THE CHEMISTRY OF Formula As a national boutique, Formula offers clients a commitment to excellence fueled by nimbleness, responsiveness and access to senior level counsel and service not commonly found at large firms. But there is one thing that truly sets us apart from other PR firms: Chemistry. Chemistry is the glue that keeps everything together: it's what enables our staff to work so well together, it's what allows us to develop rock-solid relationships with clients, and it's what empowers us to secure new business. Indeed, without chemistry, there is nothing.
