  • "The entire office was a VIBE. That’s the best way I can explain it. Everyone down to the girls at the front desk were personable, professional, and so kind and caring. I only went here for a routine screening for clotting factors and was treated with the ut most care and consideration, so I can only imagine how they treat patients going for more in depth reasons. Rose, the doctor’s assistant was extremely thorough with background questioning, and a total doll. And Dr. Chu himself was caring, thorough, inquisitive, and extremely professional and reassuring. What an office !!"
