About Us
Reliance Mobile Diagnostic Services was founded in 2008 with a clear mission: to provide high-quality diagnostic imaging services with the convenience, responsiveness, and compassionate care of a mobile service.
Founded by an experienced sonographer with an extensive background in medical imaging and healthcare, Reliance was built with a strong understanding of what truly matters in diagnostic imaging — quality studies, proper imaging protocols, experienced technologists, patient safety, and dependable service.
That clinical foundation continues to guide everything we do today.
Reliance provides comprehensive mobile diagnostic services, including Ultrasound, Echocardiography, and Digital X-Ray, delivered directly to patients in the comfort of their homes and other care settings. Our team is committed to obtaining high-quality diagnostic studies while treating every patient with professionalism, dignity, and compassion.
Since 2008, Reliance has grown into a trusted mobile diagnostic provider serving physicians, house-call practices, healthcare organizations, facilities, and patients across the communities we serve. As we continue to grow, our commitment remains unchanged: maintaining high standards of clinical quality while providing responsive and reliable service to our healthcare partners and their patients.
Our Commitment
At Reliance, mobile diagnostic imaging is more than a service — it is our clinical specialty.
We believe patients should have access to quality diagnostic imaging regardless of where they receive their care. By combining experienced professionals, modern diagnostic technology, established imaging protocols, and personalized service, we strive to deliver an exceptional experience for both patients and healthcare providers.
