    He is the worst doctor i have ever seen I would not have a dead dog see him. The office staff is rude and the medical asisstants are dumb they ask me questions then a nurse ask me the same and said nothing was charted from the asisstant . The office is a filthy place, no tv for my son to warch while i was being seem by this rude doctor.. I would never recommend any of these doctors to anyone.

    Worst doctor ever! I had h pylori and I went to see him in July and he kept sending me away saying I was just probably stressed or it was my diet.I got so sick and ended up loosing 30lbs.I finally demanded a endoscopy and they saw h pylori,gastritis and gerd! I was sick for 6 months before he would take me serious!I now have a lump on my right side and I've asked him to check it out and he completely ignored me! Will never step a foot in his office again! Also plan on waiting 2 hours to be seen!
