Very, very, very excellent doctor. Very caring, very personal, very knowledgeable about everything concerning my complicated medical problems. Best doctor I have ever known. Wonderful human being!
Dr. Cathy Riker is AMAZING! On a 1-10 scale, I'd rate her "15" or more!! She is singularly THE BEST physician I have ever encountered. Her thoroughness, interest, communication, personal concern is evident on every visit I've had with her (3 prior, I believe). As I told her, she is THE ONLY DOCTOR I've had that ASKS QUESTIONS, which is extremely beneficial and I find myself saying, "Oh, yes....." and fill her in. If the patient doesn't come prepared with questions, most other doctors let it go at that, do their minimum procedures and bid you adieu. Doctor Riker merits an award for her OUTSTANDING attention to her patients. I am sure that you've heard rave reviews about her in the past. Other physicians in your system should regard her as a role model and seek like-kind behavior. SHE IS A KEEPER!!!!

I love Dr. R. Ker she always spends whatever time is needed to discuss what's going on. I also like that she keeps up on recent research, etc.
Dr. Riker is incredibly kind and helpful. I often struggle to deal with having Lupus, but always feel like Dr. Riker cares about me and my health. She listens, treats me like an adult, solicits my input, and is always compassionate. I appreciate her very much.
in the course of this visit I became very dizzy and nauseated. Dr Riker went out of her way to assist me with a drink, cool cloth, prescription for antinausea meds etc. I began vomiting for quite some time and she was very helpful and supportive. Once I stabilized she helped me change into a dry shirt and clean up. I could not have asked for a more compassionate response to my situation. Dr Riker is an exceptional caregiver.
I have already recommended Dr. Riker to someone who is looking for a specialist in rhuematology.
In my first visit, I was in a most stressful state. The provider patiently examined me, called for history from physicians, order tests, and explained the possible treatments pending the test results. Carefully calculated the medicine dosage according to my size, gave warning of possible of conflict of medicines I might used. The provider is capable, confident, caring. I am a skeptic, but this provider has earned my trust.
Dr. Riker is amazing. She is caring, compassionate and stays up on the latest research which makes me feel comfortable.
Dr. Riker is fabulous, too! I have been her patient for approximately 20 years.
