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. John Mercer consistently receives exceptional praise for his compassionate, patient-centered approach to care. Patients overwhelmingly highlight his willingness to listen attentively without rushing appointments, taking time to thoroughly understand their concerns and answer all questions. His excellent bedside manner, warm personality, and genuine care for patients are mentioned repeatedly, with many noting he makes them feel comfortable discussing any health issue. Patients appreciate that he explains diagnoses and treatment options clearly in understandable terms, never pushes unwanted treatments, and involves them as partners in healthcare decisions. His knowledge, professionalism, and thorough examinations earn consistent trust, with numerous patients stating he's the best doctor they've ever had. Many families have used Dr. Mercer for years or even decades, with some patients driving significant distances—up to 90 miles—to continue seeing him. The office staff and nurses also receive frequent praise for being friendly, helpful, and professional.
Patients also share
Very few concerns appear in the reviews. One patient mentioned occasional wait times of about 15 minutes past appointment time, though they noted understanding this was due to Dr. Mercer's conscientious patient care. Another review referenced frustration with the BSW website system for scheduling and communication, though this was clearly directed at the healthcare system rather than Dr. Mercer himself. One patient noted the office staff seemed distracted on a particular visit. A single reviewer mentioned Dr. Mercer is not accepting new patients, which several others confirmed as a disappointment when trying to refer friends and family.
