Our Philosophy

“Our practice is proud of the personalized healthcare that we provide to our patients. My approach to healthcare is nursing driven as it is important to me that my patients are educated about their health and more importantly, wellness.”- Sharon Larsen, DNP, APRN, FNP-BC

What is CardinaLight Health?

Here at CardinaLight Health, LLC, we have an essential company motto: Healthcare that comes from the heart. This is because we offer a distinctive type of primary health care. Our care is not traditional, but rather personalized to each patient we see.

We are passionate about providing our patients with the information to understand and improve their health. In addition, we form connections that keep our patients coming back year after year.

Sharon Larsen began CardinaLight Health to serve Crystal Lake and surrounding communities. She is passionate about providing patient care that embodies love, faith, and purpose. Above all else, she wants her patients to understand and be able to improve their health.

Sharon is a licensed nurse practitioner with the Full Practice Authority (FPA) in Illinois. That means she can see patients and offer a full range of care, independent of a physician. She is also board-certified in family medicine. Full Practice Authority allows for more efficient and less expensive care — both of which are important to all healthcare seekers!

Our practice is affiliated with area hospitals. Patients are able to have diagnostic tests completed at any of the area health systems and the results will be sent to us. If one of our patients is admitted to a local hospital, they will be seen by the hospital medical staff. All their records are faxed to the office allowing us to follow up with our patients.

Why Choose CardinaLight Health?

There are many reasons why you should choose CardinaLight Health to serve your medical needs. First, we provide more personalized care. We go over your unique medical needs, treating you like a person, not a number.

We also know how important it is to get to know you so that we understand your individual medical needs. This is why we offer longer appointment times, which gives our patients more time with the provider.

During your visit, we will put together an individualized patient treatment plan so you can take part in your health care. When you leave our offices, you’ll have an understanding of your treatment plan, including what lifestyle modifications need to happen to improve your health. You will also be familiar with the medications that are being prescribed to you, how they work and when you need to follow up.

Our provider can work with any other providers to ensure that you always receive the highest quality health care.

We have a small, intimate office setting allowing us to provide a comfortable environment with the ability to focus on our patients more. All our patients are treated as an extension of our own family.

Our care is focused on wellness and preventive care. We can help improve your health instead of providing “reactive care” for chronic health conditions.

You can easily reach us using several methods, including phone, text messaging, and portal messaging.

If you have billing questions, you can ask us directly instead of waiting on hold using an “800” number.

Sharon Larsen has over ten years of nurse practitioner experience in Primary Care. She has more than 30 years of experience in the healthcare field. All of that previous care was spent as a nurse in emergency medicine.

All patient care is genuine and tailored to the patient’s needs. She works to provide each patient the care she would want her own family to receive.  

We offer quick appointments if needed!

Flexible scheduling and telemedicine appointments are available to accommodate your unique needs.

There are many reasons that our patients repeatedly choose us!

Our patients prefer personalized care that is custom-made to their specific needs.

In addition, patients like seeing the same provider each time they come in. It builds trust and understanding. It offers a continuity in care that you do not get at more extensive health facilities.

There is a good reason we have stayed successful for this long. It is because we serve our patients with efficient, personalized care.

Our patients feel comfortable participating in their healthcare and receive quick resolutions to their questions and concerns.

Why “CardinaLight”?

Many believe that when a cardinal appears, an angel is near.  The name of our practice, CardinaLight, was born with this thought in mind.  My father left behind a legacy that is filled with love, faith and purpose and we wanted to honor this in an endeavor I know that he would have completely supported.  Our practice logo is representative of me and my father in a brakeman’s lantern, a lantern my paternal grandfather used throughout his career, and a lantern that was present in our home my entire childhood.  CardinaLight Health, LLC hopes to be a medical practice that will embody that love, faith and purpose.
