Colleen HR Recruiting Specialist


Founder, SPHR 

Colleen Drennen Pfaller knew that she wanted to be in HR since she was a senior in high school. Legend has it, she told her roommate in college that she was going to launch her own firm one day. So all of this—it’s her dream come true! 

She earned her BA & MS In Human Resources Management from Xavier University and has achieved her Senior Human Resources Management Certification (SPHR) and Society of Human Resources Management Senior Certification (SHRM - SCP), which are the highest distinctions in her field. Her background includes 15 years of experience in the field, including companies like Samuel Adams Brewery, Comair, and Jim Beam. 
She launched A Slice of HR in 2017 after learning that there is a demand in the market for fractional HR and recruiting, which all paired nicely with a flexible schedule for a growing family and a passion for building dynamic teams. 

That’s when she found her life’s work: helping mid-sized companies leverage employee enthusiasm to build their brands. 

Outside of work, she enjoys Avenger movie nights, Xavier basketball, Sycamore Youth Sports, long drives across the U.S. (especially when there are lots of stops at weird tourist traps), and everything else that comes with hanging out with her husband, Keith, and their three incredible boys. 

She is also a reader, writer and (reluctant) speaker. Her HR expertise has been featured in Money Magazine, NPR’s Marketplace, Thrive Global, CareerBuilder, Spark Hire, National SHRM, Disrupt HR, and she writes a column for HR Today.

Meagan HR Consultant


HR Consultant
Virtual/Cincinnati Focus

Meagan tried not to follow in the footsteps of her father, who was the Director of Organizational Development at Coors Brewing for more than 20 years. But after earning a degree in Agricultural Business from Colorado State University and a short stint as a Lab Tech, Meagan found her passion in HR! 

Meagan was an HR Manager in the medical field at ResCare for more than 10 years and then spent another 3-plus years at an environmental company before joining A Slice of HR in 2019. Her clients adore her, and she has implemented countless strategic HR initiatives, onboarded and greeted hundreds of new employees, and is the “cleaner-upper” of any communication issue.

Meagan enjoys working in HR because we have the ability to help people be successful and happy at work. 

She is “mom” to a sporty 8-year-old and twin 3-year-olds. She enjoys cheering on the Broncos, Reeses Cups, and listening to “Oldies” music.

Katie HR Consultant


HR Consultant, PHR
Cincinnati Focus 

Katie is full of energy, always smiling, and on the ball when it comes to moving forward and getting things done.

Katie has a Bachelor's in Personnel Management from the University of Cincinnati and a Masters of Human Resources Development from Xavier University. She currently holds her Professional Human Resources Certification (PHR) and has more than five years of experience in HR Management & Recruiting in the Marketing & Advertising and Banking industries before joining Slice in 2020. 

When the Slice team interviewed Katie, she was working as a server in a German restaurant in West Cincinnati while raising six kids. We figured if she could do that, she could do anything! We are so lucky that Katie chose A Slice of HR to make her re-entry into the world of HR. 

Katie likes HR for the versatility. You never work on the exact same thing twice! 

When Katie isn’t doing HR, she’s spending time with her family and being super enthusiastic about them and their activities. And during her down-time, you might find her unwinding with some wine and Keno at a local west-side establishment.

Audrey HR Recruiting Consultant


HR & Recruiting Coordinator

Audrey is our jack of all trades and secret weapon at the firm. She has a degree in Interior Design which means she likes to approach every problem creatively. You can always count on her to ideate new solutions that benefit the team (and are graphically pleasing, of course). Collaboration is also her thing, so you can always expect to be well-heard when you work with her.


When Audrey left the Interior Design world for an office job at a Benefits Brokerage, you may have thought it wouldn’t be the right fit. Audrey will argue to this day though that office jobs are way cooler than people give them credit for. She there gained a strong foundation in Employee Benefits while also getting her foot in the door in the HR Department when she took an administrative role. It was then she learned that Human Resources is her true calling!


Audrey’s yellow brick has now led her to A Slice of HR where she assists in recruiting projects along with managing our social media accounts. She is currently working on becoming SHRM certified and is looking forward to building her career in HR with us.


When she isn’t working, you can find her at home (probably watching Gilmore Girls) with her husband, a 7-month-old puppy, a 5-month-old kitten, and the senior cat who runs the place.  She enjoys reading long books and being outside. And don’t get us started about her love for pancakes!
