As a 35 year industry veteran and current President of Diamond Residential Mortgage Corporation (DRMC), my ultimate goal is building a best-in-class organization focused on “You,” whether “You” are a client, business partner, investor, or team member. At DRMC, we value our customer relationships. We pride ourselves in getting the job done and our “can-do” culture.

I began on the street as a loan officer in the early 80’s and rose to the ranks of executive management with major national mortgage players. Over the years, I have witnessed the real estate and mortgage lending industry change. The mortgage industry has moved away from recognizing the importance of great service and long-term market relationships. Many in the industry seem to forget that when the customer comes first, everything else will fall into place.

AT DRMC, people are our most important resource. We base our organization on trust – in each other and our customers. We will never compromise our ethics. We are building an organization of which we can be proud. Our goal, at all times, is to conduct business with the highest integrity and in a professional, customer-focused matter. We strive to have everyone with whom we work recommend our products and our services without reservation. We want to be known as the best in the class and as an asset in the communities in which we conduct business. It is not just a transaction; we care! The 35 years that I have been in the mortgage business has taught me that this business is built on trust, reputation, customer service, accountability and - most importantly - people. At DRMC You come first!

Over the past 25 years, I have learned the mortgage industry from the ground up. After beginning my career as an accountant, I joined Paul Diamond in the mortgage industry at Lumbermen’s Investment Corporation in 1986. In 1989, I assisted in the development of Centex Corporation’s “CTX Mortgage Company,” where I served as a Top Loan Officer, Sales Manager and later as Division Vice President.  While serving as Division Vice President of CTX Mortgage Company, I ran the most profitable division in Illinois. In 2004 I became the Regional Vice President of the State of Illinois for the Midwest District for First Magnus Financial Corporation, and in 2007 I joined forces with Flagstar Bank.  I served as the District Manager of the Illinois Group until 2009, and I assisted in the development of Diamond Residential Mortgage Corporation, where I am the currently Chief Financial Officer.  I am a very detailed and accomplished mortgage professional that truly understands all the inter-workings of the mortgage business.

I currently reside in Gurnee, IL with my wife Tracy and our four children.  We all are very active within our community.  I enjoy competing in Triathlons and have participated in the Hawaiian Ironman World Championships six times.

Hello, I am Diana Whitmire, the Chief Operations Officer at Diamond Residential Mortgage Corporation. I began my career in the mortgage industry in 1986 and have been with DRMC since its inception. Throughout my career, I’ve gained experience in all aspects of mortgage operations, having spent 35 years leading and managing operational teams. My hands-on understanding of Compliance naturally evolved from my time in operations. In late 2021, I transitioned into Senior Vice President of Compliance and Quality Control to expand my expertise in this highly regulated industry.

In my new role as Chief Operations Officer, I oversee the alignment of operations, compliance, and product development—including construction and renovation lending—to create seamless, efficient processes that benefit our team and our clients. I focus on ensuring every team member has the tools, knowledge, and support they need to succeed while upholding the highest quality and regulatory compliance standards.

I strive to contribute to the solution to every challenge while fostering an environment where everyone feels valued and appreciated. Together, we’re building a stronger DRMC to serve our clients and partners excellently.

I have over 40 years of experience in the Retail Mortgage Business to include experience in underwriting, capital markets, product development, production management and even personal production. I have owned 2 companies and have run production for 4 others, including CTX Mortgage, GMAC Mortgage, American Home Funding, Shea Financial and BOK Financial.

The defining point in any successful service-based organization is the internal value that is placed on its most important asset- its employees. Creation of a valued financial asset is the work of numerous skills and people within the mortgage process. Sales, Underwriting, IT, Processing, Loan Delivery, Secondary marketing, Finance and accounting, Audit, Quality control and many other disciplines must work in unity to create a sustainable, profitable company. All parties involved in the process are important and vital to the creation of a fungible asset.

DRMC is a dedicated and focused retail mortgage operation. At DRMC, every loan is important, and we dedicate each day to delivering on our promises and meeting your expectations. I am proud to be associated with one of those rare organizations that thoroughly appreciates the efforts of all of its employees.

The DNA of Diamond Residential is a focused company that really “Gets it”.

Over the past 20+ years, I have served as a Mortgage Consultant, a Sales Manager, and a Senior Division President. This experience has given me an extensive knowledge of the entire lending process from both a lender’s and administrator’s perspective.  In my current position as a Senior Division President I am back to doing what I love best:  working directly with clients and servicing their lending needs.

As one of the nation’s top FHA and VA Mortgage Originators, I am dedicated to making sure my customers are educated homebuyers. I provide credit and budget counseling and credit repair advice.  I also conduct homebuyer’s seminars throughout the year to make sure the community is informed on the constant changes in the mortgage industry and home buying process.  I am a Mortgage Product Specialist; I will always work to get you the best loan for your situation.  I consider it an honor to work with first time homebuyers, and I am well-versed in the numerous first time homebuyers’ programs.  Our products include Conventional, Jumbo loans, FHA, VA, LIBOR and Treasury ARMs, just to name a few.

