What’s In A Name?

iOS Is Our Name. Literally.

Originally conceived and created as Big Ben Parliament Creations by husband and wife team Nick Reviglio and Holly Hartzell-Reviglio, it didn’t take long for them – for US – to see “the forest through the trees” in our own name.

By adding an “S” to our name, we plainly reflect our desire to develop applications that clearly demonstrate our successful, long-term partnership with Apple-based solutions.

iOS is where we live, natively speaking. RevigliOS.


Meet Nick & Holly.

Programmers and developers since 1998, Nick Reviglio and Holly Hartzell-Reviglio are native mobile application developers who evolved in lockstep with the explosion of mobile app demand ushered in by the smartphone revolution.

Based in Reno, Nevada, the Reviglios (Nick and Holly) met after Holly had moved to Las Vegas from Pittsburgh to become an elementary school teacher. Nick worked first as an estimator for Western Nevada Supply before opening his own graphic design company. 

Las Vegas would eventually be where they cut their teeth as designers, programmers and eventually, application developers — spending many intensive and fruitful years on the design, programming and application side of the gaming industry for globally recognized gaming concerns.

For almost two decades, Nick and Holly have brought a programmer’s practicality and solution-driven workflow to application development for business and industry, creating public and private apps that range from an interactive children’s app that joyfully connects kids with Santa Claus, to an unforgettable app excursion into the World of Froud co-created by Brian and Wendy Froud.

Nick and Holly have also created a detailed 7-book library of interactive “how to” iBook applications used by the water and sewage industry, to large-scale business apps that provide unparalleled connectivity, access and control for sales and marketing within the gaming industry.

The Reviglios have witnessed first-hand the power of positive application development, and welcome the opportunity to do so for your business as well.
