Dr. Abreu is the Center’s Founder and Director. A native of the Dominican Republic, Dr. Abreu obtained his medical degree in 1992 from Pontificia Universidad Catolica Madre y Maestra, located in Santiago, the Dominican Republic. He continued his medical training in an Internal Medicine Residency, followed by a Pulmonary and Critical Care Medicine Fellowship, both at Beth Israel Medical Center in New York. In 2001 he received training in Sleep Medicine at the Sleep Disorders Institute of St. Luke’s-Roosevelt Hospital Center in New York.
Moving to the Rio Grande Valley of Texas in 2002, he joined the Critical Care and Pulmonary Medicine staff at Knapp Medical Center in Weslaco. Noting the inefficiency of referring patients to the few sleep labs that existed in the Valley at the time, Dr. Abreu established his own sleep disorders center in 2002, a one-bed lab housed at Knapp Medical Center. Dr. Abreu’s charismatic enthusiasm for assessment and treatment of sleep complaints/disorders induced his being joined at Knapp Medical Center by a similarly trained physician (Dr. Juan Manuel Ortiz).
This partnership resulted in the establishment of the Pulmonary and Sleep Center of the Valley, a freestanding Center a short distance from Knapp Medical Center. The Center has subsequently evolved into a two-site Center (adding a site in Edinburg in 2009, which moved to McAllen in late 2014), the Weslaco site becoming the Valley’s first accredited full-service sleep center in 2006. Both sites have achieved accreditation from the American Academy of Sleep Medicine for assessment and treatment of the full spectrum of sleep disorders.
Dr. Abreu is Board Certified in Critical Care, Pulmonary, Internal, and Sleep Medicine, the latter by both the American Board of Sleep Medicine and the American Board of Medical Specialties.
He was appointed Chief of Medicine at Knapp Medical Center in 2006. From 2006 to the present time, he has been awarded Hospital Privileges in Critical Care, Pulmonary, and Sleep Medicine at Knapp Medical Center and at Doctors Hospital at Renaissance in Edinburg.
In addition to his heavy clinical load, Dr. Abreu greatly enjoys teaching and research. He has presented his clinical and research work on a variety of medical topics/issues to local lay and professional groups as well as to national professional groups. Dr. Abreu has additionally authored/co-authored several published abstracts and articles in professional journals. While having interest and expertise in all areas of sleep medicine, his primary interest and area of expertise in sleep medicine is assessment and treatment of central sleep apnea and its variants.
Dr. Abreu is married to Rochy Abreu, with whom he has a daughter (Lorena) and a son (Leander). When away from work duties, he relaxes by engaging in family activities, long-distance cycling and running, hiking, travel, and playing tennis and golf.
