Workers' Compensation, Federal Black Lung and Employment Law

About Daniel W. Deitrick

Daniel is the managing attorney for the Workers' Compensation Department in the firm's Pittsburgh office. He devotes his practice to the defense of workers' compensation and federal black lung matters. Daniel represents sports manufacturing companies, trucking companies, hospitals, nursing homes, school districts, vehicle manufacturers, hotels, restaurants, electronics manufacturers, construction companies, public transportation entities, grocery/retail stores and mines.

Daniel successfully defended a workers' compensation fatal claim involving a motor vehicle accident by demonstrating that the decedent claimant was not an employee of his client for the purposes of the Pennsylvania Workers' Compensation Act, while also establishing that the decedent claimant was not in the course and scope of his employment at the time of the fatal accident. Daniel also successfully defended against a claimant's allegations of entitlement to the maximum temporary total disability rate for a compensable injury by proving that the time-of-injury average weekly wage was properly calculated pursuant to Section 309 (d.1) of the Workers' Compensation Act. See Collier v. WCAB (PRS/Engles Trucking), 805 A.2d 1267 (Pa. Cmwlth. 2002).

Daniel graduated from Villanova University with a bachelor's degree in political science. He then attended Duquesne University School of Law and was awarded his juris doctor. Since beginning his practice, Daniel has focused on the litigation of insurance defense, workers' compensation and federal black lung cases.

It is solely the responsibility of lawyers and law firms to ensure that any information they provide complies with all applicable laws and rules of professional conduct.

You should be aware that the information we rely upon may not be comprehensive, or frequently updated.

Lawyers.com Client Reviews

Martindale-Hubbell® Client Review Ratings™ display reviews submitted by individuals who have either hired or consulted the lawyers or law firms.

The Client Review Rating score is determined through the aggregation of validated responses. People who submit reviews are either individuals who consulted with the lawyer/law firm or who hired the lawyer/law firm and want to share their experience of that lawyer or law firm with other potential clients. Reviewers can be anyone who consults or hires a lawyer including in-house counsel, corporate executives, small business owners, and private individuals.

Martindale-Hubbell validates that a reviewer is a person with a valid email address. As part of the review process, respondents must affirm that they have had an initial consultation, are currently a client or have been a client of the lawyer or law firm identified, although Martindale-Hubbell cannot confirm the lawyer/client relationship as it is often confidential. The content of the responses is entirely from reviewers.

Prior results do not guarantee a similar outcome and Martindale-Hubbell accepts no responsibility for the content or accuracy of any review. For more information on Martindale-Hubbell Client Review Ratings, please visit our Client Review Page

Martindale Peer Reviews

Martindale-Hubbell® Peer Review Ratings™ are the gold standard in attorney ratings, and have been for more than a century. These ratings indicate attorneys who are widely respected by their peers for their ethical standards and legal expertise in a specific area of practice.

The Martindale-Hubbell Peer Review Ratings process is the gold standard due to its objectivity and comprehensiveness. Lawyers solicited for peer reviews include both those selected by the attorney being reviewed and lawyers independently selected by Martindale-Hubbell. All reviewers are verified as attorneys through Martindale-Hubbell’s extensive attorney database. Only attorneys practicing at least three years and receiving a sufficient number of reviews from non-affiliated attorneys are eligible to receive a Rating.

What are the different Martindale-Hubbell Peer Review Ratings?*

• AV Preeminent®: The highest peer rating standard. This rating signifies that a large number of the lawyer’s peers rank him or her at the highest level of professional excellence for their legal knowledge, communication skills and ethical standards.

• Distinguished: An excellent rating for a lawyer with some experience. This rating indicates the attorney is widely respected by their peers for high professional achievement and ethical standards.

• Notable: This rating indicates that the lawyer has been recognized by a large number of their peers for strong ethical standards.

Lawyers who have received peer reviews after 2009 will display more detailed information, including practice areas, summary ratings, detailed numeric ratings and written feedback (if available). Details for individual reviews received before 2009 are not displayed.

Attorneys that receive reviews from their peers, but not a sufficient number to establish a Martindale-Hubbell Peer Review Rating, will have those reviews display on our websites.
