Get Familiar With The TDA Now Insurance Team

Mark Diederich

CEO

My name is Mark Diederich, I have owned the agency with my wife Sherry for the last 27 years. I try to treat others the way I would like to be treated. This is one thing I have been focused on throughout my career in serving clients. If you put yourself in others’ shoes, the probability of a positive outcome is very good. If we take care of our clients, everything else will take care of itself.

I currently serve as the CEO of the Agency. This keeps me involved in all aspects of the agency. I also actively work in our Financial Services Department as a Certified Financial Planner (CFP), assisting clients with their investments and planning.

I started my career with GMAC Insurance in 1987 after graduating from Central Michigan University. After several successful years in the corporate world, I had a desire to exercise my entrepreneurial spirit. Looking for opportunities to start my own business, it only made sense to use my background in Insurance. I started my first agency with Nationwide Insurance in 1996. I rapidly grew my agency from no clients to many. As we went through some market cycles, it became clear that representing only one company was not in the best interest of my clients. In 2010, we made a tough decision to resign from Nationwide and start a scratch independent agency. That was the right decision for us, and our clients, and we have been on an upward trajectory ever since.

Understanding that knowledge is a powerful ally, I continued my education completing my MBA from the University of Detroit in 1990. Since then, I have secured my Certified Financial Planner (CFP), Charter Property Casualty Underwriter (CPCU), and Life Underwriter Training Council Fellow (LUTCF) designations.

I grew up in Dearborn Heights, MI and have been in the area my whole life. I have been married to my business partner Sherry for 27 years. We have two awesome adult children, Dan, and Matthew, who also share the passion for helping others and have joined the Agency to take it to the second generation.
In my limited spare time, I enjoyed coaching youth sports, playing golf and spending time with family and friends.

Sherry Diederich

President

My mane is Sherry Diederich, President, and Agency Principal at TDA. I have been working as an insurance agent for 27+ years, since my husband, Mark, and I opened the agency in 1996. I earned my bachelor’s degree and started working at GM after graduating. I worked in their licensing department selling the dealership’s insurance. In my career at GM, I ended up supervising a call center for MIC General (GM’s auto and home insurance company for their employees). I met my husband, Mark, while working at GM.

What I love most about working at TDA is the people – our employees, our clients, and our relationship with our carriers. We treat our employees and our clients like family at TDA. My family is everything to me. My husband, Mark, and my two sons, Danny, and Matthew are my world. Some of my hobbies and interests include golfing, cooking, spending time in my pool, and flowers. Something many people may not know about me is that I have a twin.

Dan Diederich

VP of Marketing & Property and Casualty Lines

My name is Dan Diederich, I am the oldest son of our agency owners, Mark, and Sherry. Ever since I was a little kid, I have grown up in the office and around the insurance industry. I have developed a deep passion for protecting peoples’ families, businesses, and assets through insurance products, and being dependable and reliable for people when they need it most.

I got both my property and casualty and life and health insurance licenses shortly after turning 18. I have also gone on to earn my Certified Insurance Counselor (CIC) and Certified Authority in Workman's Compensation (CAWC) insurance designations, that have given me additional training and coverage knowledge to better serve our clients. I am a huge sports fanatic, so I treat my career education like I treat practice and try to focus on getting a little better and learning something new every day, which is easy to do in this industry.

Currently, I oversee our property and casualty division at the agency, and have a strong focus on marketing and sales, which is what I concentrated on in my studies at Aquinas College in Grand Rapids, MI.

Aquinas is where I met my current fiancé, Remington, on a study abroad trip to Costa Rica after my junior year, and we have been together ever since. I played lacrosse and she played tennis there, and we both continue to have a great passion for sports and travel. Outside of work and travel, I spend most of my time playing sports or coaching JV White Lacrosse with my brother, Matt, at our high school alma mater, Detroit Catholic Central.

Matt and I work hard every day to try to build on the great foundation that our parents have built for our agency. Family is a very important value to us, and our motto is that we treat our employees like family, so they will treat our clients like family, and as a whole TDA family we can make a positive impact on the communities we serve.

I have my P/C license as well as a life and health insurance license. I have been exposed to the insurance industry throughout my childhood and have seen the positive impact that insurance products can have on helping people when they need it most.

I went into the industry because I have seen first-hand how rewarding it can be to assist people during challenging times, like when a claim occurs. I like working in the insurance industry because insurance provides financial protection and peace of mind to individuals, families, and businesses. I love being able to help people when they need it most, and the best part about working at TDA is that we treat everyone like they are part of the family.

I was born and raised in Novi, Michigan. I love the community here and it is a big part of why I love helping people. I recently moved into a house in Wolverine Lake with my girlfriend, Haydin, and my golden retriever, Bogi. In my free time, I love playing sports, spending time with loved ones, and being outside. I am in a softball, volleyball, and basketball league. I also am an assistant coach for the JV white lacrosse team at Detroit Catholic Central high school. When I am not playing sports, I usually am out on the lake or enjoying some quality time with friends and family.