I take each loan transaction personally. My team and I will work to ensure your mortgage transaction is smooth and efficient.  When my customers receive the keys to their new home, I feel blessed to share in their dream of home ownership! When I am not taking care of my customers, I am a dedicated wife and mother.  In my spare time, I enjoy reading, cooking, shopping, and interior decorating.  I am a woman of great faith which truly drives my commitment to my business and the community. If you choose to work with me, you will not be disappointed! Please call me for your purchase or refinance transaction today!

Hello! My name is Sandy Nommensen, and I am the Senior Vice President of Corporate Administration for DRMC. After many years of owning and operating a family business while working in the outside business sector with a concentration in payroll and HR, I was given the fantastic opportunity to join the Diamond family to serve in Corporate Administration in 2012, and it’s been a joy to call DRMC home ever since. 

Corporate Administration supports many aspects of corporate, from payroll, HR, and benefits to working closely with our CEO and CFO to ultimately support our employees. 

I am motivated by my faith and by the love of my Diamond family. I am often called one of the mothers of the Company. It is a privilege to serve such wonderful people. I am also very proud to be part of developing and implementing the Diamond Gem program and planning creative and unique Sales and Operations Conferences. 

My journey in the mortgage industry began in 1997 when I started as a loan officer with the added responsibility of training new loan officers. Over the years, I've gained extensive experience in various aspects of the mortgage process, including origination, processing, closing, and underwriting, which eventually led me to my current role at DRMC. As SVP of Operations, my key responsibilities revolve around providing strong leadership to our operations team and fostering a culture of collaboration and excellence between our operations and sales departments.

What truly motivates me is the opportunity to find solutions that benefit our clients and our organization. The mortgage industry can be challenging, but I find great reward in overcoming obstacles and helping individuals achieve their dreams of homeownership. I strive to embody the company's values with a can-do attitude every day. I firmly believe in leading by example and encouraging others to do the same. 

One of the proudest moments in my career was receiving the Best Mortgage Underwriter award from the IMBA, part of the Best in Biz Awards for 2018. This recognition serves as a testament to the hard work and dedication put forth by our entire team

I began my career as a staff attorney at a nonbank mortgage lender, where I worked my way up to Deputy General Counsel before leaving for a General Counsel position with DRMC.

I have been with Diamond since 2021,  and it’s been impressive to see the commitment to doing things the right way. I find what I do interesting, and I enjoy how the GC role allows me to work in both the legal and business spheres, managing the legal and compliance functions of the company while serving as a strategic advisor to management. I take great pride and satisfaction in enhancing compliance and legal processes at DRMC.

Hello, I'm Melissa Segura, the Senior Vice President of Mortgage Servicing at Diamond Residential Mortgage Corporation. I started in the mortgage industry in 1998 as a mortgage loan collector. Over the years, I've tackled everything from Compliance, Project Management, and Investor Relationship Management, which eventually led me to create and oversee the Subservicing initiative for Aurora Bank, FSB. In November 2016, I was thrilled to join the DRMC team entrusted with running the Mortgage Servicing division. 

As the SVP of Mortgage Servicing, I take pride in my responsibility for all Interim Servicing activity and the oversight of our Mortgage Subservicer. Ensuring compliance with investor and regulatory guidelines is essential to handling our customers' loans accurately and professionally, embodying the exceptional customer service that DRMC is known for. By preventing errors and inaccuracies, we create a seamless experience for our borrowers, encouraging them to return to DRMC for all their mortgage needs.  It is rewarding to know that my knowledge and experience contribute to an essential part of someone’s homebuying journey.

Since joining DRMC, I was instrumental in obtaining both Ginnie Mae and Freddie Mac Seller/Servicer approval, which added to the already approved Fannie Mae approval. This makes DRMC one of the few companies in the U.S. with all three GSEs' approval to sell and service loans with them.

I am very proud to represent Diamond Residential Mortgage Corporation. My goal is to provide you with the best customer experience possible, and I welcome the opportunity to guide you through the home loan process and help you select the loan program that best suits your needs.

My core belief that the customer is the number one priority sets me apart from my competition, and my philosophy is to listen to each customer’s needs and respond to them efficiently and effectively. Communication is the key to building strong and lasting relationships with borrowers and business partners alike.

In the time I have been in the mortgage business, I have gained the knowledge and expertise to help put my customers at ease throughout the mortgage process. My diverse experience in the mortgage industry allows me to better assist my clients and ensure a smooth process from origination to closing. It would be my pleasure to help you with your home financing!
