Dont let anyone get you down about going to St. Thomas. I have been practicing law for over 26 years, have been in my own firm for the last 20 years. I have two full time associates. Successful lawyers are those that 1) Prepare 2)Put in the time to learn their area of law 3) put in the extra effort to attend to their client's needs.
You can be highly successful as a grad from a fourth tier school. I have represented clients who have graduated from elite law schools that can not practice law, period.
Just dig hard. Dig harder than the other guy. You may wind up in your own firm.You may struggle. Just keep at it. Get involved with bar associations. Write articles.
If you work your heart out for clients, they will will notice, as will opposing attorneys.
Is it hard? Hell yes but it is there for you just don't give up and start networking now, while in law school.
