The Psych Professionals was founded by our Clinical Director, Gerda Muller in 2007, whilst on maternity leave with her second child.

The practice grew with leaps and bounds and before we knew it, we had a fully booked group private practice in Loganholme, Brisbane.

To meet community demand, Gerda then opened up a sister practice in 2011, located in the suburb of Capalaba, in Brisbane’s bayside.

Always anticipating market trends and being an advocate for making mental health support available to each and every Australian, Gerda founded the online arm of the practice, Your Psych Online in 2013 – recently rebranded as Source Health.

The purpose of Source Health is to make mental health support accessible to regional, rural and remote communities, as well as anyone else whom for any reason whatsoever can’t access mental health support in person.

It has and continues to be Gerda’s life mission to help more people in better ways and today this includes her role as Founder & Director of Private Practice Success Australia, where Gerda provides Business Coaching & Mentoring to Allied Health & Mental Health Professionals wanting to start, build, expand and scale their private practice.

In addition, removing the stigma around mental health is at the core of everything Gerda does and it continues to be the driving force behind our continued growth and expansion.
