Partner-Like Qualities®

The path to becoming a Partner in a professional services firm is steeped in mysticism. Sometimes you only find out what you are up for on the day you are admitted. Leaders of practises strive to identify and nurture the next generation of talent and are looking for those intangible qualities over and above subject matter expertise.

Specifically developed for leaders working in professional services, Partner-Like Qualities® is our unique tool developed in conjunction with our business partner Saville Consulting to help individuals and practise leaders understand the strengths and development areas of existing and aspiring Partners.

"His style is flexible, subtle and engaging.”

"Thank you very much for your assistance this week. From my perspective the workshop was a great success and an important "first step". I have only received positive feedback. In fact, one of our partners (with 40 years experience in professional services) told me it was the best program of this type he has ever been to.”

"Firstly, many thanks for your time last week, I appreciated the candour with which I can speak with you both. I believe the opportunity to work with you will certainly help with this somewhat unique situation and in my own personal development.”

"Again thanks for your fantastic expertise in this endeavour, I doubt very much that we would have achieved so much quality material in such a short time without your input and tremendous ability to not only hear words but understand meanings."

"I had my last session with Jack Crumlin today as part of the DAP on-boarding. I can’t tell you how helpful he has been to me as I have learnt to navigate EY. He has been superb in making me aware of, and focusing my development needs and then providing great frameworks to help me move forward. And I have loved his pragmatic insight on how this place really works.

Not sure how much we pay him, but it’s been invaluable for me. Thank you"
