Meet William F. Cox, MD


My name is Dr. William F. Cox, and I would like to welcome you to my MDVIP-affiliated practice. Many of my patients do not know this about me, but I felt the calling to become a doctor at the age of five. In fact, I made it clear to everyone in my family by placing a sign on my bedroom door that stated, “Dr. William F. Cox,” in case anyone was in doubt.
 
My personal philosophy as an internal medicine physician has always been “patient first” with the goal of treating current health issues and, just as important, preventing new ones. I have always strived to offer a personalized approach to health care and, being in partnership with MDVIP, will help me to continue with this approach. 
 
I am affiliated with Texas Health Presbyterian Hospital of Dallas which has a history of more than 50 years of excellence in health care. My practice is made up of patients with a variety of health care needs – from patients preparing for their next triathlon to older patients trying to live longer lives with a better quality of life as the aging process takes place. I also take care of hearing impaired patients. Good health and wellness mean different things to different patients. To some, it means weight loss for preventing or controlling diabetes, improving nutrition and finding a workable exercise program to reduce cardiovascular risk, and to others, it means smoking cessation or receiving assistance and education for the care of aging parents. 
 
While my practice is located in North Dallas, I see patients from a variety of locations – from the Plano-Frisco-Allen area to DeSoto, Cedar Hill and Grand Prairie. During my 22 years of practice I have been very fortunate to develop good relationships with many medical and surgical specialists in the area. I have found these relationships vital as a primary care internal medicine physician.
 
My affiliation with MDVIP will allow me to continue my “patient first” policy as we navigate the craziness of health care. I love caring for my patients and being able to provide them with optimal care is my number one priority. My affiliation with MDVIP will help me to continue this for years to come.

Frequently Asked Questions

Doctors who operate in the MDVIP models typically see far fewer patients than traditional primary care doctors. That gives them more time to develop deeper doctor-patient relationships that can lead to better outcomes. They can also offer conveniences that most primary care doctors can’t, including same- and next-day appointments. They’re available after hours for urgent matters. And they have time to focus on prevention. That focus begins with the MDVIP Wellness Program, which patients pay for with their annual membership fee.

Most MDVIP-affiliated primary care practices accept insurance (your physician can tell you whether they accept your specific insurance plan). Your annual fee pays for preventive care medical services that insurance usually doesn’t cover (e.g., advanced diagnostic testing and screenings). Your MDVIP-affiliated physician will continue to bill your insurance and charge copays, co-insurances and deductibles as he or she currently does for other medical services like sick visits.

MDVIP makes wellness and prevention easier by providing your physician with innovative tools and technology. MDVIP supports your physician’s practice and seeks to eliminate barriers to a positive healthcare experience. Your doctor will determine whether and how to incorporate these tools at his/her discretion.

This is an excellent internal medicine doctor, and his practice is top notch. The office is calm, organized and professional. My husband and I never feel rushed. Dr. Cox is extremely thorough and conscientious. Both Dr. Cox and Nurse Bianca are intelligent and caring medical professionals. They also both keep up with a large breadth of research.

Dr. William Cox and his staff (especially Bianca) are extremely professional and are taking wonderful care of me, my husband and 91 y/o mother! Dr. Cox ensures that we focus on maintaining good health and staying on top of any issues that arise. He stays on top of the research related to not only our current issues, but also any potential medical issues.

Whenever I was asked “who is your primary physician?” - I never had a great answer. I didn’t have a doctor I consistently saw and went back to. I am happy to say I now answer “Dr. William Cox.” He is personable, honest, extremely knowledgeable and does what any doctor should - give you the information you need to live a healthier life. I recently completed my first annual physical (much more thorough than any other I’ve done) and it was the most comprehensive and beneficial thing I’ve done for my health. I can’t recommend Dr. Cox enough and am lucky my wife found him.

I am in awe of Dr. Cox. When I began in his practice I had some scary test results from an insurance physical. It had happened a few months before. I finally showed them to him. His response was calm but certain. He insisted that we check them out and suggested the kindest and best specialists. He has followed all the test results. His office feels like a warm caring living room. His entire office and staff feel like caring family. His wife is his RN, and provides an additional level of warmth and caring. He has been reassuring and encouraging about me continuing with these specialists. I quickly encouraged my husband to join his practice. He is a fabulous and caring physician.

As a healthcare executive and business owner with over three decades of experience, I have had the privilege of working with a countless number of physicians.

