Dr. Glenda Callender is number one in my care. I'm in good hands with a doctor that takes time to explain in very very good detail about what this parathyroid is and how she is going to operate on me. I trust her with how many times. She has helped so many people with this problem!!

Dr. Callender is not only an incredible surgeon, she is a wonderful person as well. She has a gift of making people feel so comfortable and confident that they are in the best hands. I certainly felt that way and can't say enough great words about her.

Dr Callender was a true professional. She was very reassuring in her evaluation of my situation. The results were proven to be what she had diagnosed. I would not hesitate to, literally, put my life in her hands again. Thank you doctor.

What began as a scary experience to have to undergo turned into a very pleasant one with Dr Callender. I found her to be very knowledgeable, thorough, clear, concise, confident, and kind. I would highly recommend her to be your surgeon. The complete office staff was on top of their game too which is so hard to find lately.

Upon being diagnosed with Hyperparathyroidism I was referred to Dr. Callender through physicians and friends. Surgery is the best treatment as I learned for this condition. I could not have received better care than I did from Dr. Callender who met my anxiety and trepidation with knowledge and compassion at every step of the way including holding my hand as I underwent the anesthesia for surgery...something I needed.
