I can’t imagine what Tammi’s family is feeling. Tammi was one of the true professionals I have had the pleasure to deal with over the years. So smart and loved what she did and working with the Gerrity family. As a supplier, she always treated me with kindness and respect. I will miss our spirited conversations and her knowledge. I am shocked and saddened beyond words. She will be missed by many more than me.

Tammi was such a kind-hearted person. One quote she often shared—and one that will always stay with me—is that she hoped we would all continue as one big Gerrity family, united in growth, success, and support for one another.
Walking into Tammi’s office, she always had a smile that lit up the room. Her warmth and kindness left a lasting impact on everyone around her. She will be truly missed.
Please accept my heartfelt condolences during this difficult time. I am deeply sorry for your loss. May you find strength in the love that surrounds you and peace in the meaningful memories you hold close.
As you grieve, may this verse bring you comfort:
“The Lord is close to the brokenhearted and saves those who are crushed in spirit.” – Psalm 34:18
My thoughts and prayers are with you and the entire family.
