I live about 100 miles North of St. Louis, Mo. & 200 miles South of Chicago. My father is 72 years old with P.D. & has done well since diagnosed almost eight years ago. His condition is slowly deteriorating & although his primary care physician seems interested & is very helpful, we have been very disappointed in the few local specialists. They don't seem interested & are not helpful. As time goes on, I will want to find a first class specialist & am willing to travel some to see him with my dad. any suggestions appreciated. Thanks / Woody
