Calcium: The Growth Element

In today's complex healthcare marketplace, brands continue to be a potent force. Brands, among other things, are vehicles for engagement, creating strong connections between businesses and the people they serve. When brands are vibrant and alive, businesses flourish. By maximizing brand health, Calcium is able to deliver the kind of powerful business impact clients are seeking.

Given the significant challenges being faced by today's life sciences companies, brand nourishment requires strategic thinking of the highest order. At Calcium, our strategic acumen has been honed over many years of accumulated real–world experience; across a wide span of client engagements; and in a diverse range of categories. Through our industry networks, we're able to track and identify the healthcare landscape changes that affect strategy–enabling Calcium to deliver more effective solutions. The strong strategic foundation we build–and share with clients–supports all of the critical work we do at Calcium.

Our unique form of brand nourishment consists of a steady stream of powerful, engagement–building ideas–strategic, scientific, creative, and technical ideas. The Calcium culture emphasizes the constant genesis of new ideas to drive brand and client growth. In our view, ideating freely and vigorously on behalf of clients–and constantly asking "what if?"–is the lifeblood of what we do.

Isn't it time to experience a more nourishing agency relationship? We’re Calcium–let's build something strong together.

What we do
delivering balanced brand nutrition through
The Growth Process

market analysis


Developing a deep and comprehensive understanding of the product, category, and all stakeholders. Includes a rigorous competitive assessment. Reveals critical unmet needs and market opportunities.



Formulating deep market and customer insights into powerful plans of attack. Establishing the strategic framework–in a clear and systematic way–for all downstream marketing initiatives.



How to situate your brand in the minds of (potential) customers. Precisely defining the right strategic messaging that will most powerfully resonate with–and activate–specific customer segments.



Skillfully combining verbal and visual elements into brand expressions that deliver maximum impact and engagement. Invoking both the heart and mind to create executional magic that captivates your audiences and, thereby, moves the needle.



The art–and science–of effective message delivery. Creating the most innovative and compelling programs and initiatives–all strategically aligned. And utilizing the most validated online and offline channels to get your message heard.

At Calcium, we utilize a proprietary system called 'The Growth Process™' to strategically guide and unify our various work streams. When all strategic, creative, and tactical solutions share the same underlying brand DNA, brand impact is magnified–and customer activation is intensified.

We’re on the forefront of technology in this rapidly changing digital world. We know where patients live (in the online sense), what they're looking for, and how to find them. Our customized and measurable initiatives break industry benchmarks. Our deep digital knowledge and skill set empowers clients by providing well-defined user experiences, platform agnostic design, content strategy, complete in-house programming, and measurement. At Calcium, digital is not a silo–it’s a vital part of the integrated marketing solutions we offer to clients.

Our services are further enhanced by synergistic strategic partnerships. Our work with Boston Healthcare enables our clients to gain a better understanding of market access, payer communications, and reimbursement issues; it also gives them the ability to receive critical health economics and outcomes research. Plus, our strong partnerships both with Google and comScore provide clients with unique, measurable opportunities to drive brand and business growth.

The Approach
The Approach
creativity is in our bones

Creativity is the force that propels content into the hearts and minds of audiences. Without imagination and creativity, messages will disappear into the vast ocean of content that customers face every day.

Whatever the medium (online or offline), our creative work at Calcium emphasizes freshness, impact, and memorability–but also strategic alignment. In our view, the very best creative displays verbal, visual, and conceptual firepower while also staying true to the brand’s well-defined strategic imperatives. For us at Calcium, it’s not creative unless it moves someone . . . and moves the needle.

The Recognition

Rewards of awards

We work for our clients and their brands–not for awards. Still, it’s gratifying when our client work–and even our entire agency–is recognized by our industry peers for quality, uniqueness, and effectiveness. Our ultimate success metric is moving the needle for the clients we serve. But winning as many industry awards as we have also provides welcome validation for our hard work and high standards. In our world, winning work tends to be powerful and effective work–so we are absolutely committed to continuing our winning ways.

Among the recent awards we've won:

  • Over 58 awards from major shows
