Our Team

Dwight Langhum, president and CEO


In his current position as a communications counselor, Dwight Langhum b​rings clients nearly 30 years of communication​s experience, honed in both the public and private sectors. A professional communicator who sharpened his public relations skills in the intense cauldron of New York City politics, Langhum left a senior vice president position with Fenton Communications (a pioneering, cause-related marketing firm) to launch Langhum Mitchell Communications (LMC) in 1998. Since then, he has provided advice to the principals and senior staff of more than 200 clients.

As LMC president, Dwight consults with a diverse clientele on matters of communications, public affairs, social marketing, politics, and relationship building. His clients have included: major foundations, universities, and cutting-edge organizations. His expertise in strategic communications planning and counseling is, perhaps, his most valued asset. He and his firm have worked primarily with nonprofits, helping them tell their stories more effectively to achieve their stated goals. This work is often of the David vs. Goliath type and LMC  delivers significant results that help clients garner more resources and/or greater impact. 

LMC's international work includes helping to brand the Goldman Prize as the "Nobel Prize" of the grassroots environmental field; furthering the protection of cultural products in Jamaica; and developing and promoting cultural heritage tourism for South Africa. ​

Before striking out on his own, Langhum served as assistant press secretary to NYC Mayor David N. Dinkins. He also ran the public affairs offices of two of NYC's largest agencies—the Housing Authority and the Department of Transportation. Langhum has served in two different publishing capacities, first in Harcourt Brace Jovanovich's editorial department and later as vice president of communications/marketing for Castle Connolly Medical, a leading consumer healthcare publishing concern.

Dwight maintains an extensive network of elected/appointed officials, prominent business people, journalists, educators, nonprofit leaders, marketing, and public affairs professionals. When needed, he and his firm form strategic partnerships to ensure quality service.

Dwi​ght is a graduate of Pomona College and attended University of California Hastings Law School. He is married to Cheryl D. Fields and lives in Northern Virginia with their two school-aged children: Mandela and Indira.

Langhum Mitchell Mourns Death of Co-Founder, Niki Mitchell

​​It is with heavy hearts that we announce the untimely death of our dear friend and co-founder, Nikita “Niki” J. Mitchell.

Niki was smart, passionate and deeply committed to the issues our firm believes in and the people for whom we fight.  We could always count on her keen political insight and tireless sense of humor to carry us through the ups and downs, curveballs, and mean-spiritedness that often accompany fighting "the good fight.” We will sorely miss her happy warrior attitude.


Our heartfelt condolences go out to her family and her extensive network of friends across the globe.
