Provider on this visit (2nd) seemed to listen more attentively and were able to come to an agreement on one of my medications that I have taken for many years. I also provided more information on my financial situation and discussed ways to keep medical costs down.

Dr. Decker was well informed about my health history for our first visit. He was very respectful and spent as much time as I needed to talk through my health questions and concerns. He has provided excellent care during my visit and with follow up lab results.
Aug. 10, 2019
He was exceptional in having a complete understanding of my rather complicated medical history and had reviewed the recent record. He also spent a good deal of time discussing new concerns and explaining options. .

I greatly appreciated that I was not rushed and did not feel like I was on a assembly line. The receptionist patiently talked me through the check-in procedures, the nurse who took my weight, blood pressure and initial questions talked me through everything efficiently but, did not rush me. Dr. Decker was excellent. He discussed my medical history, previous test results and future plans. Although he was too the point and did not get distracted with small talk I felt he was truly interested in my health & well being at all time.

doctor listen very good for my needs

Dr. Decker is a compassionate doctor who takes his time and is very thorough. When I, his fiancée, set up this appointment the receptionist wanted to know if she should write down "depression" because it's "personal". Isn't any reason. for the appointment "personal"? I find that very odd as if it is something to be ashamed of? I think that should be addressed with your employee. Thank you.We love Dr. Decker!

This was my establishment of care visit with Dr. Decker so my first time seeing him. He was fantastic. I am excited he is my new PCP. Even though I have a very extensive medical history. he knew most of it very well already. i respect and appreciate that an incredible amount

Dr. Decker and his staff collect pertinent information and are then very proactive in the treatment of any concerns. I could not be in better hands.
April 18, 2019
was treated like a actual human being and was actually at ease and able to express myself and was listened to by someone who actually cared
April 17, 2019
*Dr. Decker is exceptionally open-minded and he's a very good listener . I feel like he's a partner in my health care - he doesn't just give his feedback, he listens very well and is relaxed rather than rigid or stand offish.

I'm a new patient and was pleased.

very interested in my well being and very polite
March 29, 2019
I felt very well taken care of. I brought a few new issues which were discussed and explained. HM items were discussed, labs were ordered and explained why. Lab results were sent quickly and explained as well. I can offer no complaints. Dr. Decker is phenomenal!
March 18, 2019
my only concern is his wanting to push statins on me. I'm not on board. neither is my cardiologist. not a huge issue. But, as time goes on ... we'll see.

Dr. Decker is primary care for both me and my wife, so knows about the mix of issues we are dealing with, including her Alzheimer's. We typically see him together and have our appointments coordinated, which is helpful. On this last visit, while my wife was out of the room for something else, he asked me about how well I am handling our stresses and suggested he could refer me to a counselor to help with that. I very much appreciated this and his sensitivity to our overall situation. We are very happy and satisfied with the totality of our care through Froedtert.

Dr Decker is the most caring and concerned primary doctor Iv'e ever had. He has helped me through somewhat life threatening health problems over the last two years and continues care for me. He gives me personal phone calls to address certain health issues and what the next step should be. Not something any other doctors do. Ususally it's a nurse that calls with information. The personal communication is great I would refer him to anyone!

Everyone that I have come in contact with from valet parking staff and nurses and all staff members have been exceptional. I have great respect for all that I have come in contact with.

This was my first doctors visit to any doctor in about 15ish years. I didn't know what to expect, or what I was doing. But the staff was really helpful, and it was almost like they knew I had never been to a doctors as an adult without me needing to say anything. Now we will see if they keep doing that and it makes me feel like I'm stupid lol, but for my first visit that was awesome! Also, I smoke cigarettes. And as a smoker, I always feel like I am intentionally disrespected by those around me for the decision I made, even if I am not smoking at that time. I was really nervous about seeing a doctor because of this. While he mentioned smoking being bad, it was in one sentence without being very descriptive. Towards the end he asked me if I ever thought about quitting, and he accepted my answer before moving on to other topics. It really was a great experience.

*Dr. Decker was kind and respectful. Extremely knowledgeable and competent. I highly recommend him!
Feb. 14, 2019
I thank *Dr. Decker very much for separating my husband & I in different rooms, we usually come together, he make me so relax during our visit since we came together. There are concerns about themselves that only she wants to share with her doctors, I have so much faith, in him.
Feb. 13, 2019

Very thorough and knowledgeable.

Dr. Decker really listened to me and took more time with me than I anticipated. he was very professional and a great doctor. the only feedback is something more personal in the sense that our personalities are just different. where I am goofy and down to earth while Decker was very professional and a true clinician. because this was our first appointment, I expected that though. I guess time will tell the more I get to know him every year. he was great and I know I can trust him. An excellent clinician!

Jan. 18, 2019
