OUR NEW OFFICES Located at Las Colinas in Irving, Texas, just 10 min from DFW Airport. I continue to juggle the responsibilities of running a busy endocrinology practice with the continued desire to gain out to those individuals who financially or logistically are not able to be my patients.

Avoiding Hysterectomy Report

Hysterectomy is the second most frequently performed surgery, after C-section, for women of reproductive age in the United States. The latest studies show that approximately 600,000 hysterectomies are done each year in the U.S. and HALF of these women also have their ovaries removed at the time of their hysterectomy.

Foods R Us Report

We have a very intimate relationship with food. We take food into our bodies and it actually becomes part of our living selves. That is why it is so hard to change eating habits and patterns. We each have an early history that goes back to the eating patterns that we were taught as children, i.e. the favorite foods we were given by our mothers or fathers.

Growth Hormone Therapy Report

First of all growth hormone is a hormone which naturally occurs in our bodies. It is made by the pituitary, a gland located beneath the brain. The pituitary is considered the master gland of the entire endocrine system and it regulates the production of all the hormones in the body. Growth hormone gets its name from the fact that it is responsible for a child growing to become a full sized adult.

I called in just to get information, I was diagnosed with hypothyroid last year and ended in the hospital, it has been a very tough battle i take a lot of medicine and thyroid support as well I was going threw a tough period and need to get a doctor in Dallas asap!, her assistant or secretary or what ever she is was beyond rude, no manner or respect, I dont know if that lady was having a bad day but the way she spoke or did not take the time to let me speak was not acceptable, I wish I had gotten different experience because all I am looking for is just simple help, I was running a fever and very swollen and just needed help, as well as regardless the cost, her secretary spoke to me in a tone of not affordable.

The only thing I know is that I would not be calling back for help, I am still in search of a doctor and I am doing my research so I hope I can find some one with a kind heart soon.

This woman is ahead of our time. Saw her many many times 5 yrs ago. I will never regret seeing her. She is expensive since it is concierge medicine after all. But she is worth every penny! My only regret is that I am not still in Dallas so I can easily see her on a regular basis. She is a brilliant physician!

Report

I had about lost hope when I found Dr. Johnson. I'd seen 2 previous endocrinologist for high (1200+) triglycerides. They wanted to put me on statins, then fibrates & change my diet. She was the first Dr. to take her time & find out the true cause of the problems I was having. She did a bunch of tests, started me on hormone replacement therapy & my triglycerides are normal. My anxiety is gone & I feel good again.
