Patient's Reviews

Thomas W Schaaf Sr. Founder & CEO of XpeedStudio

Dear Dr. Masood,
A turning point in my life was hearing the words, “I think this has been a miss - diagnosis”, and I am thanks to you, now back on the road to health and happiness. I trust you will find this chronicle of the development of modern medicine, right in our neighborhood, interesting and a confirmation of your choice of a life giving career.
With admiration and respect

Nina M Bestall Founder & CEO of XpeedStudio

I was referred to Dr. Masood by a friend and we both love and trust Dr. Masood for our health care. She is very caring and spends as much time with you as you need. I'm also impressed with how much she remembers about my past visits without checking the computer! She has been very helpful in prescribing the right medicines for me and advising me on treatments.

Elaine Murray Founder & CEO of XpeedStudio

I absolutely love Dr. Masood. I have been a patient of hers for years and find her to be so very caring and giving of her time to explain things thoroughly. I have absolute faith in her and her diagnosis has always been correct

Mary T. Abraham Founder & CEO of XpeedStudio

Dr. Masood, You held me up when I thought I couldn’t, I saw your positivity and grace and I then… could. Thank you for being honest, caring, strong and unrelenting in care of my mother. You are amazing.
