Meet the Team

Holly Treadwell

Agent / Agency Owner

I have been a member of the Marietta community since 1991. I received my bachelor’s in business administration from the University of Alabama. Before moving back to our great state of Georgia, I left my mark in ‘Bama by being a founding member of the Business Honors Program.

I’ve been in the insurance industry since 2003, where I began by specializing in large Commercial Insurance. After many years of experience working with great carriers for Commercial and Personal Insurance, I started my own insurance agency in 2009, partnering with Nationwide Insurance. In the years since, I have expanded the agency to represent many insurance carriers specializing in commercial, personal, and life/annuity policies in three different communities, which I love very dearly.

I have always dreamed of creating a positive work environment where people enjoy working together, emphasize family, and truly care about our clients to advise better and protect them. I have a wonderful husband and two children I adore. We love to travel, music, sports, and enjoy life with family and friends. This is the environment we have cultivated here at Unify Insurance; we genuinely care about the people and communities in which we are located. We grow our genuine relationships with our clients through trust, expertise, and professionalism.

It is our pleasure to “Unify” your insurance needs!

Lindy Head

Agent / Operations Manager

Hi, I’m Lindy Head, and I’ve spent nearly 40 years serving clients across Marietta, Woodstock, and the surrounding Georgia communities. I grew up in Atlanta and Mableton and now live with my husband in Ellijay, GA, nestled in the North Georgia mountains. I’m a licensed insurance agent in property and casualty as well as life and health insurance.

Over my 39-year career, I’ve specialized in home and auto insurance, and for the last 12 years, I’ve focused on small business commercial insurance alongside personal coverage. I work primarily with families and small business owners, helping them protect what matters most while providing guidance they can trust. What excites me most about my work is being part of an amazing team of women who treat our clients like family and go above and beyond every day.

Outside the office, I’m a dedicated sports fan—cheering on the Atlanta Braves and the Georgia Bulldogs is a weekend ritual during football season. I also love tackling jigsaw puzzles, keeping one in progress at all times.

Serving clients in Marietta, Woodstock, and the surrounding areas for decades has been an incredible experience, and I’m passionate about delivering personalized insurance solutions with care, expertise, and a friendly touch.

Amy Wade

Agent / Marietta Office Manager

Hi, I’m Amy Wade, and I’ve proudly called Cobb County home my entire life. Based in Marietta, GA, I’ve had the privilege of serving our local community and surrounding areas in the insurance industry since 1988. I’m a Wheeler High School graduate and attended Kennesaw College before it became Kennesaw State University.

As the Office Manager at Unify Insurance, I specialize in auto and home insurance, with experience in commercial coverage and licensing in life and health insurance. I’m also proud to hold the CISR designation, which allows me to provide expert guidance and personalized solutions for families, seniors, and small business owners alike.

What I love most about my work is building strong relationships with my clients and helping them truly understand their coverage. I enjoy identifying gaps in protection, educating clients, and often saving them money while giving them greater peace of mind.

Outside of work, you’ll usually find me surrounded by family – my husband, three children and their spouses, and my beloved grandchildren, who truly are gifts from God. I enjoy trips to the beach and Disney, baking fresh treats (often using eggs from our backyard chickens!), and spending time with our two Bernedoodles and Yorkie. I also have a musical side, having sung regularly at church, and stay active in my faith through Christian retreats with Vida Nueva and Tres Dias.

I’m passionate about helping my neighbors in Marietta and Cobb County protect what matters most and providing guidance that’s both clear and caring.

Emily Newell

Agent / Blairsville Office Manager

A proud native of Blairsville, Georgia, I returned home in 2009 after spending several years living and traveling abroad, as well as time in Florida and Texas. I hold an MBA with a concentration in Cybersecurity, which allows me to approach insurance with a strong understanding of risk, protection, and long-term planning.

After many years in the automotive and financial industries, transitioning into insurance in 2016 was a natural progression. Since then, I’ve helped individuals and businesses clearly understand their risk exposures and feel confident in their coverage decisions. I work closely with each client to find the best possible solutions—whether for auto, home, commercial business, or liability insurance – always with the goal of protecting what matters most!

I believe insurance should be personal, proactive, and easy to understand. My approach is built on education, transparency, and long-term relationships.

When I’m not working, I enjoy spending time with my family and my fur babies, riding horses, and watching football. I’m also passionate about giving back to the community through active volunteer work with Relay for Life and Healing Hands Community Clinic, Inc.

Erin Warren

Licensed Customer Service Representative

Hi, I’m Erin Warren, a Customer Service Representative and licensed Property and Casualty Agent with Unify Insurance. I’ve been working in the insurance industry since 2002, starting my career in Southwest Florida and continuing my journey in the beautiful North Georgia mountains since 2006.

Over the past two decades, I’ve built my experience around customer service and personal insurance solutions. I specialize in property and casualty insurance, helping individuals and families secure reliable auto insurance, home insurance, renters insurance, and other personal coverage options designed to protect what matters most. I have been a Licensed Georgia Insurance Agent since 2010, and I take pride in staying knowledgeable so I can better serve our clients.

What excites me most about my work is getting to know our policyholders on a personal level. Insurance is never one size fits all. I enjoy taking the time to understand each client’s situation so I can tailor coverage that truly fits their needs, whether they are protecting their home, vehicle, or other valuable assets. Building long term relationships and being someone clients can trust is the most rewarding part of what I do.

Since moving to North Georgia in 2006, I’ve loved serving this community and continuing to grow in the industry. When I’m not at the office, you’ll likely find me at a concert enjoying great music or exploring museums and art exhibits. I appreciate creativity and connection, both in my personal life and in the relationships I build with our clients every day.
