Jennifer McGrath

Jennifer has worked at WellMax well over ten years. She is meticulous and almost obsess­ively committed to providing the highest quality of personalized care. She manages our overall process of patient care, and leads our internal meetings. She is usually the first one here and the last to leave. She insures that all follow up care plans are completed, and makes certain that your Personal Health Portfolio™ is “buttoned up.”

Jennifer also does lots of hands-on patient care. She is licensed to perform the DEXA bone density and body composition studies. She administers cognitive tests, and performs cardiac treadmills, V02max, and many other tests.

She arrived in the desert here from Beaverton, Oregon, which she liked, but she believes is too cold and rainy there for full time living. She likes it better here (with us!).
