professionalism/lawyer's office

Hi everybody!

What do you think about this sentence? Would you change something?

1. All the information enclosed in this offer will deepen your trust in professionalism of (the name of the company) lawyer's office, John Smith limited partnership.

I'm thinking about the word "professionalism," maybe "professional management" (of the company)?

How about the name of the company, should it be before "lawyer's office" or after it, i.e. Green Apple lawyer's office or lawyer's office Green Apple?

Thanks!
