Our Vision.

Chronic illnesses like heart disease, stroke, and cancer remain the leading causes of death around the world—even as medical knowledge continues to grow. Rates of obesity are rising. Stress, screen time, and social isolation have quietly reshaped our daily lives. And despite being more connected than ever, many of us feel more unwell, more anxious, and more disconnected than before.

Lifestyle Medical Services was founded in response to this reality.

Our approach combines Internal Medicine with a strong focus on lifestyle and prevention. We look beyond individual symptoms to understand your overall health, identify risks early, and help you manage existing conditions while making practical lifestyle changes that support your long-term health.

Every visit, every plan is guided by evidence, compassion, and your goals. Our founder brings 20 years of experience in internal medicine to a model that goes beyond prescriptions.

This is not just treatment. It’s transformation.

Get In Touch.

Finding the right doctor matters.
At your first consultation, we’ll take the time to understand what you’re hoping for, explore what’s realistic, and start building a plan that supports your long-term health.

Dr. Petra Crookendale is a Consultant Internist and Fellow of the American College of Physicians with extensive experience in adult medicine. Her approach combines careful medical assessment and management with a strong emphasis on prevention and practical lifestyle change.

Beyond her clinical practice, Dr. Crookendale is actively involved in medical education through teaching and tutoring, and is the creator of Know Thy Health, an initiative that brings practical health education to workplaces and the wider community.

Outside of work, she leads an active, full life. Dr. Crookendale enjoys going to the gym, playing golf, spending time with friends and trying to keep up with her two beloved dogs—a determined Doberman and a pernickety Pitbull. She also follows a plant-based diet, which she credits, at least in part, for her youthful looks. 😉

For Dr. Crookendale, it all comes back to a life well lived—doing work she finds meaningful, staying curious and making time for the people and things she enjoys.

Miss Ashida Foster

Ashida is often the first friendly face (or voice) you'll encounter at Lifestyle Medical Services. As our Client Care Coordinator, she keeps the many details behind your visit organised, from appointments and enquiries to referrals and follow-up.

Known for her warm manner and calm approach, Ashida has a knack for helping things feel a little easier, especially when patients aren't quite sure what they need or where to start.

Outside the office, family is an important part of Ashida's life. She is incredibly supportive to her family and is often on the sidelines cheering on her daughter at sporting events.

Whether at work or with family, Ashida brings the same supportive spirit to the people around her.
