Mercy Comprehensive Care Center


The team of medical professionals at Mercy Comprehensive Care Center seeks to be a community health resource by providing care for all of your non-emergent medical needs in one place. From women care and family medicine services, specialties like podiatry and nutrition counseling, to diagnostic testing, our providers take the time to form one-on-one relationships with each of our patients to ensure that you and your loved ones receive the highest quality care. 


Primary Care – Our primary care physicians are here to provide a constant support system for our patients to lean on. Few things are more important than your health, which we treat by conducting annual physicals, providing care for your non-emergent medical needs, and assessing symptoms for specialist referrals.

Women Care – Whether it's your routine checkup, disease diagnosis and prevention, or providing knowledge and support throughout your pregnancy, we believe in empowering women with the information they need to have full confidence in their own health.

Pediatrics – Pediatricians provide care for children and young adults up to the age of 21. Our trusted physicians focus on ensuring your loved ones' health by treating everything from minor injuries to complex health conditions. We encourage patients to visit our office for annual physicals, sick visits, and preventative healthcare.

Podiatry– Podiatrists are physicians who primarily specialize in the diagnosis and treatment of illnesses and injuries of a patient's feet, though other lower limbs may also be impacted. Our doctors are also highly skilled at recognizing the signs of medical conditions that may first be presented on a patient's foot, such as diabetes or vascular disease.

Nutrition Counseling – Counseling sessions with our expert dietitians provide a way for patients to examine how their lifestyle and diet are reflected in the way they feel. We hold ourselves to the highest standard of patient care by taking the time to understand patient concerns and observing your privacy.

X-Ray – X-ray technology is used to detect fractures or breaks in bones and to locate foreign objects in the body. The images provided by our technicians can inform physicians' decisions about the right way to care for your injury.

Ultrasound – An ultrasound is an effective type of imaging that allows technicians to examine the structures and organs inside of your body. Ultrasound technology bounces sound waves off of body tissue and translates these waves into images.

Blood Testing – Catholic Health laboratory services test and process blood locally, allowing for fast, same-day results. Our locations offer an extensive catalog of blood tests, helpful in diagnosing disease, measuring risk factors, and evaluating a patient's overall health. On the day of your visit, be prepared with a prescription, identification, and insurance information. Make sure to follow any specific instruction from your doctor as well.
