Dr Sam Collins runs Aspire which is all about supporting and developing women as leaders. I did participate in some telephone group coaching sessions with Sam a couple of years ago. The format didn’t work for me but some others loved it and Sam Collins is certainly impressive. They offer a range of courses, events and coaching so you may find something useful.Not cheap, although there are discounts for non profits and for self funding individual women.
Aspire is the UK’s premier executive coaching and development organisation for women. Executive & Life Coaching for Women
