You Deserve To Feel Better

Our healthcare systems are overloaded and it’s getting harder to get help.

(I know this firsthand - I’m a doctor.)

As a working MD with 18 years of experience, I know that health professionals wish they could spend more time with patients, to guide, to advise and above all, to listen - but they just can’t.

Now I think I have a solution.

Hi! I’m Mariana Calleja MD

  • A medically trained healthcare professional with 18 years of experience in Chronic Pain, Palliative Care, and Occupational Medicine.

  • I hold a Master’s degree in Chronic Pain Management.

  • I’ve seen both ends of the healthcare spectrum—from preventive care to chronic disease and end of life stages—which led me to focus on helping people improve their lifestyle and long-term health.

  • I'm a strong advocate of integrative and functional medicine, mental health, and burnout prevention.

  • I believe we are in a new Medicine era where we lead with heart, humanity, and connection.

Our healthcare systems are stretched to their limits - and that means you can’t always get the help you need and deserve.

The numbers are clear…

  1. The healthcare workforce is in crisis.

    “WHO estimates a projected shortfall of 11 million health workers by 2030, mostly in low- and lower-middle income countries.” Source

  2. Patients are already suffering the consequences.

    According to 42% of 23,507 respondents (16-74 y/o) from 34 countries surveyed July-August 2022 by Ipsos Global Health Monitor, shortage of staff is shortage of staff as one of the biggest problems facing the health system in their country, making it the number 1 issue internationally along with access to treatment and long waiting times.” Source

  3. Rising healthcare costs are straining budgets worldwide.

    “The Economist Intelligence Unit predicts global healthcare expenditure will grow by 6% in 2025, outpacing inflation.” Source

You need a medical professional who has the time, knowledge, and empathy to help you understand your health.

What you need

is someone with the time to listen

My two roles as your medical advocate are:

  1. Provide clear advice and reassurance when you can’t immediately get a doctor’s appointment—helping you avoid unnecessary visits and addressing concerns efficiently in a single session.

  2. Guide you step by step so that when you see your doctor, you have all the information you need, know the right questions to ask, and make the most of every minute with them.

I cannot change the system, but I can help patients deal with the system.

Here’s How I Can Help You:

  • I explain your medical information in clear, simple terms for you to understand.

  • We go over your test results together so you know exactly what they mean

  • I guide you on the next steps in your care so you feel confident moving forward.

  • I help you stay healthy with personalised prevention and wellness advice.

  • I guide you on how to better communicate with your treating physicians, so you get the most out of every appointment.

  • I make the healthcare system easier to navigate, so you get the right care without unnecessary stress.

  • I’m here to answer your questions and support you throughout your healthcare journey

In Essence:

I help you understand your health, make informed decisions, communicate effectively with your doctors, and navigate the healthcare system with confidence.

"Wherever the art of Medicine is loved,
there is also a love of Humanity."

— Hippocrates

What People Are Saying

  • "The first step of mystery and uncertainty disappears as soon as you connect with Dr. Mariana, turning into a sense of interest to connect with the cause of the problem, not just alleviate a symptom. All of her advice continues to have an effect on me. Not only did she help solve my discomfort, but also allow me to establish habits that are still helping me.”

    Jaume Marin, Spain

  • “Dr. Mariana is a kind and caring doctor. She explains how the body works in a straightforward, clear manner, but in a way that is easy for the layperson to grasp. Perhaps the most appealing part of her approach is that she focuses on teaching people how to prevent problems, rather than ignoring risks that can lead to physical or mental health issues. I highly recommend her.”

    Louise Haynes, Japan

  • "I greatly appreciate conversations with Dr. Mariana as I have always found her to be exceptionally empathetic, with enormous consideration for her clients and most importantly her advice is reliable. Her professionalism and integrity in my experience has been beyond question."

    Terry Lee, UK

  • “I have known Dr. Mariana for over 20 years, and I can say she is an exceptional professional. What sets her apart is not only her medical knowledge, but the heart with which she accompanies each person. She has an integral, human, and compassionate vision of health, always seeking the root of the problem and offering sustainable solutions to improve quality of life. Her work reflects what medicine can and should be: an act of love.”
