I can honestly say that Dr. Lee has truly made a difference in my mobility and flexibility. Any concerns I have ever had were always addressed and I leave his office feeling refreshed and mobile. I play a lot of sports and get banged up time to time as to why I need to see him time to time. I highly recommend his expertise and services. He truly cares in the process of healing you and to get you back up and running in no time. Thanks Dr. Lee!

Dr. Derek Lee has been a vital part of my integrative wellness regimen. I have been a patient for 25+ years and I highly recommend his care for anyone looking to improve mobility, maintain good posture, and eliminate pain and inflammation in the body. Recently I have also seen Dr. Lee for a flare up of digestive issues and I cannot say enough praise about the improvements I have seen from the first treatment targeting the symptoms with acupuncture. I have also had the opportunity to receive acupuncture for fine lines on my face and love the results. I saw improvements in a scar on my face that I had acquired in 2020 (so it wasn't new) and I would say the scar is 80% less prominent and my skin looks and feels smoother. I really find the time I have for my sessions also gives me time to fully rest and calm my mind and this has also been vital in helping me maintain a healthier outlook on life. The integrative approach Dr. Derek Lee provides gives me peace of mind and I recommend being under his care to anyone for acute or chronic issues.

My husband introduced me to Dr Lee. For years I’ve had stomach pain every time I put something in my mouth including water. I had recently had colonoscopies, endoscopies over the years and they have never been able to give a reason why I had to suffer with this. I was given various acid reflux meds in hopes of solving the problem. After 11 years I figure one more attempt at solving the problem. After one week of the TH 1 and Deep Immune Activator I was pain free from eating. An added by product I noticed is this. I have 5 grand children. When they visit at least one of them has some kind of cold. As a Doula I deal with the most vulnerable (brand new babies). I’m always cautious and protective of my clients. To ensure that I don’t pass on any illness to them or baby. But my granddaughter was visiting and her mom did not tell me that she was sick. I was sooooo upset. Thank goodness I did not have any client delivering at the time. But let me tell you my husband got sick, my son got sick. But not ME. It was empowering to know that I was fighting against viruses. I am thankful for listening to my husband. Just this one time. I’ll give him a win
