GROW Careers

The GROW Careers Program has paired over two dozen interns with mission-driven organizations since its inception in 2019. Trellis matches young people aged 18*-26 with regional nonprofits and social impact businesses to provide meaningful, paid work experiences. These experiences range from 60 to 160 working hours and include one on one and group mentoring and professional development. Placements are primarily in Montgomery and Chester Counties, Pennsylvania (Lenapehoking), with limited hybrid-remote options.

Program Details

Aged 18*-26
*Prior Trellis program participants under 18 may qualify

60 – 160 hours

Applications open for Summer placements: February 2024
Applications for Fall placements due by July 1, 2024

If offered a position, the intern has the final decision on their placement. Start and end dates are determined based on the needs and availability of both the intern and the host.

NOTE: Applying does not guarantee placement for hosts or interns.

Matching Young Talent to Local Needs

The matching process is designed to determine if both the intern and the host will be a good fit with the other.
Both young applicants and potential host organizations fill out an application and undergo an interview process with Trellis staff.

The intern applicant will interview with between 2-3 potential host organizations, which can range from phone/Zoom interviews to a brief day of shadowing or volunteering for both parties to get to know the other.
Ultimately, the youth applicant chooses their final placement.

Ongoing Mentorship and Support
The professional development workshop series is comprised of two tracks:

  1. Those who are looking to lay their career foundation
  2. Those who want to build the next step on their career ladder

From creating a LinkedIn profile to building a portfolio, we meet interns where they are in their career journey. Staff meet regularly with both the intern and host to ensure smooth and mutually beneficial experiences.

After the intern successfully completes the GROW Careers Program, they are invited to celebrate at the annual Networking Mixer and are invited to the Trellis for Tomorrow alumni group, a space where we continue to share resources and opportunities.

Where the Placements Happen

Since the inception of this program in 2020, we have connected GROW interns with the following organizations:

Check out what our participants and hosts
have to say about their experiences!

“I definitely feel more confident going to college and knowing I’ll be able to use what I learned in the future for networking and internships & jobs. Additionally, I felt supported and comfortable throughout the entire internship process from the very start – even before being matched”


Intern Innovation Training & Consulting

“I appreciated having a resource that helped me better myself in the professional sense, with advice and mentors I can turn to with questions… I enjoyed getting to meet other individuals around my age and in similar situations to me. It made me feel less anxious about my future. I think most of the benefit I received from the program that I received is general advice about how to conduct myself in the professional setting.”


Intern Trellis for Tomorrow
“[She] was one of the best interns I’ve had. She understood the tasks I needed her to do, worked extremely hard, and after the first couple of days, knew what to do and did it without having to be asked.”

Elizabeth G.

Executive Director Crescendo

“Outstanding experience with Trellis. Bob was a great partner…Loved and appreciated this opportunity, and I look forward to a shared, cooperative future!”

Sean H.

Executive Director Barnstone Art for Kids

“Abbey fit right in and now is a member of this year’s student leadership team, working with 16 other high school students from 4 schools. The placement was perfect! Thank you.”

Ken H.

Green Allies
“I really liked the individual check ins because they reminded me of my goals and helped me reflect on my internship. The value of the internship comes from the reflections so they are extremely important.”

Matthew F.

Intern Orion Communities
“Working with other interns on different steps of their career paths was very cool, I felt I was able to mentor some younger interns which was a very cool experience as it made me happy to help someone else. At the same time I was helped by other interns further along in their career paths.”

Kiera C.

Intern Barnstone Art for Kids
“I think it’s a really great resource for people who aren’t in college, or don’t plan on it, or just have no clue what to do next once they’re out of school. I love that it’s a free program run by great people. I do think it has and will help me moving forward”
