“Dina, Tom has been a godsend. He has helped me handle daily crises and has given input that has been extremely useful in calming a potentially volatile situation. His experience and knowledge is invaluable. He took his time to really assess and understand our practice over the last month and now as he fully appreciates the issues, he has suggested changes in the schedule and space utilization that should help with the bottlenecks, and increase our productivity as well as enhance the waiting room experience for the patients.


He also has provided specific guidelines about what I, as a practice owner, need to do to successfully integrate our practice manager into the command structure of the practice and fully utilize her skills and expertise. He has provided me with introductions to other professionals and services that have been very helpful for our current and future needs.


And lastly I must let you know that he successfully renegotiated pricing of both our billing service and electronic medical record that will more than make up for the cost of your consulting services over the next year . He did this after my last OM had been unsuccessful in this endeavor. Thank you so very much.”

Paula S. Vogel, M.D. — Skin Specialists of San Antonio

“I have worked with Dina since 2012. She is very knowledgeable in all aspects of healthcare and business. She has put together an amazing team of professionals at Concordis. Our business is set up for success thanks to her!


I definitely recommend her company to anyone looking to start their own business. From employee hiring, to billing/coding or OSHA and HIPAA; she is the expert! The best part is that if she doesn’t know the answer she will do the research and come back to you with your options.”

Lynn Guion — Practice Manager

“It is with sincere pleasure that I take a few moments today to let you know how happy I am with your services and all your help in getting my five new physicians pushed through the initial credentialing process in such short order. When we made the decision to grow our practice by one-third in a short six-month window, and open two new locations to accommodate this growth, I was very concerned about how we were going to get these new staff physicians ready to go on the plethora of insurance plans we accept at our busy pediatric practice.


I have been amazed and very pleased with how quickly and efficiently you have completed this process, and how competent and professional you have been during the entire process. I simply could not have done it without you. I would not hesitate to recommend you and your team to anyone who is interested in doing business with knowledgeable professionals who know how to get the job done.


I hope that our practice finds lots of opportunity to work with Concordis in the future. You make my job so much easier!”

“Tom Tidwell is very experienced and was a great help and asset to my company during a transitional time between practice administrators. He did a great job searching for and screening candidates for the practice administrator position and was very helpful working as our interim administrator. Thank you Tom.”

Katie Tisdall, M.D. — Dermatology San Antonio

“We here at Spine Center of Texas have done two contracts with Concordis Practice Management. Dina was very helpful beyond expectations in assisting us in setting up our physicians contracts with Medicaid. Dina regularly sent me updated emails of the process it took and we felt that it was handled in a timely fashion. She was easy to communicate with. Because of the quality of Concordis Practice Management services, the support and most importantly the results, we are committed to using them for any additional physicians that come on board with Spine Center of Texas. It has been one of our best experiences. Thank you.”

Sabrina Kugler, Office Manager — Spine Center of Texas

I am writing this letter to thank you for the services that Concordis has provided to my family practice medical office. It has been a relief that a busy medical office can survive the sudden departure of a long time office manager.


Both Dina Petrutsas and Tom Tidwell were very reassuring from the beginning and your promise of “full-service medical management” has been kept. Not only did your team help train my new office manager but you have provided help with new staff, payroll, daily operations, budgeting and optimizing revenue stream. It is also nice to know that you will provide any services that my office might require in the future on an as-needed basis.


As you already know, most solo practitioners and small medical offices are not aware that a company like Concordis is available to help with the above mentioned services. Please do not hesitate to use me as a reference. Once again, thank you for your excellent service!

Victor D. Vela, M.D.

As a physician in San Antonio for 33 years finding quality trained employees has always been difficult and time consuming.  My medical group was recently looking for an assistant administrator that needed to have certain qualifications and training so we contacted Concordis.


They did a fantastic job of locating someone who had all the skills we felt we needed for this particular job. They were very thorough from the beginning. They met personally with us and came up with a very detailed job description. As they found candidates they interviewed them both on the phone and in person, and documented all the questions and their answers. Once a candidate was located that fit our needs we interviewed him. They took care of confirming his education, references and background check and offer letter. All of this was done quickly and professionally. We will definitely contact them in the future as we need to find new employees.
