🎉💜 Happy 1-Year Anniversary, Sabrina! 💜🎉

Sabrina is truly the glue that keeps us together. She is one of the hardest workers, always thoughtful, caring, and willing to jump in wherever she’s needed. She has the biggest heart and genuinely loves everyone she meets. 💕

And if you know Sabrina, you know she is also the BEST cook 👩‍🍳 and incredibly crafty! ✂️🎨 There’s pretty much nothing this girl can’t do!

We are SO lucky to have her on our team and can’t imagine SHN without her. Thank you for everything you do, Sabrina, and for bringing so much kindness, creativity, and love to our office every day.

Happy 1 Year, Sabrina! We love you! 💜🦷✨

💜 Saying goodbye to our summer intern, Clare! 💜

We’ve had the absolute BEST time having Clare with us all summer! 🥹✨ From day one, she was so sweet, eager to learn, and caught on to everything so quickly. She became such a wonderful part of our SHN family, and we truly loved having her here!!

Her time with us was filled with lots of learning, laughter, and so many fun moments. We’re so grateful for all the help she gave us at the office every day. 🦷💜

Now it’s time for Clare to head back to college! 🎓 We’re wishing her an amazing school year filled with new adventures, lots of success, and continued growth.

We’re going to miss you, Clare! 💜 Good luck at school — don’t forget about us! 😉✨
