Of Counsel
P 512.575.6059 | F 512.840.4551


Eleanor D’Ambrosio combines her policy and regulatory experience to provide clients with proactive and responsive counsel and advocacy in utility-related regulatory and business matters, helping them provide efficient and high quality service to the public.

Eleanor brings a strong track record of public policy to her private practice, having served first in the Texas Legislature and later in state agencies. Her experience as an attorney with the Public Utility Commission of Texas, most recently as Deputy Director of the Legal Division, gives her unique perspective on the challenges in the state’s utility regulatory environment.

During her tenure at the Public Utility Commission, Eleanor was integral to several rulemakings to implement new or revise existing rules applicable to water utilities. She also represented Commission Staff in contested cases, including base rate proceedings for both electric and water utilities, wholesale water rate appeals, change in control proceedings, interim rate proceedings such as transmission cost recovery factor and generation cost recovery rider cases, certificate of convenience and necessity amendments for generation owned by vertically integrated utilities, and sale, transfer, and merger proceedings.

While in law school, Eleanor clerked in both the Administrative Law and Environmental Protection Divisions of the Texas Attorney General’s Office. Her interest in utility law was the natural outgrowth of her time spent in administrative law. Prior to law school, Eleanor served in a variety of roles for Texas state representatives, from campaign manager to legislative director to chief of staff. Her time in the political arena provides her with an understanding of how to draft and advocate for legislation that enhances and protects her clients’ interests.
