About Us


Sara Slabinski - Owner/Accountant/Bookkeeper

Prior to SJS Accounting LLC, I worked for a financial institution for 8 years. This is where I found my passion for helping and working with small businesses. While working for the financial institution, I receive my Degree in Business with an emphasis in Management. Shortly after receiving my degree, I found a job with a small cell phone tower company as their staff accountant.

SJS Accounting started because of a business owner who saw my passion for small businesses. This encouragement allowed me to establish the company in 2017 and receive my first client shortly after. Bookkeeping allows me to help small businesses with their financial needs. Combining my banking experience with my bookkeeping experience gives me an advantage to helping small businesses with financial planning, business budgeting, and projections. 

My husband and I have 2 wonderful boys. Sports and outdoor activities are our favorite activities. We are a family oriented small business.

Our Team


Alyssa Hartman - Partner/Payroll Expert

Hello! I have 12+ years experience in Small Business General Management.  I worked my way into Management the old fashioned way - from entry level all the way up to the top.  I've always craved obtaining new skills I have worn many hats during my career in business management, but I most thoroughly enjoy specializing in Payroll and Human Resource services. 

I was born in Minnesota on a hobby farm, and have participated in many horse shows and rodeos throughout my life. My husband I along with our two wonderful children live in the Queen Creek area on a growing mini-ranch.  We enjoy everything outdoors from camping and fishing, to hiking and horseback riding. 

Now that I have joined the SJS family, I am so thrilled to be able to focus on what I enjoy the most: Close knit business relationships with my clients, providing an intimate one-on-one atmosphere with the ease of our one-stop-shop values. Currently, I am providing Payroll processing services, as well as employee Hours tracking and Paid Time Off tracking.  I look forward to broadening my services offered, based on client needs that come up in the future.
