Dr. WEISSIG is an exceptional specialist. I wish Providence had 200 more Dr.'s like Dr. WEISSIG!! He is always going that extra mile.He has found things about my husband's and myself's health that no other doctors had found. He goes beyond his capabilities and always has, we have seen him for years. We always highly recommend him to our friends. If you had at least two hundred more physicians like him, your hospital would be close to a number one hospital. He is considerate, professional, articulate, caring & listens and always has an exceptional professional opinion. Great, great, man...
