Chaffetz Lindsey is a unique firm as it is a boutique, with advantages which a boutique firm can offer in terms of arrangements, but which is still fully capable to provide excellent legal representation with an experienced team of lawyers. We particularly appreciate the partners’ involvement in the case.

We work with James Hosking and Yasmine Lahlou. Both are excellent and smart lawyers who can effectively advise us at each stage of the case. The written pleadings were concise and clear. They kept up with internal deadlines and delivered internal drafts on time. They are highly involved in the case, easily approachable, and flexible to our needs.
