Nicholas Schirmer
Senior Developer

Nick never met a problem he couldn’t resolve nor missed an opportunity to learn and share something new as McG’s Senior Developer.  He also never met an Oxford comma he didn’t like. (We scrub McG content accordingly.)

Strong in back- and front-end development, Nick recently picked up using the Laravel framework and is stretching his skills in systems administration. He enjoys troubleshooting and teaching other developers. McG clients say they value Nick's focused but easy going style. 
 
He's a fervent Apple, latest-tech-gadget, and gaming enthusiast who co-created a successful Pokémon webgame. Nick enjoys a good road trip and cooking with fresh organic ingredients.

Nick hails from Pennsylvania's Lehigh Valley and San Antonio, Texas. He shares his home with his long-time girlfriend, two rescue cats and one dog, and one Leopard Gecko.  When Nick added “how to sex a Leopard Gecko” to his repertoire, “Little Dude” became “Little Miss.” 
 
Nick contributes seriously useful troubleshooting help and tech gadget news to the McG Interconnection newsletter. Catch up with him here.


Jeff Slater
Senior Developer, Lead

Jeff is all about front-end development, especially working with tools Sass and Gulp, and making sure he stays on top of new front-end dev technologies. Clients tell us -- and we agree -- Jeff is easy to work with and dependably brings creative insight and perspective to the table.

Known around McG as "Slater," he's a proud native Torontonian. Jeff supports our clients around the U.S., while holding down our Canadian office.

Jeff is an unabashed bacon fan. That said, lately he's been compensating with a commitment to healthier eating (around the bacon, we wonder?) and being physically active. Two favorite tools he's convinced will support this new regimen: a stand-up desk and the activity monitor on his Apple Watch.

Besides bacon, his not-so-guilty top pleasure is compulsively acquiring the latest Apple tech ...  no expense spared. He's an ardent fan of traveling, tech conferences, supporting the local political scene, "cats" in general, and amiibo and Nintendo. Jeff is the successful co-creator of at least one webgame we know of.


Madisyn Collier

Content & Social Media Specialist

Digital native Madisyn is versed in producing, deploying, and amplifying creative content for the web and social platforms. Simply stated, she's totally jazzed about the power of social conversation for business development. McG clients highly value Madisyn for her robust capabilities with mobile and ability to communicate brand messages for optimal audience engagement.

Madisyn is pursuing multiple degrees, in finance and in marketing and public relations. Financial Services is a key domain for McG, and Madisyn enriches what we can bring to the table for our professional services clients. 

At every opportunity, rising star Madisyn flexes her penchant for personal training, urban and product photography, adventurous travel, and using her Spanish speaking skills. Working with animals is a passion. Madisyn volunteers her time and talent training dogs for a local animal welfare organization.


Carolyn Stinson

Content & Public Relations Architect

Carolyn helps McG clients bring a voice to their brand, shape their marketing messages, and take their products or services to the right audiences.  Her credits include stints as marketing and public relations director in regional professional services firms (CPA and law) and in the legal and marketing departments of Medifast. 

A stringer for The Washington Post once told her, "You know how to frame and conceptualize stories better than just about anyone in your profession that I've ever worked with."

Carolyn has developed extensive domain experience in content marketing and PR for law, accounting, health care, financial and business advisory services, and specialty niches in the hospitality and events industry. She is the co-author of a top seller consumer health book and consults for non-fiction subject matter experts interested in writing and publishing.  

Five warmblood horses and a 200 pound Japanese mastiff "Angel" share the homestead with Carolyn and her husband.
