Besides providing voices for numerous incidental characters in series such as Jeannie, Alberoni is best known as the voice of nasty rich-girl Alexandra Cabot from Josie and the Pussycats;[1]: 545  "superhero-in-training" Wendy from the first season of Super Friends; the heroic robot Bo in Mighty Orbots;[1]: 689  and Glumdalclitch in The Three Worlds of Gulliver.

After her family moved to California, Alberoni started modeling at age two, and shortly after, took up dancing lessons, joining her older brother Roy.

She used the stage name Sherry Allen[2] upon the advice of her first agent, who thought some casting directors might not hire an ethnic talent.

Episodes from the second season are unavailable for viewing today, as the studio hasn't released production numbers from that year on video or DVD.

She recalled in later years that director Sidney Miller would often change her lines to include many sibilants, so fond was he of hearing her lisp.

Throughout the 1960s Sherry Alberoni appeared on episodes of many television series, such as The Donna Reed Show, The Farmer's Daughter, Ripcord, My Three Sons,[2] The Man from UNCLE,[2] and The Monkees,[2] while also doing bit parts in minor films.

[1]: 324  Alberoni also took a regular part in entertaining Marines at Camp Pendleton during these same years for a monthly production called "The Julie London Show".

It was also in the late sixties that she began doing voice work for animated series, like Josie and the Pussycats, Super Friends, and in 1984, Mighty Orbots.
