Brock has given us very detailed and scientific understanding about why we behave and react in certain ways. We have been given clear suggestions and alternatives to previous behaviours that have been harmful to our relationship. Clear and practical suggestions as to how to choose different habits has allowed us to significantly reduce negative patterns in our relationship. We would thoroughly recommend Brock as an outstanding specialist.
Dr Chisholm allowed me to open up and he gave me tips on how to practice change in my life. He was amazing, I felt like his advice will be used long afterwards.
He helped me not to feel guilty (for losing a loved one).
We put a plan in place to start to work on my fears that have kept me paralysed all these years.
Brock really helped me set/take some small steps for having a more enjoyable life.
We consolidated what I felt I know, but enhanced strategies for better growth.
You treated my wife for PTSD some years ago and she made a full recovery and with your support she prosecuted her perpetrator. She has been well for many years but last month she was involved in a car crash and was physically unhurt. However she has been suffering terrible anxiety and is having regular flash backs. The only person that was ever able to help her was yourself.
I have had the pleasure of working with Brock for the last several years. He has a warm and genuine approach helping people who are experiencing some of the most difficult events in life; such as terrorism, sexual and physical assault, occupational trauma, childhood trauma and loss. I know that with excellence Brock helps people to make sense of stressful and traumatic events and how they are impacting on emotions and behaviours. I have seen Brock work collaboratively with his clients to relieve suffering and support them to make changes that improve their quality of life. Brock is a well-respected clinical psychologist who many professionals draw on for clinical advice. I highly recommended him.
