The Secret To Our Excellence

PARTNER:  Janet Killingsworth

“Hello, my name is Janet Killingsworth. Welcome to our website, I hope you take some time to look around at the various parts to discover why I am so proud of our firm. I have been practicing as a CPA in Metro-Atlanta since 1985. We are a CPA firm that offers personalized accounting and tax services to small businesses and individuals. We are also your neighbors in Roswell and we care about the community as much as you do. I founded Killingsworth CPA, P.C. in 2001 to serve our clients with a high level of service to business owners and those individual taxpayers who seek the level of trust and confidence from a team of senior-level CPAs and other professionals. I wanted from the beginning to be able to make certain that our clients have at least a senior level CPA looking after their account so that they have the confidence in knowing they are well cared for. In 2017, I asked Lynn Spencer to become an equity partner as our business began to grow rapidly over the past couple of years. We formed Killingsworth Spencer, LLC to become the marketing arm of the practice. We will continue to roll out additional services that our clients are asking us to deliver on their behalf.

PARTNER: Lynn Spencer

All clients have challenges that are unique to their individual situations. I am passionate about our firm serving these essentials and providing clarity and confidence to each. My goal is to make sure that all our clients know we are partners dedicated to their success, and that all feel well served by Killingsworth Spencer.

My background begins with a B.S. degree in Accounting from Wayne State University in Detroit, MI. While in college, I was an Administrative Assistant for an international benefits and consulting firm and stayed on as a Retirement Benefits Specialist after graduation. Upon marrying a U.S. Navy sailor, I got
the value of experience in different fields as we moved to new duty stations. I worked for regional bank in Human Resources in Connecticut, co-managed a Temp Agency in New York, and managed a large Marina in Washington State, all before having children and then choosing to Home School them, leading
to many volunteer opportunities in my community through those years.

Homeschooling, community involvement, and the different work experiences made a natural path to Partnership as CFOO with Janet Killingsworth soon after joining her firm as an admin in 2015. I encourage all to live each moment to the fullest; one seldom knows what opportunities lie in our

I have been involved in the accounting and bookkeeping profession for over 25 years and I love working with numbers. I especially like to help our clients be able to make better financial decisions when they have up-to-date books and records. I grew up in Cape Cod, MA, and I love the Ocean. Yes, the water is always cold, and I am a Patriot’s fan. I must admit that I prefer the warmer waters of the Gulf of Mexico. I love music (especially Fleetwood Mac and I have seen them live at least ten times), travel, movies, reading, and a good steak. I have a 26-year-old daughter and we still enjoy spending time together when we can.

I am an Office Administrator here at Killingsworth Spencer since 2017. Working here, my knowledge and interest in the tax field has grown.

I was born in Detroit, Michigan. I grew up competing in gymnastics from an early age and believe that experience helps me in my day-to-day duties here at Killingsworth Spencer. In 2012, my family and I relocated to Milton, Georgia.
