults, veterans, artists & creatives, and high-performing professionals, and I help people of all backgrounds deepen self-understanding and work through questions of identity, meaning, and purpose.
I'm a Licensed Professional Clinical Counselor with nearly a decade of experience across community mental health, hospital, and private practice settings. I offer sessions in English and Mandarin, and I specialize in working with individuals navigating anxiety, burnout, life transitions, grief, and relationship challenges. I have a particular understanding of how culture, family history, and identity shape our inner lives — especially for Asian American and immigrant communities
