Andrea James, Andrew Darwin & Anna McKibbin
“Katie Cohen was beyond amazing when we used Keystone Law to obtain a lease extension. She truly went above and beyond in order to get it through as soon as possible. Katie took all the stress off us and we had total faith in her. She involved us at every stage which obviously removed the anxiety. Katie works so promptly and her communication skills are superb. She is both professional and clearly extremely knowledgeable in her field. I would and have absolutely recommended both Katie and Keystone Law to anyone that needs professional assistance in this area. ”
- Louise
“Katie Cohen super delivered. She was perceptive, sensitive, discerning, made you feel safe and could anticipate what you needed before you asked. If she said that she was ‘on it’, you could trust that she was ‘in your corner’. She knew her job and she did if excellently which makes this experience so much sweeter as nearly 5yrs ago, she and her team could not take on our case because they were at capacity.”
- Private Client
“Very responsive and easy to deal with. We selected Keystone from a list recommended by our surveyor. The selection was based on how quickly they responded to our inquiry and this quick response was a feature of all our dealings with them. Katie has been very easy to deal with and moved the process along very quickly. Great work.”
- Chris Shepherd
“Katie Cohen supported me on a lease extension. Katie was extremely responsive throughout the matter, I received frequent updates and clear guidance and a very efficient service.”
- S. Ayling, client
“I engaged Katie Cohen at Keystone Law to extend the lease on my flat and could not be happier with her work. She was clear, concise and professional throughout the process and extremely quick to respond to any questions that I had. I could not recommend her highly enough and would be more than happy to engage her services again if the need arises.”
- F. Crane, client
“My project involved complex lease negotiations, and a quite difficult client. Katie handled both with expert skill with a welcome sense of humour. A successful mission. I regard her very highly, and will commission her services again without reservation.”
- H. Greenhalgh, client
“Thank goodness for professionals like Katie Cohen. Katie was very reassuring, incredibly efficient and responsive, and got the job done within the timescales required. I would highly recommend Katie.”
