This was our initial visit with Darren Brenner, MD. Our impression is that he is willing to get to the bottom of the symptoms that have tanked our quality of life. We have basically been at a zero for the past year and he took the time to make us feel comfortable and understood today. Our previous experiences elsewhere have not been the case. His knowledge base & experienced team actually give us hope that things can get better. We never felt rushed at all and our current questions have been answered. We are grateful and appreciate his time, care & consideration.

He was on top of my case, which is fairly long and complicated, and he did not leap to any conclusion other than the importance of a series of evaluations before developing a plan. When an X-ray that he ordered that day revealed a serious issue, he had his staff member get me to come back and go directly to the ER. Over 4 days he organized my treatment in at least 4 units (ER, a unit in the Olson building, Intensive Care, and General Medicine.
