Diane E. Feuerherd

"Common sense, with thorough preparation, is what sets us apart. We take great pride in serving our clients and their families, often for generations."



Diane Feuerherd chairs the litigation practice at Miller, Miller & Canby. She is an appellate and trial attorney, focusing on business, estate, real estate and eminent domain litigation in the Maryland state and federal courts. Her clients, which include families, small businesses, and large corporations, trust and credit her thorough preparation, advocacy and candor, in taking a case from the initial meeting through trial, any appeal, and successful resolution.

Annually awarded the Super Lawyers Rising Star accolade, Diane reached the rare benchmark of successfully advocating cases, including jury and bench trials, at each level of the Maryland State Courts (District Court, Circuit Court, Court of Special Appeals and Maryland’s highest court, the Court of Appeals), in just her first two years of practice.

Known in Maryland for her appellate work, Diane completed a two-term appellate clerkship with the Honorable Lynne A. Battaglia of the Court of Appeals before joining the firm in the fall of 2013. Her work includes referrals from other attorneys as well as amicus curiae (“friend of the court”) organizations, before the state and federal appellate courts.   She serves as a contributing editor for the Maryland State Bar Association’s (MSBA’s) Maryland Appellate Blog and is a contributing author to the treatise Appellate Practice for the Maryland Lawyer: State and Federal.

Outside of the courtroom, Diane has remained dedicated to serving and improving the legal profession, at the local, state and national level, for the benefit of attorneys and the community at large. She serves on the MSBA’s Judicial Appointments Committee, Secretary and Board Member to the Maryland Bar Foundation, Barrister of the Montgomery County Inns of Court, and Member of the Peer Review Committee. In 2023, she was appointed by Governor Wes Moore to the Appellate Judicial Nominating Commission for the state of Maryland. In addition, she is an Associate Member of the Owners’ Counsel of America, a national network of experienced eminent domain attorneys who represent property owners.

A native of Montgomery County, she obtained her undergraduate degree from the University of Maryland’s Robert H. Smith School of Business and then graduated summa cum laude from the University of Baltimore School of Law. She lives in Rockville with her husband and two children.


Diane's abilities in the courtroom were unbelievable. Her attention to every detail was well thought out and remarkable. We are extremely happy with the outcome.

Donna and Diane defended Catalina Pool Builders in a construction arbitration. In the face of a large damages claim, they succinctly and thoughtfully made legal arguments and cross-examined the claimants’ witnesses. As a result of their work, the arbitrator denied the claimant any award. Needless to say, we are very happy with their work and the results achieved.

Diane was tremendous in her preparation for trial, approach to my case, and ability to adjust and persuade. I put my complete trust in her and was blown away. I'm grateful that she fought for me and prevailed against what I thought was an injustice.

Brian Reap, Business Owner

Diane Feuerherd and Donna McBride of the esteemed law firm of Miller, Miller & Canby represented me in a contentious, protracted civil litigation over a challenge to my mother’s estate planning and decisions. My respect and gratitude grew as they navigated the complexities of an estate challenge. From the beginning they strategically anticipated and acted to facilitate the final decision in my favor. Diane and Donna are individually accomplished with extensive knowledge about the intricacies of estate litigation. Their individual strengths complement each other as they become a formidable team; they are gracious, direct, and purposeful in all interactions. Diane took the lead at a four-day trial masterfully setting the stage in her opening, providing key evidence and testimony during the trial, and culminating in a brilliant closing to expose the subterfuge attempted to discredit me and my actions. Donna partnered with Diane throughout with her extensive expertise and knowledge. Diane and Donna are supported by staff members who provided assistance to me whenever needed; Catherine Schombert, Kate Martino, and TaNika Newman went above and beyond with kindness and exemplary service. They each ensured my needs were accommodated while navigating these proceedings. Miller, Miller & Canby, Diane Feuerherd, and Donna McBride are recognized nationally and locally. I will be eternally grateful for their counsel on my behalf.

Representative Cases

Baltimore City v. Kevin Davenport

Baltimore City v. Kevin Davenport

Circuit Court for Baltimore City, Case No. 24C18005103: Ms. Feuerherd represented a couple who had owned and operated and/or leased a corner grocery store for more than 25 years, before Baltimore City targeted the property for condemnation. Prior to the jury trial, the City’s offer to purchase the property was just $36,000. But the grocery store was income-producing rental property, with a second floor having potential for residential apartments; capitalizing on this value, Ms. Feuerherd successfully persuaded the jury to return a verdict of $196,250.

Chod v. Montgomery County Board of Appeals

Chod v. Montgomery County Board of Appeals

Circuit Court for Montgomery County, Case No. 398704-V: On behalf of a local commercial property owner, Ms. Feuerherd challenged the Water Quality Protection Charge (also known as a “rain tax”), through the administrative appeals process to a successful appeal in the Circuit Court for Montgomery County.

Montgomery County v. Phillips

Montgomery County v. Phillips

445 Md. 55 (2015): Before the Court of Appeals of Maryland, Ms. Feuerherd briefed and argued on behalf of owners of a family farm, and persuaded a majority of the Court that Montgomery County overcharged its farmland transfer tax in violation of the state tax cap.

Tomares, et ux. v. Poss, et al.

Tomares, et ux. v. Poss, et al.

Circuit Court for Montgomery County, Case No. 418365V: A family retained Ms. Feuerherd and Miller, Miller & Canby after an old gravel road, which provided the sole access to their property, was cut off by a neighbor who challenged that the road was a private driveway. Navigating through 230 years of state, county and railroad records and title history, together with a myriad of expert and lay witness testimony and complex legal issues, Ms. Feuerherd successfully proved that the gravel road was indeed a public road dating back to 1793.
