Which of these are you?

We Understand

Something
Feels Wrong

You've done the right things. Yet your body isn't responding the way it should.

01

You feel exhausted despite doing everything "right"

02

Your body doesn't recover the way it used to

03

Pain limits your movement, confidence, or performance

04

Brain fog, weight gain, or inflammation feels unexplained

05

You're aging faster than you want, and no one is connecting the dots

These Aren't Things You Should Ignore.

They're Signals Worth Understanding.

The Aether Method™

Understand. Restore. Optimize.

Most healthcare manages symptoms. We look for why they started. Fatigue, brain fog, weight that will not move, hormone changes, poor sleep, joint pain: we test the biology behind each one, treat what we find, and help you keep the gains for the long run.

LAYER ONE: UNDERSTAND

Testing That Explains Your Symptoms

Before we treat, we listen. Before we prescribe, we test. Many patients come to us with labs that read "normal" while they feel anything but. We start with your story: how you sleep, your energy, your weight, your mood, how you recover. Then we run the panels that explain it, including hormones, thyroid, insulin and blood sugar, and inflammation markers, and build a plan around what we find.

01Advanced blood panels: the numbers behind fatigue, weight, and mood
02Biological age testing: how fast your body is actually aging
03VO₂ max & metabolic testing (PNOĒ): fitness and how you burn fuel
04Inflammation & oxidative stress markers: for joint pain and slow recovery
05Full hormone panel: testosterone, estrogen, progesterone, thyroid, cortisol
06Microbiome analysis: gut health and digestion
07Genetic profiling alongside your sleep, diet, and training data
01Therapeutic Plasma Exchange (TPE): for chronic inflammation, long COVID, and autoimmune symptoms
02Hormone replacement (pellet & non-pellet): testosterone, estrogen, progesterone, thyroid
03Peptide therapy: recovery, injury repair, sleep, and gut healing
04Ozone therapy & Major Autohemotherapy (MAH): immune support and joint pain
05PRP, exosomes & stem cells: joint, tendon, and ligament injuries
06Targeted medications, including GLP-1 for weight and blood sugar
07Pharmaceutical grade supplements for nutrient gaps we find on testing

LAYER TWO: RESTORE

Treatments Matched to the Cause

Once we know what is driving your symptoms, we treat it directly. That may mean hormone replacement for low testosterone or menopause symptoms, GLP-1 and metabolic care for insulin resistance and stubborn weight, PRP or peptides for joint pain, or plasma exchange for chronic inflammation. Each plan is built for you and supervised by Dr. Christian.

LAYER THREE: OPTIMIZE

Lifestyle Medicine: Sleep, Food, Movement, Stress

Treatment opens the door. Sleep, stress, food, and movement decide whether the gains last. We build these into your plan alongside treatment, so the work you put in has a foundation that holds up over years, not weeks.

01Sleep: falling asleep, staying asleep, waking rested
02Stress & nervous system regulation: irritability, burnout, poor recovery
03Exercise prescription & recovery: training that fits your labs and your joints
04Nutrition & metabolic flexibility: blood sugar, cravings, and weight
05Behavior change: habits that stick without white-knuckling
06Community, purpose & faith: the parts of health a lab cannot measure

A Systems-Based Approach To Longevity

While every patient is unique, we consistently find that health, performance, and longevity are shaped by a handful of interconnected biological systems. These systems form the foundation of how you feel, function, and age.

The Foundations of Healthspan

Health is never just one system.

Cellular Health

Restore the biology that drives energy, recovery, and resilience.

  • Mitochondrial performance and cellular energy output
  • Oxidative stress markers and inflammation drivers
  • Regeneration capacity and tissue repair readiness
  • Precision therapeutics tailored to your biomarkers

Metabolic Resilience

Stabilize the systems that regulate weight, fuel, and longevity.

  • Insulin sensitivity and glucose regulation mapping
  • Lipid optimization and cardiovascular risk refinement
  • Body composition and metabolic flexibility improvements
  • Hormone balance aligned with your physiology

Inflammation & Immune Health

Restore balance to the systems that regulate healing, recovery, resilience, and healthy aging.

