Abell Tax Service

Abell Tax Service has been a family owned tax preparation business since 1968 operating in the Fenton area.  We’ve specialized in individual and sole proprietor returns with the mission to provide professional, courteous, affordable tax preparation.

Abell Tax Service was established by Warren Abell Sr. at his home in the Jefferson County side of Fenton, MO in 1968.  Mr. Abell’s practice was located in his basement alongside his wonderful wife’s salon where patrons could come get their hair cut, colored, or styled while getting their tax returns prepared.  Mr. Abell grew his tax practice for 20 years until his eldest daughter, Dianna, joined the practice in 1987.  With it being in their blood, Dianna’s younger sister, Cathy, joined the practice in 1992.  Cathy’s daughter, Lara, even joined the family practice for several years as the face of the practice at the front desk.  In fact, she completed data entry for quite a few returns and has gone on to be a tax preparer in Vermont.  With all of that said, the family has successfully grown and sustained the practice for over 50 years!    

It is with great honor that we have been able to merge this practice into our family at Summit Tax and Wealth Advisory LLC.  We hope to continue their tradition of providing individual and sole proprietor returns while being professional, courteous, and affordable.  At the same time, we can expand that practice to offer corporate, partnership, and trust returns with the same level of service.


Mr. Steven C. Shorley entered the accounting profession in 1977 when he graduated from Central Missouri State University in Warrensburg, MO and going on to receive the credential of Certified Public Accountant soon after.  His career exploded in 1982 when he joined a small, local firm named St. John and Mersmann eventually working his way up to partner.  Over time, the firm expanded and evolved into St. John, Mersmann, and Co., P.C.  Under Steve’s leadership and strong work ethic the company grew to be one of the top 25 largest accounting firms in the St. Louis area.  In 1997, the company merged with a larger firm, LarsonAllen, now CliftonLarsonAllen (CLA).  One of the principal accountants of the tax division, Steve’s impact was immediate and recognized throughout the company.  Eventually he parted ways with the company to care for his family as they struggled through some medical and personal difficulties.

As quickly as he could, Steve returned to the profession and, in 2005, Steve’s son, Andy, joined him as a tax preparer at a small firm in Ballwin, MO.  Over time, Andy worked not only as a tax preparer, but helped to complete an income forecast project for a client as well as bookkeeping duties for multiple small business clients.  As the years progressed, Steve’s daughter, Michelle, and niece, Anna, would also join him in the accounting world as a bookkeeper and Enrolled Agent, respectively.

Eventually, Shorley’s Tax Accounting and Management Professionals LLC (STAMP LLC) was established by Steven C. Shorley later in his career as a way to provide a legacy that both his immediate family and extended family could carry forward.   With this same intention, we are carrying his traditions of hard work, integrity, technical superiority, and excellence into our Accounting and Management Division.
