I am so happy that Dr. Jake Decker is my new Primary Care doctor! My recent visit with him was a transition from a long time relationship with my previous Internal Medicine/Primary care doctor with whom I hadn't been satisfied with for several years. Dr. Decker is everything an excellent Primary Care physician should be and I am so glad I finally sought care from someone new. I feel very confident under his care and look forward to the changes we agreed on regarding medication and a referral to a new psychiatrist at a clinic he recommended. The high blood medication he prescribed has lowered my previously high blood pressure to a healthy, normal range immediately.

This was my first visit with Dr. Decker. Something happened which resulted in my appointment being cancelled without my knowledge, yet when I showed up at the appointment time, staff and Dr. Decker made a great effort to make sure I could see the doctor that day and with little waiting time, which I very much appreciated. Dr. Decker was able to see some of my history via computer but not all, however he did spend much time gathering information. He was very pleasant. He allowed me to ask as many questions as I wanted and gave clear answers. His recommendations for tests and treatments were in form of questions and I felt I had a choice in my response. It was an outstanding first visit. The only reason I didn't rate a 10 is that it was the first visit

I told the nurse/assistant that i was adopted and as she was walking out of the room she said we could be cousins.... Don't think that was an appropriate comment BUT overall Dr. Decker is the best doctor i have seen in 10+ years! Very grateful for the recommendation to see him.

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. .
Aug. 4, 2019
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.

Dr. Decker is skilled and a great communicator. Dr. Decker is highly responsive to questions and concerns. I particularly like how effectively He & I are able to use MyChart to manage information exchange.
