Who We Are

Vigilias was founded by physicians hoping to bridge the provider gap between urban and rural areas using telemedicine. Our providers trained in Internal Medicine, Pediatrics, Family Medicine, and a variety of specialties. All are board-certified or board-eligible, and have experience working in most settings, from tertiary referral centers to small hospitals, as well as the emergency room, urgent care, and outpatient clinics. Several of us live in or have close ties to Kansas.

Some of our doctors worked in rural communities in the past, while others have never seen a hay bale in person. Regardless of past experience however, all of us are dedicated to the core idea that rural health matters, and that the time has come to use modern communication technology to significantly expand the capacity of rural hospitals and providers to offer their patients local access to care that once required a long trip to a large city.

Marketing Director

Charles “Chuck” Coffey, MD, MPH, MBA


Undergraduate: University of Kansas

Medical School: University of Kansas

MPH: University of Kansas

MBA: University of Kansas

Residency: University of Kansas-Wichita, Internal Medicine/Pediatrics

Bio: Chuck was born and raised in Kansas. After college he moved to Boston and was involved in a medical software start-up before deciding that what he really needed was more education. He decided the best way to fragment his medical experience was to take a two year hiatus in the middle of medical school to study business and public health. Chuck currently needs only a JD to complete the alphabet soup quadfecta. Chuck’s roots are in rural Kansas, which makes Vigilias’ mission personal for him.

Personnel Director

Aaron Chen, DO


Undergraduate: University of Texas-Austin

Medical School: University of North Texas Health Science Center

Residency: University of Texas Health Science Center at San Antonio (UTHSCSA), Internal Medicine

Bio: Aaron was born in China, and raised in Texas. After college Aaron spent time working on EMR integration well before the need for it was as pressing as it is now. Aaron is a boarded Internist, and works as a hospitalist in northern Florida, but still trots out his Hook ’em Horns as needed. Aaron has extensive experience with credentialing, and handles privacy issues and new provider onboarding.


Elisha Yaghmai, MD, MPH&TM


Undergraduate: Harvard University

Medical School: University of Texas Southwestern Medical School at Dallas (UTSW)

Masters of Public Health and Tropical Medicine: Tulane University School of Public Health and Tropical Medicine

Residency: University of Kansas-Wichita, Internal Medicine/Pediatrics (Chief Resident)

Bio: Californian by birth, and peripatetic by nature, Elisha has lived in every major region of the United States, and logged time in Africa and Asia. He went into medicine to change the world, but found medicine changed him instead. Vigilias is his way of fighting back. Elisha is double-boarded in Internal Medicine and Pediatrics, and has worked in both rural Kansas and multi-hospital, tertiary referral centers. Elisha has experience as an adult and pediatric hospitalist, urgent care physician, emergency medicine doctor, and rural primary care provider – all part of his informal master plan to learn as much as possible about as much as possible. Elisha believes telemedicine has the power to fundamentally change healthcare delivery for the better.

Vice President and Chief Technical Officer

Patrick Zana Desgranges (“Zana”), MD, PhD


Undergraduate: Massachusetts Institute of Technology

Medical School: Tufts University

PhD: Tufts University, Immunology

Residency: University of Washington

Bio: Zana grew up in Côte d’Ivoire (Ivory Coast), and studied mechanical engineering before completing his medical degree and PhD. He is board certified in Internal Medicine, and has worked as a hospitalist since 2010. Zana co-founded Vigilias in 2014, and has used that as an excuse to let his inner techie run wild. If a telemedicine tool exists, odds are Zana has already tested it, or will soon. When not taking care of patients, or tinkering away in his telemedicine lab, Zana loves to hang out with his wife and two daughters, visit family, do home improvement projects, watch soccer and football, travel, cook, and listen to music.
