We use Internal and Holistic medicine to heal and nourish the mind and body. We specialize in finding the root causes of medical conditions that elude other practitioners.
Why We're Different
Our combination of Internal (Western) and Holistic (Eastern) medical knowledge is rare. This knowledge informs our unique treatment offerings and strategy.
A message from the FOUNDER
Dr. Karen Sun, M.D.
Board Certified in Internal Medicine and Integrative Holistic Medicine
Welcome! I’m Dr. Karen Sun, founder of the integrative Wellness Center in Orange County, California. I am a board-certified Internist and am also board certified in Integrative and Holistic Medicine.
Do you suffer from fatigue, weight gain, insomnia or moodiness after menopause? I’ve been there and was disappointed with conventional medicine’s approach to menopausal symptoms. After a lot of research, I discovered bio-identical hormone replacement therapy to be very effective. When administered via an implanted hormone pellet, treatment can reduce menopausal symptoms and also keep you feeling young and strong.
Do you have gut issues such as irritable bowel syndrome, bloating, or indigestion? I have been there too! I incorporated nutrition and nutraceutical treatment for gut issues and adrenal issues, as well as detoxification for weight loss into my life. I now offer the same treatments to patients.
As stress is becoming a modern epidemic, I also focus on stress management. I help patients build healthy life styles and change negative belief systems. I’ve also added regenerative medicine such as peptide treatment to my practice.
I helped thousands of patients achieve their health goals by treating the roots, not just the symptoms. If you’re not well and have been to many doctors without finding relief, my integrative approach may be your solution! On the other hand, if you’re healthy but want to slow down the aging process, I can help you too!
If you need further help, please don’t hesitate to make an appointment so I can design a treatment plan just for you!
