About Us

Custom Data Services, Inc. first opened its doors for business in November of 1973. Since its inception as a Medical Billing Service Bureau, we continued to expand the services that we provide as well as our client base. Custom Data Services, Inc. has expanded throughout the years to provide a variety of solutions to help its clients effectively manage and improve their office productivity.

The original founders of Custom Data Services, Inc. were Robert E. Swartz, Chris Retson and Robert F. Lindholm. These three gentlemen were CPA's in the firm of Swartz, Retson, Lindholm and Kettas, Inc. This firm was founded in Gary Indiana in early 1920. They continue in business today as Swartz, Retson and Company. The vision of these gentlemen was to develop a medical billing company to service the local physicians. Their expertise in accounting controls helped in developing the kernel for the proprietary software system that we use for our clients today.

In 1975, our current president Larry A. Mlynarcik joined Custom Data Services, Inc. as a computer programming professional. In 1981, Mr. Mlynarcik assumed the presidency of the corporation. At this time, Robert Lindholm, the managing partner retired.

In 1976, our current vice president Juan A. Arroyo joined Custom Data Services, Inc. as a computer programming professional. Mr. Arroyo became vice president of the corporation in 1985.

Currently, Custom Data Services, Inc. is owned and operated by Larry A. Mlynarcik and Juan A. Arroyo.

During the past thirty years we have developed a unique proprietary billing system that allows our clients a customized service that meets their individual needs. Through the use of this proprietary system, the client can select the correct level of service they need to run their practice efficiently.
