About Fremont Urgent Care Center

At Fremont Urgent Care Center we believe that serving, caring and healing are why we are here.  Fremont Urgent Care was established in 1984, to make medical care affordable and accessible to the residents in Fremont and surrounding areas. We continue to strive for excellence in healthcare, doing our best so that every patient feels they are receiving individualized medical care. Our clinician team is led by owner and Medical Director, John Giddens, M.D.   Julia Nyquist, MD, and Veronica Caballero, a certified physician assistant are also full time providers. In addition, we have three part time physicians who assist on a weekly basis, so we can offer healthcare to the community seven days a week. 

Our team brings their skill and compassion to people of all ages, from pediatrics to geriatrics.  In addition to offering Urgent Care, we work closely with employers in the area to care for their injured workers.  The complex world of workers’ compensation is not for the inexperienced clinician.  A clinic that understands the administrative complexity of the workers’ compensation system, can make a huge difference for a patient recovering from a work injury.  Fremont Urgent Care also offers physicals and screenings necessary for employment.  

Our X-Ray department is open during all clinic hours, as well as our laboratory and physical exam services. We are here to support the community and businesses seeking a partnership with their occupational medicine clinic. Our commitment to you is that we make your experience at Fremont Urgent Care a positive one.
