I started seeing Dr. Obara after being treated by 2 doctors who simply wanted to feed me drugs. After doing some extensive research, I decided to make an appointment and hoped for the best. Dr. Obara gave me my life back! He didn't just have an interest in treating my condition, he went the extra mile to find a treatment that would improve my quality of life. After crying myself to sleep for over 2 years, I feel like he gave me my life back. He is my angel on earth.
