About Mr. David B. Fischer, M.P.H.

David Fischer counsels clients on environmental, policy, and health and safety matters, with a concentration on the Toxic Substances Control Act (TSCA) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). He is a registered lobbyist and advocates for clients before the U.S. Environmental Protection Agency (EPA) and Congress. Prior to joining Keller and Heckman, David served as the Deputy Assistant Administrator for the EPA’s Office of Chemical Safety and Pollution Prevention and held senior-level positions at the American Chemistry Council (ACC).

David’s extensive experience at the EPA has enabled him to build strong, longstanding relationships that support clients in navigating the Agency’s regulatory landscape. He also has significant relationships with other federal agencies. Leveraging these relationships, David efficiently facilitates communication between clients and the appropriate federal authorities, helping to streamline interactions and expedite the resolution of complex legal and regulatory matters.

In addition to TSCA and FIFRA, he has experience with numerous other statutes, including the Safe Drinking Water Act (SDWA), Emergency Planning and Community Right-to-Know Act (EPCRA), and the Food Quality Protection Act (FQPA).

David’s clients include domestic and international industrial and specialty chemical manufacturers and the trade associations which represent them. Clients seek his assistance on new chemical approvals, chemical and pesticide risk evaluations, and risk management rulemakings because of his deep understanding of EPA, its internal science policy apparatus, and its many organizational pieces that are collectively responsible for all aspects of TSCA and FIFRA.

As Deputy Assistant Administrator (DAA) for the Office of Chemical Safety and Pollution Prevention (OCSPP) at EPA, David was deeply involved in TSCA implementation, with a particular focus on risk evaluation of existing chemicals, and all aspects of FIFRA implementation. In addition, he worked with the Assistant Administrator on the technical and administrative aspects of OCSPP, an office with over 1,000 staff. He also assisted in matters pertaining to the Agency’s programs under multiple federal statutes including TSCA, FIFRA, the Federal Food, Drug, and Cosmetic Act (FFDCA), and the FQPA, and provided policy advice and recommendations to the EPA Administrator.

During his tenure at the ACC, David co-managed the Chemical Products and Technology Division (CPTD), where he led the implementation of the 2016 amendments to TSCA.

David is frequently invited to speak at conferences and has authored numerous papers on environmental matters.

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.
