Hello, My name is Mija Lee. I am passionate about helping my clients regain their inner strength and navigate life’s challenges. I offer both virtual and in-person sessions for clients in California.
Since 2017, I have had the privilege of working with children, adolescents, and adults in outpatient mental health clinics and school districts. As a traveler, therapist, and firm believer in positive thinking, I bring a wealth of diverse life experiences and insights to my practice. These experiences have given me a deep understanding of the overwhelming stressors, relationships, jobs, and uncertainties that we all face. I believe that by confronting and overcoming these challenges, we can emerge stronger and thrive. I am truly grateful for the experiences and people who have shared their lives with me, showing me the transformative power of good therapy. I look forward to the opportunity to support you on your journey.

What can you expect to take away from sessions with me ?
​
Starting counseling requires a lot of courage. In our first session, I focus on making my clients feel comfortable and connected. We discuss their expectations, address therapy-related concerns, and answer any questions to help them understand the therapy process. Clients are encouraged to share their current struggles freely and explore how therapy can be beneficial for them.
I also love to provide resources and practical skills that can be immediately useful in addressing urgent needs and alleviating physical symptoms such as panic and dissociation.
​
My biggest strengths.
​
My clients describe me as light-hearted, personable, energetic, resourceful, and occasionally funny. I consider myself a rigorous student, continually learning about counseling and staying updated with current research, helpful tools, and new ideas. This dedication significantly benefits my clients and has made a substantial difference in their progress.
