Dr. Saff listened attentively, asked great questions, and thoroughly explored my condition. She made me feel very well cared for, and confident that we would soon better understand my problem and make it better. She is truly outstanding in her work - thank you! The nurse (apologies I do not recall her name) was equally excellent - ensuring I was happy and comfortable, while administering blood pressure and breathing tests. The "feel" of the entire visit was just great :)

As my situation and length of illness goes over 20 years it's very complicated to explain to her, she waited patiently even though it's very difficult for me to explain of my problems and concerns yet she was kind and listen attentively and respectfully and I appreciate that very very much. Because when you have so many mysterious symptoms and concerns and have gone to literally dozens of doctors, she still gave me some hope that maybe this doctor will find the answers of why I've been so sick. I hope she finds the cause of my Immune Deficiency .

Dr. Saff is just excellent. Her summation of my medical history goes back a couple decades and is a summary I carry when I travel and may need to brief someone on my history. I saw her two days after a TIA and she asked if she could help with the referrals for the recommended follow-ups, and did (thank you). She is very patient with my efforts to describe my issues and reassuringly thorough in addressing them. I feel quite confident in her care.

I don't know if there was communication between nurses and doctors -- but both were good communicators, warm and friendly, knowledgeable. The front desk was also terrific -- very helpful in arranging future appointments. I learned a lot from Dr. Saff -- some of which I've already put into practice -- and once the testing is done I may be able to streamline my self care, once I know what is really causing the skin allergies. I'm very thankful.