  • Root-cause screening for chronic inflammatory triggers
  • Immune modulation with clinically guided protocols
  • Recovery optimization for joints, soft tissue, and mobility
  • Long-term stability through diagnostics and lifestyle integration

Hormonal Optimization

Restore biological rhythm, vitality, and performance longevity.

  • Precision hormone diagnostics and interpretation
  • Personalized optimization protocols
  • Energy, cognition, sleep and recovery regulation
  • Long-term endocrine resilience planning

Performance, Longevity & Resilience

Build the capacity to perform, adapt, and thrive throughout every stage of life.

  • Biological age and longevity optimization strategies
  • Physical performance, strength, and functional capacity
  • Cognitive resilience and peak mental performance
  • Recovery capacity and physiological adaptability
  • Long-term vitality and healthspan planning

YOUR HEALTH. YOUR GOALS. YOUR PROGRAM.

Physician-Led Programs
Built Around You

Every program starts with the problem you walk in with, tests the biology behind it, and treats the cause. Built around your results, goals, and stage of life.

Where most people start

Hormones and metabolism are one system. We treat them that way.

Low energy, stalled body composition, poor sleep and a flat mood usually have a measurable cause, and it is rarely one hormone in isolation. We test both systems together and read the results against each other.

Hormone optimization

When the labs are “normal” and you still feel flat.

Testosterone, estrogen and progesterone, thyroid with the free hormones, and the HPA axis, read against how you actually feel and what you are asking your body to do. Where treatment is right, it is bioidentical, supervised, and re-tested rather than set and forgotten.

  • Full hormone panel, not a single number
  • Bioidentical therapy where it is warranted
  • Re-tested, then adjusted
Hormone optimization Written for hormone patients: is this you?

Metabolic health

The scale is the last thing to move, and the least useful.

Fasting insulin, HbA1c, lipids and body composition tell you what is driving weight and energy long before the scale does. Where a GLP-1 medication is part of the plan it is prescribed and monitored by a physician, alongside the muscle and nutrition work that decides whether the result holds.

  • Insulin and body composition, not just weight
  • GLP-1 prescribed and monitored by a physician
  • Built to hold after the medication
Metabolic health

Telehealth Available

You do not have to live near Philadelphia to be our patient.

Hormone and metabolic care is mostly conversation, laboratory work and adjustment over time. All three travel well. Patients across Pennsylvania do this with us on video, with their blood drawn close to home.

Where this is available. Dr. Christian is licensed in Pennsylvania, so telehealth is available to patients who are in Pennsylvania at the time of the visit. If you are elsewhere, the office in the Philadelphia area sees patients in person.

Start with hormones Ask about a video visit
  1. Step 1

    A consult on video

    Your history, your symptoms and what you want to change, with the physician rather than an intake form.

  2. Step 2

    Labs drawn near you

    We send the order to a draw site close to home. You do not travel for a blood test.

  3. Step 3

    Results read together

    We go through the panel on screen, and you leave with the plan written down rather than a portal message.

  4. Step 4

    Follow-up on video

    Re-testing and adjustments happen on the same schedule they would in the office.

