MOTIVATING FACTOR
“I’ve always loved crafting legal arguments and picking apart others’ arguments. MSD is great fit for me because it allows me to work on the research, writing, oral advocacy, and strategic aspects of a wide variety of complex cases with committed people who share my appreciation for the importance of paying attention to every detail, anticipating your opponents’ moves, and leaving no stone unturned in serving our clients.”
CREATING VICTORY
“Figuring out the law governing a case is like a mystery waiting to be solved. It calls upon all of a lawyer’s analytical skills and investigative instincts. I’ve won arguments because I was obsessed with reading and re-reading the language of a contract, statute, or case and noticed a word, phrase, sentence, or even a punctuation mark that no one else seemed to notice and was able to make something of it. I’m fortunate to work among people who share this obsession.”

How do I choose a lawyer?
Consider the following:
- Comfort Level – Are you comfortable telling the lawyer personal information? Does the lawyer seem interested in solving your problem?
- Credentials – How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?
- Cost – How are the lawyer's fees structured — hourly or flat fee? Can the lawyer estimate the cost of your case?
- City – Is the lawyer's office conveniently located?
Not sure what questions to ask a lawyer?
Here are a few to get you started:
- How long have you been in practice?
- How many cases like mine have you handled?
- How often do you settle cases out of court?
- What are your fees and costs?
- What are the next steps?
Want to check lawyer discipline?
It is always a good idea to research your lawyer prior to hiring. Every state has a disciplinary organization that monitors attorneys, their licenses, and consumer complaints. By researching lawyer discipline you can:
- Ensure the attorney is currently licensed to practice in your state
- Gain an understanding of his or her historical disciplinary record, if any.
- Determine the seriousness of complaints/issues which could range from late bar fees to more serious issues requiring disciplinary action.
