A good friend recommended Dr. Dewyer.  I wish she would have done so years earlier.  
Dr. Dewyer is the best Dr.  Good listener/attentive.  Very knowledgeable.  Excellent advice.  Nonjudgmental.  Willing to spend as much time as necessary.  

I recommended Dr Dewyer to 3 of my granddaughters.  (All became his patients.)
