Habitat Optimizing Plasma Exchange
MaxWell Clinic's patented H.O.P.E. therapy removes harmful proteins and optimizes blood composition to support cellular regeneration. This advanced treatment targets neurodegenerative conditions, autoimmune disorders, and aging-related decline by creating a healthier internal environment for natural healing processes. Patients receive personalized protocols combining plasma exchange with targeted supplements and growth factors.
Ketamine Infusion Therapy
Our ketamine therapy offers rapid relief for treatment-resistant depression, anxiety, and PTSD through intravenous administration. Combined with integration coaching, this evidence-based treatment creates new neural pathways while addressing underlying emotional trauma in a controlled clinical setting with continuous monitoring.
MaxWell Care Program
This 3-12 month program provides comprehensive functional medicine care with a dedicated healthcare team. Patients receive advanced diagnostics, customized treatment plans, and ongoing support through regular clinician visits, nutrition counseling, and cellular health assessments for chronic condition management.
Neurofeedback Therapy
Our neurofeedback system measures brainwave activity to train optimal neural patterns for improved cognitive function. This non-invasive treatment addresses neurological conditions by reinforcing healthy brain activity patterns through real-time feedback mechanisms in a clinical setting.
IV Nutrient Therapy
Custom IV formulations deliver high-dose vitamins, minerals, and antioxidants directly into the bloodstream for maximum absorption. This therapy supports immune function, energy production, and cellular repair through personalized nutrient protocols administered by experienced infusion specialists.

The doctors at Maxwell Clinic are great. However, the new Maxwell Care plan is not something many people can afford. Riverside Village Clinic in East Nashville has a similar blend of functional and Western medicine for an affordable price. Also, they take insurance. And they are incredibly kind. So if you lost your wonderful Maxwell doctor when they switched to the new plan, you could check out Riverside! Hope this helps others who lost their doctors!

I've been fighting digestive issues, adrenal glad depletion, and thyroid and hormonal imbalances for years. It wasn't until I was directed by my functional doctor to see Emily Spring at Maxwell Clinic that I realized there was hope for me yet to heal and become my strong, healthy self again. You feel cared for and encouraged, and everything is explained to you as to why they recommend certain tests and how those tests pertain to you.
Most of all (and the biggest reason I went in the first place), they search diligently to figure out what the root cause of your ailments is to heal you truly from the inside out. They strive to work WITH your body, and not against it, and do it as naturally as possible. If you want to regain your health, joy, and peace. I recommend you give Maxwell Clinic a visit. You owe it to yourself!

I have had the ongoing privilege of not only being cared for by the health care providers at the MaxWell Clinic but also of being a part of the MaxWell Clinic team and family for the past two years. What is so unique about this practice is the way in which each patient obtains individualized treatment recommendations that target true healing and long term wellness. As no person is the exact same, no journey to sustainable health is exactly the same either.
After being a patient as well as working in a multitude of healthcare settings and facilities across the country, I can honestly say that I have never experienced healthcare providers who are as knowledgeable and care as deeply for their patients as they do at the MaxWell Clinic. This place is truly one of a kind!

So grateful to have found this practice. Emily Spring has such a collaborative spirit yet is equally resourceful. The office is always clean and tidy and everyone I've encountered is very helpful. I would highly recommend this practice for those looking to partner with their practitioner as they seek wellness in all aspects of their lives.

Nashville and I are both SO LUCKY to have Dr David Haase and the Maxwell Clinic. If you are someone who has come to accept that not feeling well is your "normal", I highly recommend taking the time to apply to be a patient here. Dr Haase and Emily Spring will give you the information and range of testing necessary to improve your health systemically, instead of slapping medications onto conditions as a bandaid.
I was able to balance my hormones after 12 years on birth control and 4 years severely underweight, because of my work with Dr Haase at the Maxwell Clinic. The staff and nurses are all incredibly professional and proficient as well!

Emily Spring, PA, has taken such good care of me. I'm healthy by traditional medical standards, so I've not felt heard by most physicians. However, Emily took all my concerns to heart, ordered the necessary tests, and came up with a doable plan. My insurance does not cover much for the office visits, tests, or supplements - so it's expensive - but I am willing to invest money into this collaborative blueprint for my short- and long-term health.
In the two visits, I've already seen improvements in health issues I've been unsuccessfully trying to overcome for more than a decade. I am grateful for the Maxwell Clinic and would highly recommend it to all!

MaxWell has helped me completely transform my health- mind, body, and soul. I was able to find a diet that was suited specifically to my body, supplements that helped me in the places I was lacking, and gave me a team of people that I know I can rely on to keep me on a healthy course of wellbeing. They've helped both of my parents solve multiple health problems and lose weight, and I would recommend MaxWell to any person who would like help becoming a healthier person.
