I came to Dr. John because I was feeling miserable. I started with thyroid problems and hair thinning. Dr. Duong is treating me for multiple conditions. He found out with a blood test what my other doctor couldn’t find. I feel much better after one month. I recommend him to anyone, thank you Dr. John for everything. The other doctors don’t find the cause, they only treat the symptoms. Dr. Duong is treating me, and I feel wonderful. My regular doctor, who I’d been with for more than 10 years. He said it was all in my head. I had insomnia, my blood sugars and cholesterol was killing me. Dr. John found out exactly that.

My name is Nancy and I happened to come across Dr. Duong’s reverse thyroidism on the internet so I came in and checked it out. I’m a nurse, so I’m really trying to get focused on my health instead of helping everybody else.

The labs Dr. Duong does are far better than what the regular doctor does because he looks at the functional level, not the standard values the lab says is normal. If you go with those, I would be normal, but I’m not.

I’m trying to get rid of the lack of memory, the fogginess in the morning, the tiredness all the time, the weight gain. He’s definitely going to be able to help me. He’s willing to treat the cause and not just the symptoms. If you have a chance to come, you need to come on in and give him a try.

I have been suffering with hypothyroidism for a number of years. I have seen quite a few doctors for this. They prescribed the thyroid medication, but it didn’t seem to help take away al the symptoms or help me feel better. I was tired all the time, a lot of hair loss, no energy, couldn’t think clearly, brain fog, and feeling like I needed a lot of sleep.

When I first came to see Dr. John, he sent me to do specific lab tests and blood work to determine what my problem was. I found out that its Hashimoto’s, and he put me on a diet regimen specifically to increase metabolism. I’ve felt a significant improvement after taking the supplements. I odn’t feel like I have to take four naps a day anymore.

Dr. Duong knows how to help people with this type of disease and really make a difference in peoples’ lives. Dr. John really listened to me and just knew what I was experiencing.
