Ernest Hymel, MD, PhD, MBA

Board Certified
Radiation Oncology

Dr. Ernest Hymel is a Radiation Oncologist with the Baptist Cancer Network at Baptist Hospitals of Southeast Texas. He serves as the Chief Medical Officer for the Oncology Program as well as the President of the Medical Staff at Baptist Hospital.

Dr. Hymel completed his Radiation Oncology training at the University of North Carolina in Chapel Hill in 2005 before moving to Beaumont with his wife, Amy. Despite his administrative duties, Dr. Hymel’s favorite place to be is in the clinic where he has the privilege of working with patients during a difficult time in their lives. His approach to patient care is simple… for every patient he asks himself, “what would I recommend to my wife, or my dad, or my best friend?” As part of his commitment to maintaining high quality care to the community, Dr. Hymel has led the Baptist Cancer Network to maintain accreditation with the Commission On Cancer (COC) and National Accreditation Program for Breast Centers (NAPBC), and has recently added accreditation of the Radiation Oncology Program with ASTRO Accreditation Program for Excellence (APEx).

When not in clinic, Dr. Hymel and his wife work in animal rescue, from dogs to cats and even donkeys!


Andrew Goolsby

Staff Chaplain

Andrew Goolsby is a staff Chaplain at Baptist Hospital, where he helps patients and their families to connect with the spiritual resources they need while undergoing tests, treatment, and follow-up care within the Baptist Cancer Network. He actively engages patients and family members by providing a listening ear as they express their challenges, uncertainties and concerns. He also helps patients to execute advanced directives.

Andrew met the requirements to become a healthcare chaplain before working at Baptist Hospitals of Southeast Texas. After completing his Undergraduate degree at Lamar University and his Master’s degree at Southwestern Baptist Theological Seminary, he continued his training by finishing a year of residency in Clinical Pastoral Education in Austin, Texas. As a resident Chaplain, he served in the Ascension Seton system of hospitals. While there, he provided pastoral care for the patients on the COVID, Medical-Surgical and Oncology floors of the hospital, along with seeing patients in the outpatient Cardiac Rehabilitation Clinic.  Within the Baptist Cancer Network, Andrew journeys with patients as they cope with the spiritual and emotional milestones that come up along the way. He is there daily to provide a loving presence as they endure the rigors of cancer treatments.

Andrew grew up in Southeast Texas, which provides him a connection to the people in the area. He is married to Lauren and they have a son named Theodore. Andrew enjoys watching his favorite sports teams: The University of Alabama athletics and the Manchester United Football Club (an English soccer team). He is also a movies enthusiast and loves to listen to a wide range of music, especially the films and songs that make him feel nostalgic.  Andrew also enjoys laughter and is a firm believer that you can’t take yourself too seriously.


Telice Terro (RN)

Oncology Certified

Telice Terro is an Oncology Certified Registered Nurse. She has 21 years of experience in nursing with nearly all 21 years dedicated to oncology care and 8 of those years working in research. She is also certified in Chemotherapy/Biotherapy Administration. She is the Clinical Research Manager at the Baptist Cancer Center and on the main campus of Baptist Hospitals of Southeast Texas, which means that she is responsible for clinical research involving patients. In this role her job is to educate patients and staff on available research opportunities at our facility, as well as ensuring clinical research studies are carried out within regulatory compliance and advocating for the rights and welfare of patients interested and enrolled in studies at our facility. 

Telice is passionate about her role of connecting patients to research opportunities with the goal to improve healthcare outcomes. She feels this role is important and necessary to healthcare to gain necessary knowledge to help treat patients now and in the future. It is important for patients interested and enrolled in studies to know their decision to participate is their decision and 100% voluntary throughout the entire study. 

Telice entered nursing school with the desire to work in the field of oncology. Although she did not have a cancer diagnosis, she was a patient at MD Anderson for 10 years from the age of 8 to 18. This experience, along with having several family members having a cancer diagnosis, showed her what her purpose was. Immediately after graduating nursing school, she was able to work in inpatient in oncology, followed by outpatient cancer care, oncology screening, then research. Her current role in research was encouraged by the medical oncologists where she began her work as a research nurse/clinical research coordinator. She enjoys working in research – most importantly to make the patients feel comfortable with their decisions to participate in studies and to be able to offer data to research sponsors with the goal of improving healthcare. 

Outside of work Telice is the mother of a 10-year-old who keeps her busy with dance and basketball. She volunteers with her church, working as the church nurse for kid’s summer camp. She has always had a passion for running, but mostly recently her busy schedule has thwarted her efforts. However, she is looking forward to enjoying that hobby again, as she has joined her church’s running group, “Be Fit for Him”.

Matthew Knowles, RT(R)(T)

Director Radiation Therapy

My name is Matthew Knowles, and I am the Regional Director of Radiation Therapy with the Baptist Cancer Network. I started my career in healthcare in 1999 when I attended the Baptist Hospital School of Radiological Sciences program. After graduating, I gained interest in Radiation Therapy and attended The University of Texas MD Anderson Radiation therapy program. Upon completion of my studies there, I stayed and worked at MD Anderson for a year before returning to Baptist Hospital in 2003. Baptist has always been a home to me, and I have enjoyed being able to serve patients right here in my community.

Patient care is my number one priority, and the most effective way I can do that is to ensure our patients have the best possible experience while undergoing radiation therapy. I try to instill empathy and compassion into all of my employees, who in turn touch the lives of our patients every day.

When not working, I enjoy wood working, fishing and hunting and of course, family time. 

Please email me at matthew.knowles@bhset.net or reach me by phone at 409-981-5510.
