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

I am a native Georgian, born and raised in metro Atlanta! I have been in the insurance industry since 1987 and love my time working at Unify Insurance. I enjoy advising my customers and truly appreciate the team I have the privilege of working with daily.

I don’t just have a love for insurance; I have been married to my high school sweetheart for 42 years, who I love very much (even more than insurance)! We have four children who have blessed us with four beautiful grandchildren. I am also passionate about baseball. Not only did I coach for many years, but I also love rooting on our beloved Atlanta Braves!

What can I say? I have a lot of love to give! But working every day to “Unify” all my client’s insurance needs and doing it with such an amazing team… I could not be happier to share the love.

Amy Wade

Agent / Marietta Office Manager

I started my insurance career in 1988. I had worked at the same agency for 30 years before joining the Unify Insurance team in 2018. What a great decision that was!

I take great pride in treating my clients with care and kindness, and this isn’t just the standard at our agency- it’s the culture! There is great satisfaction in offering people savings on their current insurance rates and meeting all their needs. I’m incredibly grateful I get to do just this for my career.

Outside of insurance, I am proud to be a part of a beautiful family. I have been married to my husband for 35 years, and we now have three adult children, one of which has gifted us with two precious grandchildren! You can catch me spending time with my family and friends when I’m not at the office. I also love to bake, and quite honestly, a day at the beach is my own personal heaven on earth!

Emily Newell

Agent / Blairsville Office Manager

I am a native of Blairsville, GA. I traveled abroad for several years and then spent time in Florida and Texas before returning to Blairsville in 2009.


After many years in the auto and financial field, it was a natural transition to the insurance industry in 2016. Since then, I have helped many clients understand their risk exposures. My personal goal has been to help each person find the best possible coverage, whether in auto, home, commercial business, or liability.


In my free time, I enjoy being with my family and my fur babies, riding horses, and watching volleyball. I actively volunteer with Relay for Life and Walmart’s Fight Hunger Spark Change.

Stephanie Buquoi

Agent / Peachtree City Office Manager

My insurance career began in 1999, and I joined Holly’s team at Unify Insurance in 2016. I have experience working with several agencies and carriers and have gained so much insight over the years on how to best advise and protect my clients. I truly love and am passionate about finding the best coverage for a client’s needs.

In my spare time, I enjoy traveling, attending concerts, and spending time with my family. I married my high school sweetheart 24 years ago, and together we have three beautiful daughters. Recently, I became a first-time “Nana” to the most adorable grandson ever!

Erin Warren

Agent / Customer Service Representative

I’m an experienced insurance agent who started in the personal insurance industry in 2002. I began in Southwest Florida but had the opportunity to move to the North Georgia mountains in 2006, where I have continued to expand my knowledge in many lines of the insurance business. I have a passion for insurance and get great enjoyment out of listening to my clients to help provide tailored insurance policies that truly meet their specific needs.

My side passion is to draw and paint while listening to good music. I also enjoy venturing out with my husband to go to concerts, art exhibits, and science and history museums. I love spending time with my family and my two adorable dogs!

Ellen Weinberger

Agent / Customer Service Representative

I started my insurance career in 1992. After moving into personal lines underwriting for a specialty auto carrier, I realized how much I missed the everyday interaction with a team and clients, so I moved back to the agency level, where I have remained until now. I love spending my weekdays with the great team here at Unify Insurance!

Outside the office, I love spending time with my husband, four children, five grandchildren, and my great-grandchild! I also enjoy quilting, reading, and semi-retirement.
