5.0 star star star star starA good & open communication between a Primary Care Physician (PCP) & the patient are necessary to have a great visit, proper diagnosis & treatment. I feel Dr. Peck & I have that relationship. I highly recommend Dr. Peck to anyone who needs a good PCP & internist.

5.0 star star star star starDr. Peck was terrific! She was caring, and she spent the necessary time to fully analyze my condition. I truly appreciated the fact that there was no rush in her approach. Of course, she also seemed highly qualified and extremely knowledgeable.

5.0 star star star star starShe is very thorough, kind, caring and takes time to answer all questions. She never makes me feel rushed. I really feel she cares about me. Even though I may not be her most challenging case she still makes sure I feel extremely cared for.

5.0 star star star star starDr Peck does not rush you when she is meeting with you. She hears what you have to say and makes recommendations that appear appropriate. We are still new to each other and are getting to know each other so there's still a little awkwardness. I also have a lot of specialists I work with so it's trying to find the right balance Between the primary care and the specialist.

5.0 star star star star starDr. Peck has been my doctor for about 25 years now and I would never consider anyone else. She is the most caring professional and dedicates plenty of time to understand what is affecting the person, emotionally and physically. She is wonderful and I can't say enough good things about her. Just the best!!
Disclosures
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.
