My life and well-being have changed since I began coming to the Gain Wellness Center. I was feeling like all hope was lost. No one was listening to me at my own personal doctor’s office. The answer to every issue was “ more medication”. Since meeting Dr Walia, My blood pressure has never been lower. My energy level hasn’t been this great since my twenties and I’m 62! I sleep better. My anxiety has disappeared. I have never felt better or more cared for since I met Dr. Walia Mandeep. I am forever grateful.

Dr.Walia was such a tremendous help with her mentorship & nutritional guidance that I have seen such a dramatic change in my health. I’m currently down 20 pounds; I feel more energetic & my sleep has improved tremendously. I still have a ways to go weight wise but I’m thrilled that my glucose is down 7 points and A1C is down also. She has a wonderful staff & I will continue to follow her advise to continue on my health journey.

It was my best decision to enroll and get healthy under the care of Doctor Wahlia. The four months program went by quick and smooth. At first I was not fully convinced that I will get better. Dr Wahlia proved me wrong. She knows exactly what my problem is. She had asked me to stop all my current medications. With her close guidance, supplements, healthy diet I now feel better with my abdominal issues(i. e. pain, bowel movements, heart burns etc). I’m happy and glad that I have met Dr. Wahlia and Alisa. I recommend Gain Wellness Center to anyone who needs help. Thank you
