Modern Technology School Admissions

We Make the Admissions Process Simple & Love Answering Your Questions! Let Us Help You Pave a Path to Your Success!

At Modern Technology School, we work hard to make enrolling in an X-Ray Technician, Ultrasound / Vascular Technologist, or Medical Assistant Program as simple as possible. We strive to streamline our admissions process and it all starts with ensuring students have a good understanding of the value they’re receiving from their education. We want there to be a great fit on both ends, and that our courses align with your educational & career goals.

Oscar recently came aboard as our Admissions Advisor at Modern Technology School in 2021, and brings many years of experience working with college-level students. Oscar is friendly, easy to relate to,  never-pushy, and is dedicated to working with our students while they are registering, in order to ensure they have all their bases covered.

When speaking to Oscar, you’ll quickly learn that he’s straightforward, honest, and loves to answer student’s questions. While other schools’ admissions reps are focused solely on placing students in the program, You’ll find that Oscar takes the time to understand each student’s goals, in order to ensure that they are making an educated decision about their future, first.

Another great bit of feedback we’ve received, is that Oscar is helpful in making sure that the admissions process is laid-out as simply as possible. He knows the ins-and-outs of our X-Ray Technician, Ultrasound / Vascular Technology and Medical Assistant programs, and is happy to share his knowledge with students looking at these careers for the first time, or with those who are considering changing careers and diving into Diagnostic Healthcare. Oscar is available to meet with incoming students in-person from Monday through Friday, and can also be reached by phone.

He can also answer many questions about our programs and admissions process by phone. He likes to remain accessible to students in order to ensure they are comfortable at their new home away from home.
