Insurances accepted
Baylor Scott & White has established agreements with several types of insurance to ensure your health needs are covered.
Insurance listings are subject to change without prior notice.
Please call your physician's office or your health or insurance plan to verify coverage information prior to scheduling your visit or procedure. Not all members participating in contracted networks have "in network" access. In network participation may change from time to time without prior notice. Independent providers (which could include, for example only, anesthesiologists, radiologists, pathologists, emergency medicine physicians, advance practice professionals, and other independent providers of health care services) may deliver part of your care, and such providers may be considered out-of-network on your health and insurance plans even if the Facility may be considered in network. If you desire additional information as to the providers who may be involved in providing your care, you can either ask your treating provider (who may know some of the specialists or groups who could be involved) or you can request a list of Facility-based physician groups by calling the following toll free number: (877) 810-0372. This list is updated annually and is subject to change without prior notice.

Patients appreciate
Dr. Jennifer St. John receives overwhelmingly positive feedback from patients who consistently praise her thoroughness, knowledge, and excellent listening skills. Patients repeatedly describe her as professional, caring, and compassionate, noting that she takes time to explain complex medical information in understandable terms. Many reviewers highlight that she never rushes appointments and makes patients feel heard and respected. Her bedside manner is frequently commended, with patients appreciating her personable, friendly approach while maintaining professionalism. Patients particularly value that she involves them in treatment decisions, asks detailed questions, and remembers personal details from previous visits. Multiple reviews mention successful health outcomes under her care, including improved diabetes management and thyroid treatment. Her ability to work well with special needs patients and communicate directly with them rather than through caregivers is specifically noted as exceptional.
Patients also share
A small number of reviews indicate opportunities for improvement. One patient felt Dr. St. John was dismissive of their concerns and used a condescending tone, leading them to plan not to return. Another patient wished she would be more comprehensive in her approach. One reviewer mentioned difficulty connecting initially, though they noted the situation improved once connection was established. A few patients gave slightly lower ratings without detailed explanations, with one mentioning they wished for better communication that didn't feel like talking down to them. Wait times for appointments were mentioned as lengthy, with one patient noting it took approximately four months to get scheduled.
