in Calabasas, CA |
This is the kind of doctor you want to see. Someone who really cares about patients and knows what he is doing. Highly appreciated and very well recommended!!
Simi Valley, CA |
Dr Bjelica is the best of the best! He's the kindest, most knowledgeable endo I've encountered. Great sense of humor too. He's taken great care of me. When I was at my OB/Gyn talking about getting pregnant, the OB asked me who I'm seeing for my thyroid. When I said Dr. Bjelica he said, "Good. Then I know you're in good hands". This OB is the top in his field and helps with fertility. They know their stuff. Dr. B is A+

Dr. Bjelica has a special talent for highest quality FNA biopsy for thyroid tumor. If you have a thyoid nodule, I highly recommend you have Dr. Bjelica do the biopsy. He found the tumor that others missed in my 3 cm nodule. He explains everything and is very personable. His office team is terrific. He is an outstanding practitioner who you can trust to take excellent care of you.

in Agoura Hills, CA |
Thank goodness I found Dr.Bjelica. He performed my ultrasounds, biopsies and exams all in one room at one time. I didn't have to go to several different places like many clinics require. Each appointment I was in and out within one hour. Dr. Bjelica is honest, straightforward, funny, charming, thorough and punctual. His office is clean, well decorated, the staff are courteous, efficient and knowledgeable. Dr. Bjelica even ordered my prescription for after surgery, and told me what to expect.

I was beyond impressed with my experience at this doctor's office.He was really knowledgeable and made me feel comfortable throughout the appointment. I was consulted many MDs in my life and it's rare I've found one as knowledgeable, accommodating and caring as Dr. Bjelica. 6 stars if I had them!
