How To Build Long-Lasting Relationships At Your Summer Internship

This is a sponsored feature. All opinions are 100% from Her Campus.

Participating in a summer internship can be one of the most rewarding opportunities of your career. You can gain valuable experience, cultivate new skills, find mentors, and build meaningful professional relationships. Sending a card can be a thoughtful way to stand out during the interview process, make a lasting impression throughout the summer, and express gratitude to your supervisors and mentors. It’s also a great way to ensure that your relationships stay strong, long after your internship term has ended.

Whether you want to thank your boss for being a great leader or share your appreciation for a coworker, these six cards from Hallmark can help you leave a lasting impression and continue growing your relationships during your summer internship and beyond. 

For your internship supervisor

If you want to build long-lasting professional relationships, be sure to always thank your boss! Trust me, sending a handwritten card can go a long way — plus, it’s a thoughtful, intentional way of demonstrating your appreciation for your internship opportunity. This sophisticated gold and white card is the perfect way to say “thank you” to your internship coordinator, supervisor, manager, or any leader you’ve worked with. The acrylic calligraphy design is beautiful and will be sure to help you leave a lasting impression.

Writing inspiration: “Thank you for your invaluable mentorship over the past few months. I have learned so much under your guidance, and feel grateful to have had the opportunity to work with you so closely.”

For the coworker who brightens your day

Summer internships can be super busy, with lots of tasks and projects to get done in just a few months. Being flexible, open-minded, and having a positive attitude can only help grow your professional relationships — if you’re pleasant to work with, the more people will want to connect with you during the internship and beyond! If you know someone around the office who always brightens your day and reminds you to stay positive, show your appreciation with this cheerful watercolor card. It features a fun cutout design and is blank on the inside, so you can tell them personally how great they are!

Writing inspiration: “Thank you for being a positive inspiration on the busiest of days! You’ve made my internship experience unforgettable.”

For the fearless leader

We all know someone who embodies “fearless leader” energy, and this card is perfect for them! Whether you have a director or supervisor who’s adept at wrangling all of the interns, helping you execute projects on time, or lead the teams to victory, it can be powerful to thank them for their guidance. I love how the card is meaningful but cheeky, with the inside reading “thank you…for tolerating us!” This card might be ideal for a boss who takes their job seriously while still maintaining a sense of humor.  

Writing inspiration: “I don’t know how you do it, but you always lead us to victory. Thank you for being our fearless leader.”

For the coworker who makes you laugh

Thinking back to my first summer internship, I’ll never forget one teammate who, without fail, always made me laugh! I sent her a card one day to let her know how her positivity and humor impacted me, and I’ll never forget the look on her face when she read it — it absolutely made her day! If you want to grow lasting relationships at your internship this summer and know someone who always makes you smile, this fun card will be the perfect way to show them you care. Psst: take a peek at the funny note on the inside of this card, and chances are, you’ll know exactly who to send it to.

Writing inspiration: “Seriously, where would I be without you?! Thank you for always bringing a smile to my face. You’ve made this internship incredible.”

For the teammate who helped you out

One key lesson you’ll learn as an intern is that teamwork truly does make the dream work. It often takes a village to execute goals, both big and small, and this thank you card is a great way to thank a teammate who has gone the extra mile to help during your internship. The cute balloon design and colorful confetti is a fun way to celebrate teamwork, and I love how the inside message says, “Sometimes it takes a village. So glad for your helping hand.”

Writing inspiration: “Thank you for always going the extra mile to get the job done. I can’t imagine our team without you!”

For the one whose presence makes a difference 

During my first summer internship, I remember one coworker who was pretty shy around the office, but her kind presence made a huge difference in my internship experience. She always made me feel calm and grounded, and I made sure to tell her at the end of the internship term. Like this adorable card suggests, our world — and internships — are busy, but every thought, word, and act can make a difference. If you know someone who has made a difference for you this summer, be sure to share how you feel with a thoughtful card.

Writing inspiration: “Thank you so much for making the office such a warm and inviting place to be. I appreciate you!”

If there’s anything I’ve learned from doing multiple summer internships, it’s that relationships matter. From your rockstar boss to the coworker who made you feel welcome on that nerve-wracking first day, be sure to express your gratitude by sending a thoughtful card and ensuring that your relationships are built to last long after your internship term has ended. Sending a card may seem like a small gesture at first, but when it comes to networking and making a lasting impression, remember: cards do more.
