Hospital Welcomes New Leaders


 Don Dionisi
Surgical Director

Yvonne Nickels
PCU/ICU Manager 

Heather Morehouse
Registration Director

SAN MARCOS, TX – In recent weeks, Central Texas Medical Center (CTMC) has filled several important leadership positions as part of its ongoing efforts to improve and enhance the patient experience.

Heather Morehouse joins the CTMC family as the director of registration. She comes to CTMC from Christus Santa Rosa Hospital in San Antonio and said she enjoys working with CTMC’s electronic medical records (EMR) system, something the hospital has been ahead of the curve on since becoming the region’s only fully-integrated EMR in 2006.


“CTMC is up-to-date and on the ball with their initiatives,” she said. “I’m looking forward to this opportunity to grow.”


Morehouse completed 6 years of active duty in the U.S. Navy where she worked in the medical field managing medical records and completed other medical tasks. For 8 years, she served in the Reserves. She has a Bachelor of Science from Texas State University in Health Information Management. In her spare time, Morehouse enjoys taking weekend trips to the coast with her husband and 6-year-old son and listening to country music. Her family is also active in the Austin Boxer Rescue.


Don Dionisi was named CTMC’s surgical director earlier this month. Before coming to CTMC, Dionisi spent five years as the director of surgical services for Valley Baptist Health System in The Valley. Prior to that, he was in a director role in the Dallas-Fort Worth area. He graduated from the University of Texas at Arlington with a degree in nursing and went on to obtain his master’s degree in human relations and management from Abilene Christian University. He served in the U.S. Air Force as a scrub tech.


Dionisi has been in health care for more than 30 years and said he is impressed with CTMC’s cutting-edge technology, the good reputations of the doctors and excellent patient outcomes. He also appreciates the hospital’s mission to extend the healing ministry of Christ.


“I’ve worked for faith-based organizations before, and there’s just a whole different attitude and you take care of your patients the way they need to be taken care of whether a person has means or doesn’t have means,” he said.


In his spare time, Dionisi likes spending time with his dogs, gardening and exploring his interest in agriculture.


Yvonne Nickels recently became the clinical nurse manager for CTMC’s PCU/ICU departments. For the past 14 years, she was employed by the Methodist Health System. Nickels worked in the ICU at Northeast Methodist Hospital in San Antonio for 12 years, where she started as a staff nurse and worked her way up to assistant director and eventually became director. For the past year-and-a-half, she was a supervisor in their centralized staffing office.


Nickels is originally from Houston and received her bachelor of science in psychology from the University of Houston. She went on to earn a nursing degree from Antelope Valley College in California and later got a graduate degree in health education/health care administration from Texas State University.


“I am very happy to be here,” Nickels shared, noting that health care has been her career choice since childhood. Nickels is married and has three grown daughters. In her spare time, she loves to travel and read.


Our new leaders join the CTMC team with great passion, knowledge and experience of the industry and will truly be a positive attribute to our hospital and community. As of the close of the second quarter in 2012, CTMC was in the 67th percentile for its overall hospital rating.


About CTMC
The hospital, which originated in 1923 as Hays County Soldiers, Sailors and Marines Memorial Hospital, was restructured in 1960. The present facility was opened at its current Wonder World Drive location in 1983. The CTMC staff of more than 700 employees works with more than 220 active and consulting physicians to provide quality services to patients and their families. In addition, over 200 community members and interns from area educational institutions volunteer their services to the hospital. In 2010 and again in 2011,  CTMC was named The Best Hospital in Hays County.  In addition, CTMC added a certified Chest Pain Center to its ER capabilities in 2011. In 2012, CTMC became the first operating room along the IH-35 corridor between Austin and San Antonio to be equipped with a da Vinci robotic-assisted surgery suite.


CTMC is a member of the Adventist Health System (AHS), a not-for-profit healthcare organization that emphasizes Christ at the center of care. Founded in 1973, AHS  has quickly grown to become the largest not-for-profit Protestant healthcare provider in the nation. Today, AHS  supports 43 hospitals and employs 55,000 individuals.
