Hello, and welcome! Thank you for taking a few moments to learn more about me and how I work as a therapist. Have you ever wished you could press the pause button, step off the merry-go-round of life stressors, and create space for reflection, perspective, and change? Life can sometimes feel like an endless series of obstacles placed in our path to test our patience and resolve. At times, we all feel disheartened and may struggle with discouragement or hopelessness. Perhaps you, or a loved one, are living with feelings of anxiety, overwhelm, or sadness. Or maybe, despite your best intentions, you feel stuck in patterns of thought and behavior that prevent you from engaging fully and
authentically in your life and relationships.

I want to acknowledge the courage it takes just to pause and consider reaching out for support. Often, when people enter therapy, they recognize that something feels off balance. They may not fully understand the roots of their distress—and that is okay. Therapy is a place where you can bring the parts of yourself that feel messy or uncertain, and we’ll explore them together at a pace that feels right for you.

Finding a therapist who feels like a good fit is essential. A strong, trusting relationship is the foundation of good therapy. If my approach does not resonate with you, I’m also happy to refer you to a therapist I trust.

Therapeutic Approach
My training is grounded in Person-Centered and relational therapy. This means I will approach our work with empathy, authenticity, and deep respect for who you are and where you’re starting. You are the expert of your experience, and I will take time to listen and learn about your unique life story and cultural history. I believe that healing happens when you feel truly seen, accepted, and safe to explore all of yourself.

Evidence-Based Practices
I build upon my Person-Centered foundation with complementary, evidence-based approaches. For example, I integrate Emotionally Focused Therapy (EFT), which can help people tune into their emotions and better understand the patterns that shape their relationships. I also draw upon strengths-based and solution-focused strategies, Acceptance and Commitment Therapy (ACT), cognitive-behavioral tools, and mindfulness practices to support resilience, regulation, and symptom relief. In addition to bringing you tools for managing your life effectively, my approach may include clarifying values and taking meaningful steps toward living in closer alignment with what
matters most.

Collaborative Process We will work together to establish clear but flexible goals for therapy. I don’t view therapy as about “fixing” you. I see it as deepening your self-understanding, loosening the grip of old patterns, and creating the possibility of more choice, connection, and freedom in your life.

Clinical Focus
I provide psychotherapy services to adolescents and adults, supporting a wide range of concerns from everyday life and relationship challenges to more complex issues. I have a particular interest in the treatment of anxiety disorders, ADHD, self-esteem and identity concerns, women’s midlife transitions, as well as relational and attachment
patterns and parenting challenges.

Anxiety Disorders
If you or someone you love has lived with persistent anxiety, you know how exhausting it can feel and how much it can interfere with everyday life. Anxiety shows up in many ways—through cognitive, emotional, or physical symptoms—and can leave you feeling depleted.

These symptoms may arise from stress, trauma, or burnout, and some people are more vulnerable because of genetic or environmental factors. Fear is a natural response to threat, but when the nervous system goes into overdrive, it can begin to feel unbearable.

In therapy, we’ll work together to calm the nervous system, gently face the situations that trigger anxiety, and process past experiences that may still echo in the present. My approach is rooted in curiosity and compassion, helping you see your symptoms not as flaws but as signals guiding you toward safety, well-being, and authenticity.

ADHD
ADHD often brings a mix of challenges and gifts. It can feel discouraging to struggle with planning, task initiation, time management, or emotional regulation, especially when these difficulties are met with misunderstanding from others. Many people carry a sense of shame from years of being told they should “try harder,” even as they also bring creativity, sensitivity, and unique ways of seeing the world.

In therapy, we take time to understand how ADHD shows up in your daily life and relationships. Our work may include practical tools for managing tasks, exploring past experiences that have shaped self-esteem, and creating new possibilities for support and connection. The goal is not to erase ADHD, but to help you feel more at home in yourself, grounded in both your strengths and your challenges. Whether you have a formal diagnosis or simply suspect that you or your adolescent child may be living with
ADHD, therapy can provide support that makes a real difference.

Identity and Life Transitions
Questions of identity often surface at key moments in life—adolescence, marriage and parenthood, or midlife. These transitions can stir uncertainty as we strive to develop an identity that feels authentic, fosters acceptance, and aligns with our values and goals. For women, midlife may bring added challenges as hormonal and physical changes intersect with shifting roles, relationships, and reflections on past choices. Yet these same seasons also carry the possibility of growth, empowerment, and renewed authenticity.

In therapy, we also examine how early relationships and attachment experiences may have shaped your sense of self. At times, these experiences can leave people feeling uncertain about who they are, struggling to set boundaries, or finding it hard to advocate for their own needs in relationships. Within the safety of the therapeutic relationship, we can reflect on these patterns together, explore different ways of relating, and experiment with evolving authentic expressions of self.

Identity work may also include exploring sexual orientation or gender identity. I welcome and affirm clients navigating these journeys, offering a space of inclusivity where exploration and discovery are honored. Whether you are questioning, affirming, or reimagining aspects of who you are, therapy can provide support as you step into a life that feels more whole and true.

I draw on both existential and relational perspectives, supporting clients and their courage to face questions of meaning, values, and identity. This process is not about discarding who you have been, but about integrating your past with your present, so that you can move toward the future with a stronger, more enlivened, and authentic sense of self.

Attachment, Relationships, and Parenting
Our closest relationships often reveal both our deepest needs and our earliest wounds. Many people find themselves caught in cycles of conflict or distance that reflect patterns from childhood. In therapy, I help individuals recognize these attachment themes, understand how they play out in the present and in our relationships, and learn new ways of advocating for their needs while honoring the boundaries and needs of others. This work aims to strengthen the foundation for more secure, balanced, and fulfilling relationships.

Just as our early attachments shape adult relationships, they also influence how we parent and connect with our children. Children develop their sense of identity and security through their parents’ reflections, attunement, and guidance. I support parents struggling with boundaries, communication, and other daily challenges of raising children. Concerns such as temper tantrums, transition struggles, lying, frequent arguments, and other challenges are explored through the lens of attachment needs and addressed collaboratively in therapy. Together, we focus on cultivating skills that foster connection and harmony at home. We also work on strengthening the parenting alliance, reducing situations where children feel caught in the middle, and keeping theirwell-being at the center.

Parenting is hard, and some frustration is a normal part of the process. With support, those struggles can be validated and transformed into strengthened feelings of connection. Therapy offers a safe space to experiment, build trust, and nurture relationships that help both adults and children grow with greater security, confidence, and a stronger sense of self.
