Meet Our Dental Team at Mark J. Niekrasz, DDS & Associates

Angelica Venegas – Office Administrator

Angelica has been with our team for 13 years. She is a very competent office administrator, handling appointments, billing, and insurance, as well as helping our Spanish-speaking patients feel right at home as she explains dental procedures and financing options. Angelica shares that the job has enhanced her ability to multitask and set goals. She likes working with our staff because, “together as a team we can be better at what we do – help patients achieve a great smile.” Dr. Niekrasz, Dr. Donovan, and Dr. Rosen, and Kathy so appreciate Angelica’s “can do” positive attitude toward all that is asked of her as office administrator. It is an expansive, important job and Angelica does it all with confidence and a smile. When Angelica is not working, she enjoys spending time with her husband and their three children.

Maria Mora – Assistant Office Administrator & Dental Assistant

Maria has been involved in the dental field for 13 years. She most enjoys her connection with patients as she makes appointments, answers insurance, and dental questions, and welcomes and encourages patients as they strive to achieve healthier and brighter smiles. Maria is generous with her welcoming smile and a deep knowledge of dental procedures. In 2014, Maria plans to attend college part-time to further her healthcare education.

Lucia Carlos – Office Facility Coordinator

Lucia has been working in the dental field for 2 years as part of our team. She is a natural organizer who maintains our office, operatories, and supplies with thoroughness and pride. Lucia also jumps in when needed to make appointments and record payments. Lucia says that since being part of our dental team, her communication skills have been enhanced. She enjoys working in our dental office because “everyone is friendly and hopeful.” When Lucia is not working, she and her husband together enjoy time with their three children.

Kathy Niekrasz – Senior Dental Assistant & Treatment Coordinator

As Dr. Niekrasz’s wife and longest-running employee, Kathy appreciates all aspects of the dental field. She most enjoys assisting in all dental procedures and educating and encouraging the patients as they work to achieve better dental and overall physical health. “We have patients who have been with us over 25 years and they are truly family to us.” Kathy helps make needed treatment understandable to our patients, and with Angelica’s and Maria’s expertise, she coordinates treatment costs with insurance benefits, co-pays, and financing. “When you break down into incremental, manageable steps what seemed overwhelming to the patient, treatment becomes doable. The patient can begin treatment with the necessary knowledge and assurance that a healthy smile can be achieved.” Everyone is a winner. That is the goal we as a dental team strive to achieve with each of our patients. When not working, Kathy enjoys spending time with her family, volunteering on local policy action organizations, and sewing and costuming for the School of Ballet Chicago. Dr. Niekrasz and Kathy have three adult children and two beautiful grandsons. Their oldest daughter is a dedicated nurse, wife, and mother of two. Their son is a published writer (MFA from the Writer’s Workshop, U. of Iowa) and musician. Their youngest daughter is a professional ballet dancer with Ballet Memphis. Kathy says, “The artistry in our three children comes mainly from their father. His artistic eye has been a tremendous asset in his dentistry, especially with achieving the best cosmetic outcomes with veneers, crowns, and dentures.”


Alicia has been in the dental assisting field for over 20 years. She brings a smile to all her patients and is very capable in her assisting and overall organizational skills. Alicia is fluent in both English and Spanish and is especially good in aiding communication between the doctor and the patient so that the patient’s needs and concerns are addressed in treatment planning. When Alicia is not assisting her doctors, she is home enjoying time and camping trips with her husband and growing son.
