After 14 years of being under Dr. Emma DiIorio’s excellent care, she thankfully turned my well-being over to Dr. Maher. Although this was our first meeting after Dr. DiIorio’s departure, Dr. Maher had taken the time to familiarize herself with my medical history. All of her questions to me were on-point; her physical examination to determine my strength was complete; her suggestions on what I should be doing to minimize the effects of the myositis and how to proceed with my care were all very logical. I do feel extremely comfortable under Dr. Maher’s care…she
is extremely intelligent, knowledgeable, kind and caring.

Though late (I had a 4pm appt, waited 30 minutes in consultation room), she managed to smile, took the time to converse, strategize my health outcomes and didn’t seem hurried.

Dr. Ziglar is very thorough. She reviewed and discussed my blood work results. She discussed my current symptoms and noticed I had not had x-rays recently. She ordered them of my hands and knees, then reviewed them with me and then proceeded to inject my right wrist with excellent precision.

Dr. Maher is amazing! I call Dr. Maher and nurse Frankie the dream team. When I speak to my family members, they ask me, "Which doctor's appointment do you have today?" I respond, "I'm seeing the dream team today." They then know that I'm going to see my Rheumatologist, Dr. Maher. Always attentive, always investigating, always working to get to the bottom of my aches, pains, and many health issues. Dr. Maher is wonderful!

Dr. Maher is caring and passionate about helping her patients. She is very thorough answering and asking questions. She takes her time to talk to patients about treatment, reactions etc., even when she is running late for the next appointment. My husband who has RA and I appreciate very much her wonderful demeanor and knowledge.

I saw Dr Ziglar to discuss my treatment with Prolia injections for my osteoporosis and also for her to look at my knee which was hurting.
Dr. Ziglar was excellent at explaining my Prolia treatments, took an x-ray of my knee and thoroughly explained what the xray showed and how she recommended we treat it.
It was a very pleasant, satisfactory visit.

Very kind, patient and informative. Really felt that she listened and checked my history. Didnt feel rushed. Others during the visit were nice too. In reading info on treatment I have thought of some concerns I would like to ask her about before starting treatment.
