    My appointment with Dr. Treiber went very well. She was polite and very knowledgeable, both myself and my son had appointments. She was amazing in dealing with his eczema and prescribed him something that finally made him stop scratching! Much appreciated! Billy Wong Chin
    Dr. Treiber runs a great practice! Her office was very clean and her staff was wonderfully organized. She treated my son for his eczema and after only a few weeks on treatment we've noticed an amazing improvement! DEFINITELY RECOMMENDED! Diana Monteverde
