Pediatric Heart Specialists (PHS) was founded in 1983 by Dr. Penn Laird Sr. The original office was located at Northwest Highway and the Tollway. In 2001, Dr. Tracy Laird and Dr. Penn Laird II joined the practice, and the office moved to Medical City Hospital. In 2009, Dr. Amit Verma joined the practice, followed by Holly Tomlin as the practice's first nurse practitioner in 2011. In early 2012, Dr. Michael Day joined the practice, followed by Dr. Christy Glasow and Dr. Shannon Blalock in 2013. In 2015, the practice added Ashley Hanson as its second nurse practitioner and in 2016, Dr. Alan Sing joined on as well.
PHS moved to a new location on Merit Drive in 2018 to accommodate its growth. PHS joined Children’s Health in 2019, introducing our patients to a wealth of resources offered by the nationally ranked Heart Center, including advanced imaging, a team of world class cardiothoracic surgeons, and cardiac specific neurodevelopment services, among many others.
PHS offers outpatient cardiology services in a variety of locations throughout North Texas and East Texas.
PHS welcomed Dr. Andrew Lashus in 2021 and, sadly, said goodbye to Dr. Michael Day.
