Aside from my hypothyroid symptoms disappearing, my blood work/labs being greatly improved and receiving holistic care-Dr. Stengler and his wonderful staff have provided me with top notch care and services while also providing a warm, welcoming atmosphere. I look forward to my visits-the staff is amazing and I always learn something new. I can’t thank Dr. Stengler and his staff enough.

Before coming to see Dr. Stengler I was extremely tired all the time and very irritable. I would get a migraine each month. A blood test revealed I was deficient in several areas, even though I eat healthy and take supplements. Dr. Stengler started me on bio-identical hormones and modified my supplements, and now I feel amazing! I have lots of energy, patience, and no more migraines!! It only took less than 2 months.

I was experiencing bouts of fatigue that lasted from a day or two, up to weeks at a time. I went to a number of doctors who – after doing lots of tests – told me there was nothing wrong with me. But still, I had bouts of fatigue that threatened to leave me jobless. A friend of mine told me to look for a naturopathic doctor, and I found Dr. Stengler. After telling him my symptoms, he told me I had Chronic Fatigue Syndrome. His treatments got me back to work back to normal energy levels.

An amazing office, center & staff for any type of health concerns you are facing. Dr Stengler and LaBeau have been so helpful in all aspects. Allergy testing, bloodwork, food sensitivity testing, headache issues, post covid issues, vitamins, etc. Sitting in the front office you are provided with all of Dr Stengler’s books that he wrote on natural holistic remedies, he is great at what he does! Overall the staff and doctors are so nice, helpful, accommodating and have helped me find out the root cause of any health issues i’ve had this last year. 11/10 recommend to everyone in Sandiego, worth a drive if you’re further!
