About Us

At PsyFlex, we don’t just deliver programs—we create sustainable change. By integrating cutting-edge research and expert knowledge, we help organisations reduce psychosocial risks and build environments where everyone can thrive.

PsyFlex is led by Dr. Natasha Lazareski, a medical doctor with 30 years of experience in organisational health, psychosocial risk management, and coaching. Natasha has extensive experience in medical and injury management roles across workers’ compensation, personal insurance, and both public and corporate sectors. Natasha and her team can help you deal with a wide range of challenges, from effectively managing the psychosocial risks of your workplace to overcoming personal barriers, and building your coaching skills.

Recently, Natasha has conducted extensive research on menopause and collaborated with leaders in women’s health to create a science-based, accessible women’s health program. This includes our menopause transition program , along with coaching for women, health practitioners, HR professionals, and leaders.

Our Purpose

Our purpose is to empower people to efficiently deal with everyday life challenges, and to help employers build safe, healthy and supportive work environments.

PsyFlex isn’t just a business—it’s my passion, born from a lifetime of overcoming challenges. After studying medicine in former Yugoslavia, I lived through the devastation of civil war, leaving my family,  starting over in a foreign country, and having to rebuild my career and my life. But throughout all these challenges, I held onto my commitment to make a positive difference in people’s lives.

Work defines much of our lives, and I’ve seen firsthand how it can either provide meaning and fulfilment or become a source of great stress and suffering.  My experiences have shaped my mission: to help others deal with their challenges and create healthy workplaces.

PsyFlex is a labour of love, grounded in science, practical and adaptable for any environment. Whether you’re looking to enhance your health,  improve workplace wellbeing, deal with everyday challenges, or manage menopause, we’re here to help.

Join us in creating a healthier, more fulfilling future.

Dr Russ Harris – Affiliated partner

Russ Harris, author of the million-copy-bestseller, The Happiness Trap, (as well as nine other books), is a world-renowned trainer of Acceptance & Commitment Therapy (ACT), and advisor to the World Health Organisation.

Russ’s background is in medicine. As a GP he became increasingly interested in the psychological aspects of health and wellbeing, and increasingly disenchanted with writing prescriptions. Ultimately this interest led to a total career change. He now works in two different, yet complementary roles – as a therapist and as a coach.
Since 2005, Russ has run over 600 two-day workshops and provided ACT training for over 40,000 health professionals, including therapists, coaches, counsellors, doctors, and psychologists. In 2015 he created an ACT protocol for the World Health Organisation to use in refugee camps around the globe. In 2020, the WHO published their first research on this protocol, which showed significant reductions in PTSD and depression that from just 10 hours of ACT.

He has authored three ACT textbooks (ACT Made Simple, Getting Unstuck in ACT, ACT Questions & Answers), and four ACT-based self-help books (The Happiness Trap, The Reality Slap, The Confidence Gap and ACT with Love).

He has also co-authored two self-help books (The Weight Escape and The Happiness Trap Pocketbook). The Happiness Trap is the best-selling ACT book in the world, translated into over 30 languages.
