A big THANK YOU to Lynda Sunderland for organizing collection boxes to help Shower Power.

Also, a SHOUT OUT to Darline Robinson’s friend, Jeff, who picked everything up and delivered it all to Shower Power.

THANK YOU to all our staff who donated clothes and shoes, water, gatorade, snacks, towels, deodorant, razors, socks and underwear to help the homeless in Jackson.

Skipping a daily shower is an inconvenience for most. For our unhoused neighbors in Jackson, access to clean water is a daily struggle. At Shower Power, they believe everyone deserves the basic dignity of being clean. They want to help restore dignity and hope, one shower at a time. Follow them on Facebook where they post items they need to help this ministry.

We shut our office down for our recent Spring quarterly Mission Trip Day. We ate breakfast together while listening to our guest speaker, Amy Lancaster, who shared several nuggets of wisdom.

We did one Skittle Scatter team building game where they competed for time off benefits. We always want to remind people about the importance of teamwork at work, home, church, etc. — “People who work together will win, whether it be against complex football defenses or the problems of modern society.” ~Vince Lombardi

Our community service project was working on the line in the warehouse at MS Food Network boxing up food for needy families. The whole group worked super hard to fill up several pallets with 50 boxes of food on each one - great job team!

We ate lunch together at Taste Italian Kitchen to honor Aaron for his 15 years of service on the P&T Team. They say eating and sharing meals with others is essential for building deep social bonds, improving mental well-bring and strengthening community trust. Studies show that communal dining acts as a powerful bonding tool that reduces loneliness, increases happiness and can even promote healthier eating habits. It offers a space for nurturing relationships and providing emotional support. We’re so busy at work, and it’s always a great opportunity to visit with different people on the team to see what’s going on in their personal lives.

We welcomed our four new people who were recently added to the team (Antonio White, Allison Neal, Nehemiah Jones and Harrison Fuller). We gave away two bonuses with an award. We ended our day giving out Mission Trip Day Bonuses. We greatly appreciate our whole P&T Family working together to fulfill our Mission Statement of Making Money To Spread The Gospel - As We Protect Life & Property - With Teamwork & A Spirit Of Excellence.

Our staff works hard and even more so when people are out sick or on vacation or simply dealing with family emergencies, so these mission trip days give everyone an opportunity to slow down and have a change of pace while giving back to our community. Slowing down to make time for what matters — including giving back — requires shifting from a reactive “busy” mindset to an intentional one, where you plan experiences like this and focus on presence rather than productivity. By breaking routines and deliberately choosing how to spend your time, you can create a more fulfilling life.

Jim Collette was the winner of our quarterly award with bonus. We have a great P&T Team, and we like to reward people for their hard work, dedication, great customer service, good attendance, etc. Our most recent award was the Bravo Award.

The Spotlight’s On You Jim!  From the opening act to the final bow, it takes the entire cast to deliver a show-stopping performance.  At a moment’s notice, we can count on our team to step in to ensure the curtain is always open to success and new opportunities.  Thanks to you (Jim) and the rest of the crew, great teamwork is the true star of our show.  BRAVO! 

Thank you Jim for all your hard work as an Alarm Technician who handles a variety of different service calls! You are greatly appreciated for the contributions you make to help the P&T Team succeed. Enjoy your Bravo Award and Bonus!

Shellie Norman was our most recent quarterly winner of the Shout Out Bonus. She processes a lot of calls and takes such good care of all our fire & commercial accounts and oversees the on-call schedule.

We like to celebrate and acknowledge the achievements of the members of our P&T Family. Part of our Mission Statement is Spirit Of Excellence. Having a spirit of excellence means you recognize other’s achievements. We tell our staff that it’s nice to hear the good stuff and not just problems. We so appreciate our staff taking the time to shout out when others do something good.

Thank you Shellie for going the extra mile to make sure we’re made aware of people on the P&T Team doing great things and getting compliments from customers. Enjoy your Shout Out Bonus!

Finding and recognizing people doing good things is crucial for fostering a positive, compassionate and resilient society. Research shows that actively seeking out and highlighting acts of kindness and competence — often referred to as “catching people doing things right” — counteracts negativity bias, builds trust and inspires others to replicate positive behaviors.

Our recent community service project was MS Food Network boxing up food for needy families. It’s hard work filling all the boxes, but our group just loves helping MS Food Network.

MS Food Network’s mission is to relieve poverty-related hunger in their service area by distributing donated and purchased food and grocery products through a network of member churches and nonprofit organizations and have been feeding Mississippians since 1984. We know they’re providing a valuable service with the rising costs of groceries.

A big THANK YOU goes to all of our staff who worked together as a team to get the job done. We filled up several pallets with 50 boxes on each pallet in a short period of time.

Aaron Grantham’s 15-year anniversary was February 7, 2026, but we celebrated a few weeks later. He picked Taste Italian Kitchen for his anniversary luncheon. Aaron was showered with gifts, a cake and lots of kind words.

Aaron does fire alarm quotes, inspections, installs and service as well as burglar alarm installs and challenging takeovers, etc. He also helps train new technicians.

Aaron, we hope you enjoyed your anniversary bonus. Thanks for all your hard work and perseverance over the last fifteen years. We truly appreciate all the contributions you’ve made to the success of the P&T Team. Congratulations on this accomplishment in longevity!

During our quarterly Spring Mission Trip Day, we had a guest speaker encourage our staff. Thank you Amy Lancaster for sharing what God put on your heart! She’s the co-founder of We Will Go Ministries with her husband, David Lancaster, and they do an amazing work on Farish Street in downtown Jackson.

Here’s an overview of what she shared:

God doesn’t waste anything. Don’t quit. Don’t give into temptation. Love God, and love your neighbor. You can’t fix everything. There’s only one Savior, and it ain’t you. You can’t do everything, but you can do something. If you listen, you’ll learn something. Don’t quit on people who are hard. You’re made in the image of God. Be used by Him. Don’t miss it. Don’t give up on problem people. Life isn’t easy, but be faithful. She quoted Isaiah 6.
