  • "Sound advice in difficult times. Acceptable prices when compared with alternatives. Regular contact and updates in clear understandable form."

  • "I would definitely recommend Harrison Brook to other people. My experience in working with our financial advisor was extremely positive. Speed of response and the level of attention to our needs and requests was great. Administration support was flawless."

  • "Excellent customer service all the way through, professional, proactive, patient in answering all my questions, immediate answer to emails, great follow up and communication, deep legal knowledge and legal experience in the field, all of which helped in having my pension transferred in a faster amount of time than normal. I’ve rarely received such swift and excellent customer service before. The whole complex pension transfer experience could have been heavy and stressful, but instead it was the whole opposite."

  • "It's a nerve-wracking thing to entrust your life savings to a person and company you have never met before. Ryan made the process easy. It was calm, I felt in control and was able to asks and get answers to all the questions I had. I am now all set up with my International SIPP and couldn't be happier."
