very thorough, best
Dec. 17, 2019
unlike many physicians, he spent an appropriate amount of time with me. not too much and not too little..just the right amount.
Dec. 17, 2019
doctor and his nurse fantastic! front desk poor attitude
Dec. 11, 2019
He is very in tune to my condition and always explains well plus listens to my concerns
Dec. 9, 2019
like the thoroughness of appointment in my health history and making sure they had my info from the past
Nov. 14, 2019
Dr. Shaker is an excellent MD and I travel 3 hours total just to see him!
Nov. 12, 2019
positive experience with Dr Shaker and his staff. very friendly, and knowledgeable . I was very pleased with our encounter and look forward to working with them in the future
Nov. 7, 2019
People were respectful and considerate. Areas for improvement - 1) I was asked to fill out a health questionnaire that the nurse would take. No-one asked for it and I forgot about it while I was waiting in the exam room. 2) The doctor mixed up my health information several times and was not current on the records that were sent to his office. He seemed knowledgeable and considerate but perhaps too busy.
Nov. 1, 2019
this office and provider were very organized, they knew about my history, and were very knowledgable. They took a good amount of time to go over my records and history and work out a plan of treatment.
Oct. 16, 2019
My experience with Froedtert and all of the physicians and staff has been nothing but excellent
Oct. 2, 2019
The care i received was exellent. I only wish i could get in to see doctor sooner. My first appointment i had to wait 5 months before there was a available opening.
Oct. 1, 2019
This was my first time seeing Dr Shaker. I felt he was attentive and thorough and I never felt rushed. I appreciate that.
Sept. 6, 2019
"Treatment" would be determined my the results of the tests which I trained via email (my chart) . No calls or explanation but I should set an appt. to follow-up... but is very difficult to get an appt. (almost 3 months!) That's a long time to understand the issues?
Sept. 4, 2019
Dr. Shaker is easy to talk to, explains everything, and answers all my questions. I like him very much!
Sept. 3, 2019
I spent my first 20 to 30 minutes of my appointment with the admitting person going through the current list of prescription meds and supplements that I am taking. I'm not so sure she got everything correct so I was glad when Dr. Shaker went through everything with me again. Dr. Shaker seemed very thorough and respectful as a doctor (this was my first appointment with him). There was a lot of information to take in at my appointment so after I left, I found that I had more questions regarding the urine collection, where I can go for physical therapy, and the proposed osteoporosis medicines that he wants me to think about. It is rather difficult to get another appointment with him so I have made a tentative appointment and have been placed on a waiting list to see if it is possible for me to get in sooner. I know I have access to online information so I will probably contact Froedert through "My Account" with questions that I have.
Aug. 30, 2019
Dr Shaker clearly explained my choices for further treatment and included his opinion on which would be best which I appreciated very much
Aug. 21, 2019
great eye to all details & really showed concern
Aug. 20, 2019
am to follow up in 3 months but no opening for 5 months and cannot afford to see np and md at visits
Aug. 11, 2019
he is as very thorough, not rushed, genuine, and showed knowledge and concern for my conditions. he asked appropriate questions and gathered all the information he would need in order to have a complete idea of my medical history. he was not rushed
Aug. 8, 2019
This was my first visit with him. He ordered blood work and other tests that will be done soon. He is one of the most thorough doctors I have ever had. If I would have been able to see him years ago, I believe I would not be in the condition I am now in. Osteopenia would more than likely not have turned into osteoporosis. Too bad the other endocrinologists were not this caring or thorough.
Aug. 7, 2019
The Froedtert campus is a mess. I was given directions which told me to follow signs to parking garage B.....ONLY PROBLEM IS THAT THERE WERE NO SIGNS TO PARKING GARAGE B! I CAME UPON IT STRICTLY BY ACCIDENT. AND THEN THE CONVOLUTED DIRECTIONS TO THE DOCTOR'S OFFICE INCLUDED TWO DIFFERENT ELEVATOR RIDES.....I WILL NEVER SEE THIS PROVIDER AT THIS LOCATION AGAIN. I would much prefer Mequon or another location, keeping in mind that this provider is not my primary care physician who is with Columbia St. Mary's. BUT...the doc I saw is an excellent physician in the specialty I needed.
Aug. 3, 2019
Dr. Shaker spent a lot of time with me, answered all my questions, was respectful of my right to make the final decision on my health care choices.
July 17, 2019
He has too many patients. Getting an appointment is hard and takes a LONG lead time.
June 27, 2019
Plenty of time for me, good answers to questions, good examination - no negatives.
June 26, 2019
10 - Every thing was done in a timely manner. All our questions answered.
June 25, 2019
Dr. Shaker was attentive, respectful, and included me in the discussion of my care, including asking me if it was okay to do blood tests and x-rays during my visit.
June 20, 2019
Very open to discussion.
May 29, 2019
Dr Shaker listens to his patients and works well to find a treatment plan that works for them. I wish other doctors were this accommodating.
May 29, 2019
Explanations great, give options, ask my opinion & if I was satisfied.
May 20, 2019

April 18, 2019
Dr. Shaker is an expert in osteoporosis. He was my second opinion. His knowledge and plan of care was outstanding.
April 17, 2019
Dr. Shaker seems to care about me.
March 26, 2019
Dr. Shaker was good listener & cared to get diagnosis correct. Took way too long to get initial apptmt. - 8 mo. (6 mo. initially, then rescheduled by provider).
March 21, 2019
Dr. Shaker provides a relaxed, comfortable environment making it easy to ask questions.
March 19, 2019
He would ask the questions first - and then we (my hubby) could talk last was not concern with my diabetes, just my high calcium.
March 13, 2019
Resident who interviewed me prior to seeing Dr Shaker had not reviewed my medical history and, there were a couple of errors in'the history which I hope were rectified.
March 8, 2019
!st time being seen foe Osteoporosis. Very good doctor. ordered x rays of spine. also PT and other test in future. Very happy and will follow up in 4 months.
Feb. 27, 2019
I love MyChart. I get information VERY quickly and phone calls if needed. If the doctor I being with does not know the answers, they refer me to someone who might.
Feb. 26, 2019
I found the provider's care very thorough, explained everything fully, and ordered lab tests, etc. to obtain more information. Everyone at the clinic is very helpful & answers promptly. I find Froedert very organized. I like the receptionist at the front for all departments checking patients in, and then sending them to the appropriate department.
Feb. 19, 2019
His explanations were very clear and easy to understand.
Jan. 29, 2019
Dr. Shaker is very personable and knows his specialty very well.
Jan. 23, 2019
After 2 biopsies I was told my condition is undiagnoseable. This is difficult because I would like an answer either way.
Jan. 21, 2019
Dr. Shaker is very understanding, he listens to what I say, and explains what he is doing and why. I'm at ease whenever I'm with him and his team.
