Nursing Team


At Family Emergency Room, all our nurses are trained in emergency medicine and have a background in hospital based emergency rooms. We are used to the hustle and bustle of a busy hospital based emergency room. What we enjoy most about Family ER is we can provide life saving measures to trauma, emergent and acute illnesses. We have the ability to provide quality, interactive care for our patients. We can dedicate our time and attention to ensure our patients feel that we truly care about them and their well being. After all, this is what our team got into the medical field for.

Lab & Imaging Team


Our lab diagnostics and imaging team are top notch with years of quality service and experience. We are quick and thorough. We value our patient’s time. Having an on-site imaging center and lab processing allows us to provide immediate results. Our team goes the extra mile to make sure our patients feel comfortable and cared for in a timely manner.
