The success of any law firm is dependent on the talent and professionalism of its lawyers and support staff. That is why we are committed to investing in the training and professional development of our trainee solicitors.
We are looking for enthusiastic and talented graduates from all backgrounds and cultures who share our commitment to excellence, want to be part of the continued growth of our London office, and want to become part of the next generation of leaders at our firm.
Providing our clients with excellent service is our number-one priority. Our lawyers need to be commercially minded and approachable, and be able to work with our clients as part of a team on complex and often high-profile legal issues. If you feel you can meet this challenge and want to work at an inclusive firm with a long tradition of pro bono and community support, we would like to hear from you.
