He received his law degree (JD) at the University of Iowa graduating with honors in 1979. He has been practicing law in Central Illinois since his graduation and admission into the Illinois Bar.

Legal ability and ethical standards ratings are published each year by the Martindale-Hubbell Law Directory. Mr. Wombacher has the highest possible rating of AV. The legal ability rating is "A" which means he is rated as very high to preeminent. The "V" rating means that he embraces faithful adherence to professional standards of conduct and ethics of the legal profession. He is also listed on the Bar Register Of Preeminent Lawyers by Martindale-Hubbell. These ratings are developed for individual attorneys by soliciting confidential opinions from attorneys who have ratings themselves and those who do not.

Mr. Wombacher practices in three (3) primary areas. First, Mr. Wombacher represents persons who are no longer able to work and are applying for disability benefits. He has represented persons before the Social Security Administration (SSA) since the early 1980's in seeking Social Security Disability benefits (SSD) and Supplemental Security Income (SSI). The disability hearing office for the Social Security Administration (ODAR) in Central Illinois is located in Peoria. These claimants have significant mental and/or physical disabilities which prevent them from working. He is a member of the National Organization of Social Security Claimants' Representatives (NOSSCR). This is an organization of attorneys and others who assist those with disabilities. He has represented persons at all levels, from initial application, reconsideration and hearing. Mr. Wombacher has one of the largest social security disability practices in Central Illinois and has appeared in hundreds of hearings before the Social Security Administration and represents clients in Federal Court. He is recognized as a Leading Lawyer in the area of Social Security Disability law. The distinction of being considered a Leading Lawyer has been earned by less than 5% of all lawyers licensed to practice in Illinois. www.leadinglawyers.com

Mr. Wombacher practices in the area of Elder law. This area of law involves Medicaid planning and asset protection advice for those individuals entering nursing homes, planning for the possibility of disability through the use of powers of attorney for the both health care and property, guardianship, estate and tax planning, probate and estate administration, preparation of wills, living trusts and special or supplemental needs trusts. Many of the special needs trusts and supplemental needs trusts are prepared for the benefit of disabled children by their parents or grandparents.  He represents clients primarily in Peoria, Tazewell and Woodford counties.  He was certified as an Elder Law Attorney (CELA) by the National Elder Law Foundation (NELF) in 2003, recertified in 2008 and 2013. He was the third attorney in Illinois certified as CELA and is the only practicing CELA in downstate Illinois. Lawyers who are certified as specialists have been recognized by independent professional certifying organizations as having an enhanced level of skill, as well as substantial involvement in established legal specialty areas. Certifying organizations require lawyers to demonstrate special training, experience and knowledge to ensure that recognition as a certified specialist is meaningful and reliable. Bill joined as a charter member of the prestigious Council of Advanced Practitioners (CAP) of the National Academy of Elder Law Attorneys (NAELA). The CAP is an invitation only Council providing specialized member benefits to NAELA's Advanced Practitioners. Membership in CAP is available to preeminent Elder Law Attorneys. Eligible Candidates must be: 1) A NAELA member for a minimum of ten years, 2) AV rated by Martindale Hubbell, and 3) be either a NAELA Fellow or a CELA (Certified Elder Law Attorney). He was selected by other attorneys in Illinois and recognized in Chicago Magazine as an Illinois Super Lawyer in the area of Elder Law. He is a member of Estate Planning Council of Central Illinois.

Mr. Wombacher also practices in the area of public transit law. He was General Counsel for the Greater Peoria Mass Transit District (CityLink) for twenty-eight years. He still represents the District on specific assignments. He is the General Counsel for the Illinois Public Transportation Association. This organization was started in the early seventies as a state organization representing public transit agencies.

He has also acted as Special Counsel to the newly formed Stateline Mass Transit District (SMTD) in northern Illinois and has done work for the Rock Island Metropolitan Mass Transit District (MetroLink). 

In addition to the defense work he has done in the public transit arena, he has done litigation defense work in the past for Home Insurance Company, Western States Insurance Company, Casualty Insurance Company, Transamerica Insurance Company, Pekin Insurance Company, Westfield Companies and Employers Mutural Insurance Company.
