Video Transcript

One of the most important things about practicing law and being an attorney is the fact that I get to continue a legacy that was started by my father.

I was very fortunate in that my father had a practice, and when I started out as an attorney, I worked for a big corporate firm in New York City for a year.

I learned everything in my life I did not want to do.

And I always share with young attorneys and young people in general that it’s equally as important to learn what you don’t want to do as what you do want to do.

And when I left that firm, I was going to get out of the law completely.

I loved working with kids. I thought I’d get into camping and working with children who go to camp.

My father was kind enough to sit down with me and say, “You know what? You’ve put in all of this time. Before you leave the law completely, why don’t we work together for a year?”

We were best, best friends. We didn’t want to jeopardize our relationship.

So we said if after a year we’re not happy, we’ll split and everything will be fine.

We were together for 17 amazing years, where he was kind enough to allow me to second chair him to sit in on his trials and learn.

And then he was kind enough to second chair me when I started my trial work.

And that situation and that scenario put me in a place where I got to not only learn things, but learn how to enjoy what I’m doing.

So I always tell people when they ask what I do, I say I’m a happy attorney because I actually still like representing people.

What still motivates me after all these years is still the ability to assist people who don’t have the knowledge or the capability of maximizing what they’re entitled to receive.

We represent many people where English is not their first language, or they are certainly not educated in the ways of the world when it comes to the law.

And to be able to ease their mind, to be able to sit down with them and for them to know that they’re talking to someone who cares, who listens, and oh, by the way, will also get them the most money that they’re entitled to get, that’s incredibly rewarding to this day.
