Among his American clients in the years preceding World War I was Henry Clay Frick, for whom Allom furnished houses in cooperation with Sir Joseph Duveen, the eminent paintings dealer.

He purchased the house on Madison Avenue built by Carrère and Hastings in 1893 for Dr. Christian Herter[5] which the firm White, Allom & Company occupied until 1933.

Returning to London from one of his trans-Atlantic trips in 1925, Sir Charles remarked on the American work ethic and was quoted in Time magazine.

[6] In 1931, White, Allom was among the stellar cast of furnishers and decorators creating a grand but homey atmosphere for the new Waldorf-Astoria Hotel on Park Avenue.

And when the Empress of Britain was launched the same year as the "new" Waldorf-Astoria, among its modern Art Deco decors, the "Mayfair Lounge" by White, Allom was the one space in Edwardian Renaissance manner.

Charles Currick Allom worked with Sir Joseph Duveen, Horace Trumbuer, and Landscape designer extraordinare Jacque Grabier.
