About SDMI

Why sdmi

Our People

We think that It’s What’s Inside That Counts is much more than just a clever tag line. It speaks to who we are as people, what we do, and what we stand for. Everything the SDMI team does is about delivering the best possible experience to our patients.  We know healthcare can be scary. That’s why, when you arrive, we will welcome you with a warm smile to let you know how glad we are to see you; we’ll answer all your questions and concerns and hold your hand during your procedure; and most importantly, we will make you feel like a loved member of the family.

Our Facilities

Abundant with natural light, well-managed and spotlessly clean - we pay attention to the details because we know how important every aspect of your visit is to your overall experience.

Our Technology

Is image really everything? We would argue that, in radiology [and your diagnosis], ACCURACY is everything. That’s why we invest each year in acquiring the latest breakthroughs in imaging technology. Would anything else be good enough when it comes to finding the answers you need? We don’t think so, either.

Our Mission

Deliver an EXCEPTIONAL patient experience and accurate results through compassion and cutting edge technology.

Our Vision

Be the medical imaging provider of choice for every patient and physician, and the employer of choice for our community.


For decades, SDMI has been breaking new ground in the medical imaging industry.

In 1958, Dr. Leon Steinberg moved to Las Vegas to open Sunrise Hospital’s first radiology department in Southern Nevada. Through this experience, he saw a need for a more patient-friendly option for medical imaging and aimed to build such a practice. With Dr. Mark Winkler and his son, Dr. David Steinberg, as his partners, Dr. Leon opened the first SDMI office in 1988. Their standards of excellence in patient care and technology have brought national and international recognition. Today, the commitment to deliver top-notch care wrapped around a positive patient experience has never been stronger. With more than 30 years under their belt, the number one priority in this family-owned business is to make sure that every patient is treated as a VIP.
