I have been a patient of Dr. Pearsall for more than 10 years. Most importantly, Dr. Pearsall has improved my quality of life significantly. With my disease, I'm still able to play tennis and feel good about life. The doctor’s office staff are very friendly and helpful. I recommend Dr. Pearsall to anyone who wants to stop aging or who feels weakness and sleepiness and other discomforts, which he or she did not feel when younger.
