Siskinds is by far the best law firm in London. I contacted them concerning an estate matter. John Morrissey and his assistant Reenya Koshaba, were there every step of the way. They were detail orientated and I was kept up to date throughout. Most importantly though, he effectively solved our problem. John's performance (and team) was above and beyond expectation. I couldn't have asked for more. - M.D.

They’re very responsible, honest and knowledgeable people who’ll provide you with first class service. - M.K.
