Duane Siple

Office Manager and Quickbooks Pro Advisor

I graduated from University of North Texas with a prelaw degree in 1997 and Oral Roberts University with a Masters in Theology in 2009. My educational backgrounds were inspired by my desire to help people.

After graduating from North Texas, I served as an insurance and financial investment sales representative for a large nationwide insurance company. After a few years, I went to work as a retail sales representative with another national company and I was promoted to management within 6 months of service. After several years, I was employed with Apple Inc. in their Solutions Consultant program. While I was with Apple, I was responsible for training clients and employees, management communications with our host company. After obtaining my degree, I have been invited to teach small groups of young people in classroom setting.

My focus, regardless of my position or company, has always been in management and quality control. My role at KL Siple CPA PLLC is to provide our employees with an environment that promotes proper training and development. In addition, I oversee the firm's processes so that we provide our clients quality services. As a QuickBooks ProAdvisors, I can troubleshoot QuickBooks issues and assist in training staff and clients in the operations of QuickBooks. As an added benefit, I assist clients with their software purchase needs so that we can pass down any discounts savings to them.

Jeremiah Carter

My name is Jeremiah S. Carter. I may have been an unconventional choice for an E-file specialist for Kl Siple CPA, but ever since I’ve started working with this company it has brought so many opportunities. Before coming to work for the firm, I attended the University of Texas at Arlington. Afterward, I worked in the theater field as a Lighting and Sound Technician for four years. Although my previous working experiences have had little to do with Accounting, being a technician has helped me profusely within this career. Bringing the skills of my last occupation along with me, being detail-oriented and focused has helped me prosper within the environment and to myself as a professional.
