Her autobiographical cartoons focus on attitudinal barriers and stereotypes regarding disabilities, and some of the micro-aggressions that disabled people experience while living normal, un-inspirational lives. She is also a photographer of micro-scale monuments in nature and is often inspired by close-up images that people often do not notice in daily life – tree bark, dead leaves, flower anatomy, and water.

Membership Committee Head


My name is Alan Bronstein. I’m a T-3 para due to an auto accident in January, 1985. I’m married with 2 adult sons, a lawyer in NYC and a brewer in St. Croix, USVI. My wife is a still practicing accountant. After my injury I played “independent investor/trader” for a couple of years, but then decided I had to get out of the house and be around people. Long story – short: I became a chemistry teacher and drama sponsor at my old high school in Philly. Over the 25 years I taught I was honored with 2 teaching awards (picture attached of my presentation for the Freida J. Riley Award) both of which I feel very honored to have received. 

After retiring 7 years ago, I found I missed the kids. So, now I volunteer and substitute at the school. I also join some professors at Temple U. each December to perform a “demothon,” i.e. putting on a show of chemical demonstrations for middle school kids. 

Perhaps it was because I was the Drama sponsor, I began to view teaching as putting on a new show everyday for 180 days... and since I was teaching chemistry, it could be (sometimes) a magic show, as well. I tried to make it interesting for me as well as for the kids. Maybe that’s why I’ve missed it – it was fun.

Samantha Twining

Fundraising Committee Head

Samantha Twining is a full time Political Science Student, a Public Speaker, storyteller, and Disability Rights Advocate who works with individuals and organizations seeking a better understanding of accessibility, The ADA, and a disability perspective.

 At age 21, she was in a car accident that caused a Spinal Cord Injury (SCI), which left her paralyzed from the waist down. “As someone who navigates through this world in a wheelchair, It’s important for me to share this perspective so that there is a human understanding behind The ADA,” says Samantha. She has an array of platforms that she speaks on; and tailors the structure of her story in a transparent, relatable, yet powerful way aiming to amplify individual power within those who are watching.

Samantha’s professional background is in sales and sales training, but her SCI has increasingly swayed her in the direction of advocacy and policy - which inspired her to go back to school at 36 to complete her degree. Samantha is serving in her first term as a Housing Commissioner in Delaware County where she the committee chair for Accessible Initiatives. She is also an active member of the Advocacy Committee at the United Spinal national level where they work to develop policy for a more inclusive world.

During her speaking engagements, she uses her skills to captivate and engage with the crowd, leaving them with an honest interpretation of her everyday hurdles. Samantha has spoken to students of all ages, from 1st graders to medical students. “Jefferson Health has ultimately been the most fulfilling platform. Speaking with medical students as they learn their trade is important. The patient's perspective is crucial, and hearing personal stories makes them more attentive professionals.”
