Jacquelin Vaithianathan

Phlebotomist

Jacquelin is our talented phlebotomist here at Spark Health. She handles all things blood and vitamin injection-related. She has been drawn to the medical field since she was a little girl and is currently in school with an interest in pursuing something in labor and delivery or surgery.

Jacquelin has been with Spark for a year and likes to say how rare it is to find a place like this that cares so much about their patients and getting to the root cause of issues. She finds it incredibly rewarding to be a part of the process that helps others get insight into their health.

Outside of Spark she really enjoy being outside in the sunshine, painting, reading and walking by the beach. This year she is hoping to read a new book every month so let her know if you have any good recommendations when you come for a blood draw!
