Doctor/Treatment Recommendation for Diabetes and Hypertension Patient in Chandigarh or Mohali

Anybody has luck with finding a nice doctor or a treatment that had really worked with their Diabetes and Hypertension condition ? I'm asking for my mother who is 53 y/o. Her Fasting Sugar levels wont come down below 170, and B/P of 140/100. She's currently taking Metformin 500mg twice a day and Amlodipine for Hypertension but is a band-aid approach rather than the root cause one. Any recommendations would be helpful!
