  • Providers take time to explain conditions and treatments clearly

Common complaints

"Dr. Pollack has been very helpful to me with my difficult pulmonary problems over the years. I am very grateful. He listens carefully, asks the right questions and seeks to bring relief."

— Vitals review for Dr. Alan Pollack

"The staff assistants and phlebotomists are rude and could care less. The doctors are competent and attentive. The basic problem for RIMG is its pitiful attempt to communicate electronically (or by phone) with patients."