Innovative, attentive, and effective. Dr Christian knows how to look at the big picture. He is compassionate and understanding and focused on helping you achieve your goals. You never feel rushed and always feel heard. He is truly one of a kind and I would highly recommend him.
Dr. Christian is a friend and former colleague that I would trust with my life and those of my family. His professional skill and ethic in the field of physical medicine and rehab is truly special. His dedication to improving access to healing is one to be honored!
Dr Christian and his practice are hands down one of the best. His holistic approach to medicine is something you rarely see in healthcare. As a Physical Therapist, I often refer patients to physicians to collaborate and my number one answer is Dr. Christian at Aether Medicine. The time, care, and determination he shows to his patients is uncanny. Recommend 10/10.
Dr Christian has been my doctor for several years now. I was unable to walk when I first met him. 5 years later I am able to walk and I am again a functioning beyond anything I would have dreamt would be possible. I am walking again and also driving. I'm able to live my life again. Please allow Dr. Christian help you should you need his guidance.
Dr Asare Christian is taking care of my great aunt Inez who will be turning 102 years old this year. He has been very caring and compassionate. She has shown improvement since the treatment and continues to assist with her ADL's and gentle exercises. I would highly recommend Dr Christian to anyone who is experiencing pain.
Dr Christian is FANTASTIC! Very knowledgeable and works very well with his patients on trying to create well rounded approach to their health and wellness. Highly recommend him to anyone looking for help!
If you are looking for someone to truly listen to you as a patient, you need to schedule a visit with Dr. Christian. He does not simply type symptoms into his laptop and wait for the program to instruct how to treat your illness. He understands you are an individual, and considers all aspects of your health. He treats you as a whole person, not a list of symptoms. If you have been frustrated by the health care system, and have yet to find relief for your pain, I highly recommend Dr. Christian and Aether medicine.
My wife experienced a concussion in a car accident a few years back and was treated by Dr. Christian. She could not move her neck left or right for a month along with terrible pain and headaches, which led to vision problems. From her first visit, Dr. Christian helped her get her neck moving side to side again. From that point until now, she feels that after going through all that, she has a normal life today thanks to his treatment. He truly cares about the patients, they are not just numbers or statistics to him. She is totally grateful to him for getting the pain under control and now at his new practice, the peptide therapy has helped her get her Polycystic Ovary Syndrome under control. This helps her with weight loss (down 58 pounds), and the PCOS symptoms have almost disappeared. She is grateful to have an amazing physician like him in her life, we are both very thankful for everything he has done for us!
Dr Christian is a fantastic pain management doctor. He looks at you holistically and is very compassionate and understanding. He listens to you and works with you to come up with the best treatment plan for you. Even if it requires referring you to another doctor. I have had 3 spine surgeries with constant epidurals and rhizotomies in between them. My last surgery was 3.5 years ago and afterwards Dr Christian came up with a new plan for my muscle spasms. It has been a life saver for me, as my falls had been less frequent for me and I haven't needed any additional therapy besides what I do at home. Plus the best part is, I do not want to be on narcotics yet and he respects that and treats me without ever needing to use a narcotic! He truly listens to you and works with you, to care for you! I wish there were more doctors like him!
Extraordinary. Brilliant. Innovative. Compassionate. He changed my life! Chronic cervical pain brought me to Dr. Asare B. Christian. For years doctors/surgeons restricted my movement and wrote pain prescriptions. I challenged Dr. Christian to help me eliminate the prescriptions (morphine), build the physical/mental strength to minimize the pain and live an active life. He became my partner on an amazing journey. We put together a plan for my recovery. He educated and encouraged me. He listened to my personal goals and got to know my family. He provided the latest practices and resources so I could accomplish what all the other doctors said was impossible. Dr. Christian's staff at Good Shephard are smart, dedicated, efficient, customer-centric professionals who treat each patient with warmth and kindness. I walk five miles every day. I dance, exercise, garden, do all the things I was told I should never do. He is, quite simply, remarkable.
Dr. Christian is hands down the best in the business. Not only in medicine, but healthcare. True reformative and proactive healthcare. His approach is integral, conscience, and thorough. He treats people like a human being and looks at ALL aspects of who you are to better understand how he can work WITH you to provide best outcomes. It's never just about the pain. It's about the body and how the mind perceives the pain. He equips all his clients with the tools to become your best self beyond the pain. If the pain is what brings you to Dr. Christian then consider yourself blessed. If you work with him and truly follow and use the tools and strategies he equips you with, prepare to be amazed that your quality of simply BEING renews itself and that you may even rise to new heights you never thought possible before you ever had the pain. It's possible. I promise. From one former chronic pain sufferer to another, not only is there hope with Dr. Christian on your team but a whole new world of wellness and possibilities.
Dr. Christian was very kind and thoughtful. His exam was thorough. He listened to my concerns and offered modalities to improve my condition that make good sense.
Dr. Christian is a very knowledgeable, compassionate and caring physician. He was very present when he met with my wife and me. You feel that he really cares and wants to help you heal. Highly recommended.
