About us

Macquarie Street Psychology is a private psychology clinic located in Prahran, Melbourne. Macquarie Street was founded by Dr. Dave Demmer and Dr. Beau Growcott based on their shared interest in men’s mental health. The team at Macquarie Street is passionate about addressing the psychological issues faced by men, as well as by members of the LGBTQIA+ community. 

Founded on the values of Innovation, Community, and Action, Macquarie Street Psychology is focused on supporting mental health at both individual and community levels. Our  therapists take an adaptive, authentic, and creative approach to therapy, and support clients to address various difficulties such as depression, anxiety, stress- and adjustment-related issues, trauma, gender identity, addiction issues, phobias, OCD, issues of low self-esteem/self-worth, relationship issues, and personality disorders, as well as many others.

Dr Dave Demmer and Dr. Beau Growcott also operate Wellington Street Psychology, located in St. Kilda. We have various therapists at both locations. Click here to visit the Wellington Street website.

Want to be part of our team? We want to hear from you. 

Given the current community health concerns we ask all those who visit our clinic to follow these guidelines:

  1. If you have any symptoms consistent with COVID-19, or any flu-like symptoms, please do not attend your appointment in person. Please contact your treating psychologist as soon as possible and they will organise to meet via TeleHealth;

  2. Please ensure you wash and sanitize your hands when entering the premises – hand wash, hand sanitizer, and disposable paper towel are available in the common areas of the practice;

  3. We ask that any friends or family members who may support you to get to your appointment not enter the premises (unless you are under 18 years of age). If you do require a friend or family member to wait with you please let your treating psychologist know prior to the appointment;

  4. Please maintain a 1.5 metre distance from all others in the waiting room (the waiting room is currently configured to support this so please take a seat in the allocated chair positions);

  5. TeleHealth appointments are available and your treating psychologist will discuss this option with you directly.


Our practice receives regular professional cleaning and we will continue to prioritise your health and safety.
