He made me feel like I was able to understand what he was doing with ease. It seems as he has a great grasp on his work and how to make recovery easy with the work he does. I had an hour and a half procedure done, was able to go home same day and felt pretty much back to normal within two weeks. He explained things so anyone can understand the procedure that is being done. Excellent doctor and a seemingly excellent person.

Dr. Leitzen belongs to a very small group, of very talented Doctors, who go way above and beyond the call of duty, each and every day. It's actually the hallmark of Lake Forest / Northwestern to be quite frank. The bar, the standard, the attained goal of NM, continues under the kindness, of Dr. Leitzen! You will understand, you will comprehend, you'll be so thankful, after Doctor Leitzen becomes, one of your own Doctors. Thank you Doctor Leitzen for being you, and doing your very best, for all of us.

Disclosures

Keith P. Leitzen, MD reported no external professional relationships for calendar year 2024.

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care. These relationships are important in achieving scientific breakthroughs and in establishing the effectiveness and safety of promising new therapies. In order to assure objectivity in clinical research and patient care, the Northwestern University Feinberg School of Medicine (Feinberg), Northwestern Memorial HealthCare, Children's Hospital of Chicago Medical Center, and the Shirley Ryan AbilityLab have adopted integrity policies that require research and clinical faculty (in full-time, part-time, and unpaid/voluntary categories) to report compensated and uncompensated external industry relationships. Patients are encouraged to discuss these disclosures with their physician as well as to inquire as to how these relationships are overseen by Feinberg.
