Attorney Bio

David L. Dingwell is a partner with our firm and serves as its Chief Financial Officer and General Counsel. Mr. Dingwell has been in practice since 1992. 

Mr. Dingwell’s practice is focused on estate and trust planning, probate and trust administration, and estate and trust litigation matters.  Based upon his experience in assisting clients, Probate Courts in Northeast Ohio, as well as fellow attorneys, have appointed Mr. Dingwell to assist with investigating and administering complex, high-conflict estates, trusts, and guardianships.  Plakas Mannos is able to draw upon that experience and knowledge to assist clients with understanding challenges and obstacles that often times present themselves.  Regardless of the size of a family’s estate, planning with a strategy to avoid and minimize conflict and confusion requires foresight. 

In addition to his estate planning and administration practice, Mr. Dingwell also works with attorneys, law firms, and judicial officials with legal / judicial ethics issues, risk management, advisory opinions, and expert witness services.  Having served as a Commissioner of the Ohio Board of Professional Conduct for nearly a decade, including two years as its Chairman, Mr. Dingwell has participated in dozens of legal and judicial disciplinary proceedings.  Prior to his service on the Board of Professional Conduct, he served as a member of Stark County’s Certified Grievance Committee, including two years as its Chairman.  His experience with legal ethics spans over two decades.  Based upon that expertise, Mr. Dingwell has advised law firms, attorneys, and judicial officials throughout Northeast Ohio with regard to various ethics matters.
