Professional statement

Dr. Kay Mimaki is a licensed psychologist who works with adults navigating anxiety, trauma, cultural identity concerns, and the pressures of high‑functioning professional life. She provides a calm, steady therapeutic space where clients can explore their experiences without judgment and begin to understand the patterns that shape their emotional world. Many of the individuals she supports are managing chronic stress, burnout, relationship patterns, or the lingering impact of past experiences, and appreciate her grounded, culturally attuned presence.

Her therapeutic approach blends evidence‑based modalities—including CBT, ACT, CPT, IFS, mindfulness practices, and trauma‑informed care—with a collaborative, practical style. Dr. Mimaki helps clients build skills for emotion regulation and coping while also exploring deeper themes related to identity, family expectations, and cultural context. She is especially attuned to the experiences of bicultural and Asian American adults, offering a space where these complexities are understood intuitively rather than needing to be explained.

Dr. Mimaki brings more than two decades of clinical, academic, and assessment experience to her work. Her background includes long‑standing independent practice, service as a Qualified Medical Evaluator for the State of California, and over a decade as an Associate Professor and Program Director at Alliant International University’s Clinical Psychology program in Japan. This combination of clinical expertise and cross‑cultural experience informs her ability to support clients with nuance, depth, and clarity.

She offers therapy exclusively via secure telehealth to adults throughout California, providing flexible scheduling that fits into clients’ busy lives. For those using out‑of‑network insurance benefits, she partners with Thrizer to verify coverage and streamline reimbursement. Dr. Mimaki’s practice is designed to be accessible, supportive, and grounded—an environment where clients can feel understood, steady, and better equipped to move through challenges with confidence.


Message to clients

Starting therapy can feel like a big step, and my hope is that you feel supported from the very beginning. I work with adults who are navigating anxiety, trauma, cultural identity concerns, and the pressures of daily life, and I aim to create a space where you can slow down, reflect, and feel understood. You don’t need to have the “right” words or a clear plan before we begin — we’ll figure things out together at a pace that feels manageable.

In our work, I focus on helping you build practical tools for coping while also exploring the deeper patterns that shape how you think, feel, and relate to others. I approach therapy with steadiness, curiosity, and respect for your lived experience. Many of my clients appreciate having a space where they don’t have to explain cultural context or minimize what they’re going through, and where their internal world can be met with clarity and compassion.

If you’re unsure whether therapy is right for you or what you want to focus on, that’s completely okay. Our first session is simply a chance to get to know each other and see what feels most important to you right now. My hope is that you leave each session feeling a little more grounded, a little more understood, and a little more equipped to move through whatever you’re facing.
