For Dr. Heather Ross, testing one’s limits can come in many forms.

“Test Your Limits doesn’t have to be about climbing a mountain. What you do in any given day – things happen, things are thrown at you, challenges come up that test you in different ways. They test your patience, they test your mental capacity, they test your work or your ethic – they test some aspect of your life.”

Dr. Ross’ patients push past limits every day. The following five part series showcases the ways in which her patients test their limits – every day.

“My policy is: I got a new heart, I got a new lease at life – a second chance. So I’ve got to put my heart into everything I do.”

While many of her patients find inspiration in Dr. Ross, she finds just as much inspiration from them.

“I’m quite lucky to be challenged and inspired by my patients and the incredible things that they do every day,” she says.
