About Marc

Full Bio

What do you like most about being part of O'Brien?

I love interacting with the clients and the team. We are honored that our clients share their life goals and their journeys with us. I’m proud that we deliver best-in-class financial thinking and concrete results.

Can you share one secret to success that has been helpful to you in career?

Know yourself, put your heart first and pursue what smites you with passion! Next take some time, think about the options and seek perspective from others that you respect.

If wealth management were an ocean, what kind of creature would you be?

Sea Lion. The most recent Sea Lion I recall was having a grand time in the sun basking on ocean rocks. They are known to be intelligent, especially protective of others and long of memory. Not a bad resume!

What would your co-workers say is your superpower?

Being myself and making the complex straight forward in an industry that can be laden with jargon.

You're a new addition to the crayon box, what color would you be?

Look-on-the-Bright-Side-Yellow. Yellow is often associated with energy, clarity, honor and joy. As an optimist at heart I usually focus on the positive.
