What’s New at DKMO

Kerry W. Pearson Acquisition

In early January, we finalized our acquisition of the law firm of Kerry W. Pearson. Kerry is a longtime Arlington Heights resident and attorney currently transitioning into retirement.

His practice concentrated on the areas of business law, probate and real estate. Kerry will finish up ongoing matters in the coming months. In the meantime, new clients and matters will be referred to an attorney at DKMO. For more on this acquisition, see here.

Harry E. Bartosiak Joins DKMO

DKMO welcomed its 16th attorney, Harry Bartosiak, in January. Bartosiak, an Arlington Heights resident and the founding partner of Bartosiak Law Firm in Inverness, is experienced in healthcare law, corporate law, estate planning and administration and real estate. The addition of Bartosiak provides DKMO with an opportunity to expand its healthcare law practice. Two staff members from Bartosiak Law Firm also joined DKMO this month.

ABA Well-Being Pledge

DKMO is proud to be among the first law firms in the nation to sign the American Bar Association’s Well-Being Pledge. This initiative aims to improve mental health in the legal profession and increase resources for lawyers struggling with substance abuse. This month, we will meet with other members of the inaugural class to exchange ideas for creating a positive work environment.
