Meet Tina Mullin, Roundtrip’s Chief Financial Officer


Headshot of Tina Mullin

Tina Mullin is the Chief Financial Officer at Roundtrip. Tina began her career as an auditor with KPMG and since leaving has held progressive financial roles in small-start up organizations across multiple industries, including pharmaceutical research, staffing and healthcare.  Throughout her career she has participated in multiple transactions on both the buy and sell side.  Tina is passionate about helping smaller organizations grow and mature their financial reporting to ultimately be a resource center for the organization.  Tina graduated with a bachelor’s of science in Accounting from Rutgers, The State University of New Jersey.

Tina, what project at Roundtrip have you worked on that you are most proud of? 

The work I am most proud of during my time at Roundtrip has revolved around bringing clarity of financial information to users both internal and external to our organization.  One specific highlight is the full revamp of our invoicing process, including the establishment of an easily accessible, secure method for delivering invoice details to our customers.  Combined with relationship building, this has allowed for a better understanding of invoices and has significantly accelerated customer payments. 

What mentor or prominent figure has influenced you in your career and why? You can share more than one. 

After spending my early career in public accounting, I then had a controller who gave me my first opportunity in an early-stage organization.  It was there that I found my passion for small start-ups.  Together, we were able to establish the finance department as a resource to the organization, and educate those not in the department on the financial operations of the business.  That service mentality has stuck with me throughout my career.

Can you share some of your favorite books? 

I have two favorites.  The first was a recent read lent to me by a member of my book club, “Mad Honey” by Jennifer Finney Boylan and Jodi Picoult.  I truly couldn’t put it down.  The second book is one I go back to often, “Grace Not Perfection” by Emily Ley.  I found this book as I started navigating life as a working mom after having my first daughter and trying to do it all.  It has definitely helped to shift my perspective. 

What future do you envision for your team at Roundtrip in the next two years? 

I have two big goals for my team.  The first is to continue automating our processes to allow us to scale with the organization without the need to add additional resources to support an increased volume in transactions.  The second goal is one that I have had in each role I have held: to truly shape the department to be an accessible resource center for the organization. 

Tell me about your hobbies and things you enjoy doing in your free time.

In this phase of life, much of my free time is spent with my husband focusing on the hobbies of our kids.  I have two daughters, currently 10 and 8, who are involved in multiple activities.  I love getting to watch them do what they love.  I also am, and have been for a few years now, an aspiring runner.  I have participated in multiple Run Disney events over the past few years, which allows me to get away for a weekend or two a year to focus on this hobby. 

If you could donate $1million to any organization, what organization would it be?

Supporting the American Cancer Society will always be near and dear to my heart.  When I was in high school, both of my parents were diagnosed with cancer within the same year.  My mom is a 30 year breast cancer survivor, but we unfortunately lost my dad to non-hodgkins lymphoma when I was a freshman in college.  I can only hope that the research moves quickly enough that my girls won’t have that same worry as they get older.
