Dr. Marshall’s practice has been instrumental in my healing journey after battling breast cancer in 2023. I can’t say enough wonderful things about this practice. He is straightforward and tells you exactly what to do - he doesn’t waste your time and cares about the work he is doing. As a 36 year old woman put surgically into menopause, he has helped me manage my side effects including weight loss while also tackling ongoing gut issues I’ve had for most of my adult life. I have seen drastic improvements in my daily life including energy, mood and sleep since I started coming here in August. I highly recommend this place to anyone looking for a functional medicine doctor.

Dr Marshall, Ovie, and Devon are amazing! They are so incredibly professional and attentive. Dr Marshall is so knowledgeable and was able to help me with multiple issues, as well as my family members and nephew who suffered seizure activity on a daily basis and he is now down to very little seizure activity after his care with Dr Marshall. I have been praying for years for answers to his seizures for years, and I believe we May have finally found it thanks to this incredible team. I can’t recommend them enough.

I have been working with Dr. Marshall for the last several years. I referred many of my own clients to him as well. He has helped me recover from adrenal fatigue as well as balance my hormones during perimenopause. I truly believe in his practice, especially for women who are going through imbalances hormonally. Not only has he helped me, but also my husband recover from different leaky gut issues.
