Today we’d like to introduce you to Karen Sun.
Hi Karen, so excited to have you on the platform. So before we get into questions about your work-life, maybe you can bring our readers up to speed on your story and how you got to where you are today?
For most of my life, I lived in survival mode.
I grew up in Taiwan in a poor family, with parents who were struggling and emotionally unavailable. As a child, I did not feel safe, loved, or protected. By the time I was five, I already believed I wasn’t good enough. I stutttered, I stayed silent, I carried the shame and fear with me.
And yet, I pushed myself. I studied hard, and I became a doctor. I came to the United States, and I built a practice from scratch. On the outside, I was successful. But on the inside, I was still carrying those wounds. I worked myself to exhaustion, I stayed quiet in my marriage, I ignored my own needs, just as I had learned to do as a child.
Then came my turning point. Menopause hit me—hard. Burnout hit me even harder. And suddenly, the way I have been living wasn’t sustainable anymore. I couldn’t ignore myself any longer.
That was when I began a new journey, not just as a doctor, but as a woman learning to heal herself. I discovered functional medicine and biidentical hormones, which changed how I practiced medicine. I also discovered meditation, self-acceptance, and the practice of learning to love myself–which changed how I live my life.
The transformation was profound. I went from a fearful, exhausted, burned-out woman–to a confident, joyful, empowered healer. I found my voice. I began to speak publicly, to teach, to write. I completely changed my practice, no longer tied to insurance companies, and built a cash-based model that allowed me to truly serve the women who came to me.
Today, 20 years later, I see the contrast so clearly, who I was then and who I am now. And that transformation is why I can help other women step into their own healing.
Because I know what it feels like to live in survival mode.
And I know it’s possible to step out of it–into freedom, health, and joy.
Would you say it’s been a smooth road, and if not what are some of the biggest challenges you’ve faced along the way?
Going to medical school was not easy. Coming to a new country with a different culture and language was not easy. Finding a residency as a foreign medical graduate was not easy. Starting a private practice from scratch was not easy. Getting married, staying in a difficult marriage, and later going through a divorce were not easy. Raising a child was not easy.
But through all those challenges, I’ve learned that every difficulty has shaped me into a stronger, more compassionate, and resilient person. Each hardship became a lesson that deepened my understanding — not only of myself, but also of the people I cared for as a physician.
Thanks for sharing that. So, maybe next you can tell us a bit more about your business?
I am a board-certified internist with additional training in holistic and integrative medicine. In the last 20 years, I have been practicing functional medicine, helping people from the inside out.
While I am best known for my expertise in bioidentical hormone therapy for menopausal and perimenopausal women, my practice goes beyond hormones. I focus on gut health, nutrition, detoxification, and helping patients reduce toxic exposures.
What truly sets me apart is my emphasis on mind-body medicine. Over the years, I’ve realized that the real epidemic in modern society is chronic stress, which underlies so many physical illnesses. My goal is to help people reconnect their mind, body, and spirit — because true healing only happens when all three are aligned.
What makes you happy?
What truly makes me happy is being in nature — whether hiking in the mountains or walking on the beach. When I am surrounded by nature, I feel deeply connected to God, the creator. The second thing that brings me joy is spending quality time with good friends — especially like-minded friends with whom I can share stories, laughter, and genuine connection. Those moments of being understood and loved mean a lot to me. And finally, one of my most significant sources of happiness is playing with my grandson. He is only 15 months old–so innocent, so curious–and every time I’m with him, I feel pure love and joy.
