Nancy J. Laste DVM, DACVIM (Cardiology), Director of Medical Services

Dr. Laste is a board-certified cardiologist who has been with Angell since 1992. Although her primary practice is focused on medical treatment of cardiac diseases in domestic animals (primarily dogs and cats), she is active in interventional cardiology — cardiac catheterization, pacemaker implantation and cardiac surgery. In 1998, Dr. Laste started the thorascopic surgery program, which has successfully treated more than 100 patients with minimally invasive techniques, avoiding the need for open-chest surgery.

Julia Lindholm, DVM

Born at Lowell General, Julia took a very roundabout way to find herself at Angell. She moved to Georgia when she was six and later to North Carolina. She lived in multiple cities in Texas, including College Station where she attended veterinary school at Texas A&M University. A rotating medicine and surgery internship in Indiana was followed by a cardiology internship in Ohio. Finally circling back to the beautiful city of Boston for her cardiology residency. She couldn’t be happier. Her passion, outside of cardiology, is in horses. She rode hunters and jumpers professionally for a short time before attending veterinary school. Her quaint Boston apartment doesn’t suite a horse very well so her after work animal fix is two tuxedo Manx boys. Coming home to specialize in cardiology is quite simply a dream come true for Julia.
