Marcus Aurelius

Describe your role with the Greiner Consulting Group?

As the person accountable for operations, I wear many hats; combining the role of Controller, IT Specialist, HR Advisor, Field Operations Supervisor, Client & Vendor Relationship Manager, Social Media Strategist, and all around problem-solver. With our offices spread across the country, and our clients positioned around the world, I work behind the scenes to ensure that everything runs smoothly so that our clients receive the services they need, when they need it.

What drew you to Greiner Consulting?

After I graduated from college, Jennifer and Adele kindly offered their time to help guide me on my career search. Their guidance gave me the confidence I needed to secure a successful job and the experience to later work effectively together.

What makes you good at what you do?

I enjoy interacting with all different types of people, view problems opportunistically, and strive to be a great listener.

Where did you start your career?

I began my career in the real estate industry and was most recently working at a top 20 advertising agency in New York.

What motivates you? Inspires you?

I’m motivated by complex and challenging problems and enjoy providing advice and assistance to help others deal with complicated issues. My work at Greiner Consulting Group, coupled with my involvement in Footprints Around the World, a social impact venture that help people without limbs get access to prosthetics, have been two great sources of motivation and fulfillment. I’m also inspired by film, traveling, the energy of New York, my family, and by passionate people who make it their life’s work to be experts in their field and teach others.

Where did you spend your school days?

I grew up in Manhattan and attended the Horace Mann School. I chose Boston for college over staying in New York because it was far away enough so my parents couldn’t spy on me but close enough so they could haul all my stuff back at the end of the year. After interning with the Massachusetts state government and at RBS Citizens Financial Group, I graduated from Emerson College in Boston with a B.S. in Political Communication.

When you are not at work, what do you like to do? How do you spend some of your downtime?

Staying active is very important to me, whether its running, biking, swimming, hiking…if it gets the blood pumping, count me in. In the past few years, cooking has also become a hobby. Not long ago, I did a kitchen internship with Chef David Waltuck. I’ve found that cooking is one of the greatest ways of bringing people together and celebrating life.
