    I am a nephrologist at Duke University with over 20 years of experience as a clinician, clinical researcher, and mentor. In my outpatient practice, I take care of patients with chronic kidney disease (CKD). In my hospital work, I evaluate and care for patients with acute kidney injury and with electrolyte disorders. In clinical research, I am experienced in serving on steering committees for multicenter clinical trials in CKD, including work with National Institutes of Health (NIH)-funded trials -- the African American Study of Kidney Disease and Hypertension (AASK), the AASK Cohort Study, the Dialysis Access Consortium, and the Focal Segmental Glomerulosclerosis (FSGS) treatment trial. I recently joined the steering committee for the NIDDK consortium, pilot studies of candidate therapies for CKD. I am active in multiple industry-sponsored clinical trials. I am a member of the executive committee for the Collaborative Study Group, a consortium that has implemented several successful clinical trials in nephrology.

My niche is taking care of pregnant women with kidney diseases and hypertension, as well as complicated hypertension, chronic kidney disease, and dialysis in the hospital setting.

The kidney center here at Duke is nationally well-known, and we see patients from all over, including international patients. I always want my patients to know I am available for them, either through MyChart or if they call the office and ask a question; they'll usually get an answer within 24 hours.

    I knew from an early age that I wanted to be a primary care physician like my grandfather. His passion for his work is one that I now share. I firmly believe in the importance of prevention and make every effort I can to engage my patients before they become ill, so they can remain happy and healthy members of their communities. I feel honored that my patients have chosen me to serve as their primary care physician. It is a privilege to share in people’s experiences, especially when they are feeling most vulnerable. When I'm not practicing medicine, I am trying to soak up every moment I can get with my wonderful wife and two incredible kids. I also love music and play the banjo, piano, and cello.

    "A.T. Still, MD, the founder of osteopathic medicine, once said, ""To find health should be the object of the doctor. Anyone can find disease."" From my early days in medical school, I was taught to look at the whole person, meaning that I see each patient as more than just a collection of parts that may become injured or disease. This holistic approach taught me how to integrate the patient into the health care process as a partner. This basic foundation was expanded upon as I completed both my residence and fellowship at Duke. I like to think that in the years I have been practicing medicine, I have honored those words spoken by Dr. Still. As a board certified family physician, I have sought to promote wellness and wellbeing among my patients at all stages of their lives, through collaborative partnerships with them (and sometimes their caregivers) in what I believe is truly patient-centered care. I look forward to working with you or your loved one in the future. Together, we can find health.".

    I am originally from Pittsburgh, Pennsylvania. I joined the US Army at the urging of a fellow classmate in medical school. Through the Army's Health Professions Scholarship Program, I completed medical school in New England.  I did my residency at a large Army base located in the Puget Sound area of the State of Washington, Fort Lewis.  I served 13 years in the Army and resigned my commission as a LTC in pursuit of working part time to spend more time with my family. I worked as a hospitalist at Duke for six years before returning to my true passion in 2016, primary care. I really enjoy making long lasting relationships with patients. I strive to give patients my best advice and through shared decision-making help them navigate their health care journey while keeping their life journey at the forefront of our minds.

    What is the definition of High Potassium Level?

    A high potassium level is a problem in which the amount of potassium in the blood is higher than normal. The medical name of this condition is hyperkalemia.

    When should I see a High Potassium Level doctor near Durham, NC?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing a High Potassium Level doctor near Durham, NC?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

    How does MediFind rank High Potassium Level doctors near Durham, NC?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by High Potassium Level doctors near Durham, NC?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with a High Potassium Level doctor near Durham, NC?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the High Potassium Level doctor search results page. 

    Why is it important to get a second opinion from a different High Potassium Level doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with a High Potassium Level doctor near Durham, NC?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my High Potassium Level doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my High Potassium Level doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

    Can I filter my search to show male or female High Potassium Level doctors near Durham, NC?

    Look for the filter feature on the left side of the High Potassium Level doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

    Can I filter my search to find a High Potassium Level doctor that offers video calls?

    Look for the filter feature on the left-side of the High Potassium Level doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
