Christopher Gozali, DO
Core Faculty
I was born and raised in the western suburbs of Chicago. I attended the University of Illinois Urbana-Champaign for undergrad with a B.S. in Molecular and Cellular Biology and Loyola University Chicago for graduate school where I earned my M.S. in Physiology. After some time spent working at Hines VA Hospital in clinical research, I attended medical school at the University of New England College of Osteopathic Medicine in Biddeford, Maine. It was there I met my wife, Eleanor, and once we finished our time on the East Coast, we decided to return to the Midwest and were fortunate to couples match at MacNeal Family Medicine Residency program, eventually becoming co-chief residents. After the completion of residency, I continued my time here at MacNeal with the Faculty Development Fellowship run by Dr. Foley. After a great fellowship which included the birth of our daughter, I happily accepted a position as core clinical faculty for the MacNeal FMRP to continue working with the amazing faculty and residents.
My professional and clinical interests include preventative care, osteopathic manipulative techniques, medical education and all types of clinic procedures from OMT to shave biopsies. I also oversee our didactic curriculum./p>
Outside of medicine, my interests include comic books, video games, fantasy football, being a fan of Chicago sports (a big source of grief), and enjoying and exploring the wonders of parenthood with our baby daughter Lilah.

Mathew Lo, DO
Core Faculty
I was born and raised in the sunny state of California where I attended the University of California, Merced for my BS in Biological Sciences and met my wonderful wife, Cecilia. I have always felt a strong pull to medicine, but took some time after my undergraduate career to explore other aspects of the medical field. While completing the Pre-Health Professionals Post-Baccalaureate program at California State University, East Bay, I worked at a genetic screening company and later as a behavioral technician for children with autism spectrum disorder. Volunteering at a free clinic in my hometown of Tracy really solidified my role in medicine and wanting to pursue my career as a physician. This is also where my passion for service to the medically underserved first started.
That pursuit and curiosity eventually brought me to Chicagoland, where I attended Chicago College of Osteopathic Medicine. My passion for working with the underserved continued to flourish while rotating through various clinics and hospitals in Chicagoland. I rotated at MacNeal as a student, albeit not with the Family Medicine Team, but fell in love with the patient population. I loved the opportunity to help the Spanish-speaking community while getting to learn more Spanish along the way. I was fortunate to complete my residency here at MacNeal FMRP and served as one of the Chief Residents during my final year of training. I enjoyed my time at MacNeal Family Medicine and working with the amazing patient population so much that I took the opportunity to continue my career with MacNeal by staying on as clinical faculty.
Medically, I enjoy the full spectrum of Family Medicine including prenatal care, office-based procedures and osteopathic-manipulative medicine. During my training I developed an interest in medical education and training, POCUS, EMR optimization and home visits.
Outside of medicine, my wife and I enjoy traveling and trying all of the foods. Chicago is a top food city and we have made a point to take advantage of it. We have traveled through many parts of Central and South America, with plans to travel overseas to Europe soon. Our favorite country so far has been Mexico, where we seem to keep going back to. I am an avid soccer fan, particularly Arsenal FC and Chicago Fire FC. I also enjoy dabbling in amateur photography. We like to spend time outdoors with our dog, Peanut, who is heavily featured on our camera reels next to all our culinary adventures.
