Meet Our Staff and Family Doctor in Belvidere, IL

Many people agree that when you have your health, you have everything. You have to take care of your body to stay healthy, and most people go to the doctor if they think they have a serious problem. But when was your last checkup? Medical experts agree that people in generally good health should have a yearly medical examination. A comprehensive check that includes your blood pressure, heart rate, and other health care services, including lab work, could help identify an issue at an early stage.

If you do not already have a doctor, it is best that you find a primary care physician that makes you feel comfortable. You should feel at ease because you need to tell your doctor about any symptoms you’re experiencing. At our health care clinic, we do our best to live up to our practice’s name. We want you to understand that we welcome everyone in your family, and we will provide each of you with personalized care.

Dr. Therese Lucietto-Sieradzki, M.D., provides health care services in Belvidere, IL.

Dr. Therese Lucietto-Sieradzki, M.D.

Dr. Lucietto-Sieradzki spent the first years of her career using skills she gained through her Bachelor of Science in Materials Science Engineering from Northwestern University in 1989. She then followed her passion and graduated from Northwestern University Feinberg School of Medicine in Chicago, IL. She focused on family medicine and completed training at St. Francis Hospital and Ravenswood-Illinois Masonic Hospital in the Chicago area.

As a board-certified family physician, she began caring for under-served patients in 2001. She was inspired to open Your Family Doctor in 2005 to provide high-quality, personalized care.

Dr. Lucietto has practiced throughout the region and is licensed in Illinois, Wisconsin, and Louisiana. She became certified in homeopathic medicine in 2015 as part of her dedication to lifelong learning. 

Dr. Lucietto is dedicated to providing the proper healthcare services to address her patients’ concerns. She never stops seeking solutions and is ready to call on specialists if needed. She has privileges at Swedish American Hospital, OSF Saint Anthony Medical Center, and Beloit Memorial Hospital, and works part-time at Rosecrance substance abuse center. Dr. Lucietto also volunteers as the ring-side doctor for the Patriots Boxing Club.

If you know anything about modern health care services, you know that nurse practitioners and physician assistants now handle many of the duties doctors previously provided. We may give you an appointment with our certified nurse practitioner when you call our clinic. Scheduling you as soon as possible is our goal.

A Clinic That Feels Like Family

A family physician is your confidante, your professional caregiver, and sometimes even your therapist. Their entire career focuses on ensuring their patients feel reassured and confident enough to discuss personal health concerns. There are countless conditions, issues, and problems humans experience, and our family physician is here to help with all of them. If we don’t know the answer, we‘ll refer you to someone who does. Our primary goal is to ensure everyone feels they matter and that their healthcare is our priority. No one leaves our clinic without feeling supported and cared for by every member of our team, from our administration to our physician.

Our support staff is welcoming, understanding, and compassionate. When you need someone to turn to for your health concerns, our clinic is here to answer your questions and ensure you get the treatment you need. Give us a call, and you’ll discover why so many of our patients recommend us to others. We’ll schedule your appointment, make sure we understand your concerns, and get you in to see our family physician as soon as possible. There is nothing we’d rather do than support the healthcare of the people in our community.
