Dr Koncilja took time to cover multiple issues and I did not feel like I was being rushed. I am very happy that he is my PCP.

She has a very strong personality. She seemed very hurried, computer focused. I'm guessing bc too many pts, too little time. She did have helpful plan and suggestions.

I cannot sing the praises of Dr Konscilja enough! I am a HCW, & he surpasses the high bar I have set. His knowledge base just amazes me. He's jack-of-all trades and master of many. He really seems to genuinely care. He is looking steps ahead, and I love it! He's not just dealing with x. He looks at working up x, but addressing y & z in anticipation. He collaborated with me about my care vs telling me to do something and moving on. You need more providers like him.

You have a great doctor here and he pays attention to his Patients questions I'm hard of hearing and he did a nice job of trying to understand our issues. I'm extremely hard of hearing would be a better way to put it.

We love this doctor. He has been very helpful.

Great care givers are in great demand. That means scrambling to book appointments when they open. NOT a complaint, as Dr. Koncilja & Staff bend over backwards to see us when we need to be seen. They are great managing an ever-increasing patient load. We'll keep scrambling because they are so good! Give them more help!

Dr Koncilja is a wonderful, thoughtful and compassionate provider who is both optimistic and realistic at the same time.
- 5 out of 5 starsReviewed on 5/19/2025
Dr. Koncilja's sensitivity and clarity are unmatched in my considerable experience as a patient. It's hard to believe a doctor this young speaks the language of a 70-year-old.