Currently, I am a patient of Dr. Cox through his concierge practice. In all my years of experience, both personal and professional, I have not encountered a more exceptional physician. Dr. Cox's intelligence, knowledge, and diligence are matched only by his bedside manner and caring nature. He is, without a doubt, the best primary care physician I have ever had.

If you are seeking an outstanding physician, look no further. Dr. Cox is the epitome of medical excellence.

I am both grateful and honored to have Dr. Cox as my concierge physician.

I highly recommend Dr. Cox without reservation.

Dr Cox has been my primary care doctor for several years. When I was looking for an Internist, My friend recommended Dr Cox to me. Through the years I have found that he is the only doctor I have had that truly CARES about me, physically emotionally and mentally. Dr Cox treats the whole person. He knows that by treating the whole person, he can get to the bottom of mini of physical problems easier. I have really bad arthritis and it hurts every joint replacement surgeries. I am also 72 years old and occasionally fall. Dr Cox has worked with me to discuss several ways I can limit my falling and be more careful. I have had bad arthritis and joint replacement surgeries and have had to be referred two other specialists. Dr Cox has referred me to a specialist in the area of upper body orthopedics, foot and ankle orthopedics, back surgeons and even a psychologist when I felt I was depressed. I can’t put into words what Dr Cox means to me. I just know that out of all the doctors I’ve had in my life, Dr Cox is the most compassionate and knowledgeable doctor. MDVIP is an excellent organization and have the best doctors in Dallas! Another wonderful thing about Dr Cox is the fact that when you go to him you never ever feel rushed or hurried. He takes his time with you to get to the bottom of the problem and when I am there I feel like I am the only person in the office! I can’t say enough about this wonderful man! His Office staff is also number one and they are very helpful when I call. I have referred several of my friends and family to Dr Cox because I feel like they will get the best care possible going to him.The best decision I’ve ever made in my life was to choose Dr Cox as my primary doctor. I will never leave his practice!

There is no internist who is as kind, caring, compassionate, knowledgeable, competent, and thorough as Dr William Cox. I highly recommend him to all my friends and family. He has quickly responded to me, my husband, and son anytime we attempt to reach him. He visits us while in the hospital even when he’s not the doctor in charge. He cares deeply for his patients. He assisted my son over the phone during a Type 1 diabetic crisis of an out of town friend. He guided them on actions to take and calmed all their fears. The friend is only 22 and was visiting from CA. He guided me through a sudden blood pressure drop of my husband after surgery, and with his knowledge and assistance, we remained calm and leveled his BP at home. Dr William Cox is simply amazing! We are so very grateful to have him and his expertise in our lives. He gives us a huge sense of comfort, guidance and calm in any crisis so we don’t needlessly call 911. On the flip side, there was a time when he instructed us to go to the ER which resulted in a 3 day hospital stay. He is always SPOT ON in his advice. We appreciate him so much!

Dr Cox has been my primary doctor for around 9 or 10 years and i kept telling my wife about him because I think he is very caring and knowledgeable and I have never asked him a question that he ignored. Well my wife finally had a medical emergency and I called Dr Cox's office and scheduled an appointment for her and he worked her in that very day and she needed a CT scan which he arranged for her immediately and the next day he had the diagnosis which was not what we wanted to hear but we were amazed at how quickly he called her back. She wrote an old fashioned letter of thanks. Since she has never done a google review, I am typing and posting the handwritten letter to Dr William Cos for her: "Thank you! You are the first medical doctor I have had in many years who actually listened and really heard what i was trying to communicate. You were quick to respond with knowledgeable answers and action that brought quick diagnosis and a treatment plan. I am so glad Jim brought me to see you Wednesday when I was in so much pain. So grateful to call you, "my doctor" Looking forward to many successful years working together for good health. "

He recorded all of our previous and present specialists in order to get our past medical history and answered all our questions and concerns about having to change doctors. We have been extremely happy with Dr. Cox who showed us that he cared for our welfare and health.

After almost 3 years during COVID, I went to Dr. Cox for a physical. It was August, 2023. I thought the appointment would be positive, as I had lost 20 pounds abstaining from sugar and beer. At 5'8" I was still heavy at 187, but off my peak of 207 in 2020. A week after my blood draws, I went in for my "good boy" appointment. The first thing Dr. Cox told me was that I was Read more...
