Dr. Eng is the only doctor after many years of searching that finally realized my grandson had a lack of growth hormone. By the time my daughter and I found Dr. Eng, we had taken her son to several other "specialists". I begged him for his help as my grandson was 12 years old and was the size of about a 7 year old. He had not even started the process of puberty. He immediately ordered all kinds of tests and then my daugher followed through with a full day of tests at Long Beach Memorial Hospital. Thankfully, Dr. Eng found out that my grandson was lacking the proper growth hormone and his staff also helped my daughter acquire the proper documentation to receive growth hormone therapy thru the drug company for the first year for free (as it is very expensive). I am pleased to say my grandson is now 14 years old and is now normal size for his age. My grandson still has to give himself shots 3 times a week, and Dr. Eng keeps a close eye on his progress to make sure he's always on the right dose. As far as our family is concerned he gave our grandson a normal future.
