Clients say of her:
Her judgement is razor sharp. Under immense time pressure and navigating complex rules, she speedily formed her opinion, liaised with hostile opposition, and closed the deal in a smart and flexible manner.
The advice Helen provided me with on my technical international tax issues was unbelievably thorough. It put my mind at rest that she did not leave any stone unturned. HMRC interviews were never stressful as Helen was always completely in control.
