Mike Patterson, Developer


Mike is a Chicagoan, born and raised. After finishing his bachelor’s degree in Computer Engineering, he moved to the Windy City full-time to work as an advanced software engineer for an eDiscovery software company. He’s led some major projects and also supports summer interns as an intern mentor. Mike’s passion for software development plays a huge role in his non-work life, and he’s using his passion toward web application development for Girls With Guts. Although he doesn’t have IBD, Mike is a proclaimed IBD advocate and caregiver, by sharing in the IBD world with his girlfriend, Mandy. When Mike isn’t furiously coding into the night, you can catch him at nearly any Chicago sporting event - well, maybe only the Cubs and Blackhawks.


SAMII, volunteer


Samii was diagnosed with Crohn's disease in 2006 at the age of 20. She has been on nearly every medication and also has several other autoimmune diseases such as RA, Sjorgrens, Lupus and epilepsy.

Despite her diagnosis, she works as a pediatric oncology nurse, fosters children and runs summer camps for kids with medical/social needs.

She has been a part of Girls With Guts since late 2012 and is passionate about advocating and educating the community about IBD. 

When Samii is not working tirelessly as a humanitarian you may catch her at the dog park with her pup, Utley.

Angela cohen, twitter manager


Angela was diagnosed with Crohn’s disease in June 2010 after an emergent bowel resection with abscess. Along with Crohn’s, some of her diagnoses include psoriasis, Arthritis, PTSD, PCOS, EDS, Fibromyalgia, Asthma, Migraines (abdominal and head) and multiple forms of Dysautonomia including POTS.

She enjoys long walks to the fridge and sarcasm. However, her greatest pleasure comes from spending time with her family, education events about pretty much anything science related (especially IBD), Twitter Chats, doing what she can to help spread awareness, and spending time with her three rescue cats. 





A Michigander by way of the East Coast, Meghan has a passion for helping others. She holds a B.A. in communication from Western Michigan University and a M.A. in communication from Oakland University. She has been helping students and parents navigate the college-going process for over a decade.

Although she does not have IBD, she has witnessed the devastating effects of the disease on close friends and family. She has seen the positive impact Girls With Guts has made in the lives of women with IBD, and when offered an opportunity to serve on the Board of Directors, she jumped at the chance to be a part of an amazing community.  

When she’s not working or advocating for IBD, you can find her obsessing over otters, her dog, Dot, and her newborn son, Michael.
