    Philosophy of care | I will treat you as I would like to be treated in your place, and strongly believe in providing individualized care. A physician should clearly explain each patient's condition and the pros and cons of available options at the time of diagnosis and at each step along the way. Equally important is listening to patients to learn what is important to them and their concerns. | Why I entered medicine | I chose oncology because I enjoy helping patients deal with and get through one of the most difficult periods of their lives. | Community involvement | I support the Conquer Cancer Foundation. | Personal interests | I enjoy spending time with my family and watching European soccer.

    "Philosophy of care | My philosophy of care is patient-centered. I believe in a strong doctor and patient relationship that involves mutual respect, honesty, compassion and personal responsibility. I believe an essential part of ""doctoring"" is providing quality medical care in a caring atmosphere where every patient is heard and treated as a unique individual. | Why I entered medicine | Ever since I could remember I had always wanted to go into medicine. I am one of seven children. My mother was a nurse and she always encouraged me to enter the medical profession. She entered nursing school when I was 8 years old. I was brought up watching her study, listening to stories about patients and the hospital. My enthusiasm for medicine continued in high school and college; I loved the sciences. When it was time to fill out my application, I knew being a doctor would enable me to make a positive and meaningful difference in the lives of people when they need it most, and there are not many professions that give us that privilege. | Community involvement | I remain active in the community supporting my church, childrens schools and sports teams. I am also active in the American Heart Association's Lehigh Valley chapter. | Personal interests | As a mother of three beautiful children, wife of a wonderful cardiologist and a solo medical practitioner in internal medicine, personal interests are hard to fit in. My father purchased a home on the Jersey Shore in 1994, which allows me to enjoy the beach and precious time with my family. I also love to ski. I started skiing in medical school and make a yearly trek out West with my family and friends. As a physician, I am always reminding patients of the benefits of regular exercise, and I, too, try to remain physically active. In 2011, I completed the Lehigh Valley Marathon -- that was a very proud moment!". Dr. Persin is rated as an Experienced provider by MediFind in the treatment of Vitamin B12 Deficiency.

    When should I see a Vitamin B12 Deficiency doctor near Allentown, PA?

    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 Vitamin B12 Deficiency doctor near Allentown, PA?

    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 Vitamin B12 Deficiency doctors near Allentown, PA?

    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 Vitamin B12 Deficiency doctors near Allentown, PA?

    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 Vitamin B12 Deficiency doctor near Allentown, PA?

    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 Vitamin B12 Deficiency doctor search results page. 

    Why is it important to get a second opinion from a different Vitamin B12 Deficiency 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 Vitamin B12 Deficiency doctor near Allentown, PA?

    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 Vitamin B12 Deficiency 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 Vitamin B12 Deficiency 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 Vitamin B12 Deficiency doctors near Allentown, PA?

    Look for the filter feature on the left side of the Vitamin B12 Deficiency 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 Vitamin B12 Deficiency doctor that offers video calls?

    Look for the filter feature on the left-side of the Vitamin B12 Deficiency doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
