Testimonials

Dr. Lan has been helping me with my thyroid issues for three years now and I couldn’t be more grateful for her compassionate care and insightful medical advice. Her inclusive testing has helped me understand what my body needs and how best to provide it through dietary changes and supplements. Despite previously having half my thyroid removed, I’ve been able to get off medication and today am living the active lifestyle I love. I recommend Dr. Lan and her supportive team to everyone I know. Thank you!

G.Z.

Dr. Lan's approach — finding and eliminating the cause of my illness, rather than just treating its symptoms — made sense to me when she explained it at our first appointment. She really took time to get to know me, and to understand what I wanted from my medical care. After completing a series of tests and following Dr. Lan’s recommendations, I’ve seen a dramatic reduction in my symptoms and I am far less dependent on prescription medication. It’s an approach I would recommend to anyone facing a serious disease like my colitis.​​
