Dr. Grethen is double board-certified and has over thirteen years of clinical experience. That background supports her work across a range of conditions, from hypothyroidism to more complex pregnancy-related care.
We recently heard from a patient who was impressed by how quickly she answers questions, effectively removing the frustration of long wait times.
She uses a direct care model, which means she doesn’t bill insurance. Instead, care is handled through straightforward, upfront pricing so she can focus more on patients and less on administrative delays.
She also keeps lab pricing transparent and often helps patients access discounted testing when possible.
While this direct model does reduce the headache of navigating insurance red tape, it may not fit every budget.
Still, patients who do use the service often point to the added time and attention as a major benefit.

So thankful for her care
We have been seeing Dr. Grethen for the last few years and are so thankful for her care. One of the biggest things we need in a doctor is someone who can see outside the scope of their specialty. Someone who looks at the entire bigger picture to ensure we aren’t missing anything which is often the case for my son. She is knowledgeable in her area of specialty but also looks at the entire picture as a whole. She is highly recommended.

2. Qasim Z. Iqbal, MD – IU Health Endocrinology – Downtown Indianapolis
Website: https://iuhealth.org/
Address: 550 N. University Blvd., Suite 2180
Contact: Phone: (317) 843-0000 | Fax: (317) 968-1006
Hours: Monday – Friday: 8:00 AM – 4:30 PM
If a complex thyroid issue has you feeling anxious, you really need a doctor who knows the latest science. Dr. Iqbal is a respected clinical educator who trains future doctors, so you know you are in good hands.
He focuses on minimally invasive procedures, including fine-needle aspiration and radiofrequency ablation, which are commonly used to diagnose and treat thyroid conditions.
Patients often mention that he’s good at explaining complicated medical information in a way that’s easy to understand. We appreciate this as it can make a stressful situation feel more manageable.
He practices across three IU Health locations and accepts a wide range of insurance plans, making access more convenient for many patients.
The main drawback is availability. Because he’s involved in teaching and research in addition to clinical work, appointments can be hard to book quickly.
Even so, many patients feel the wait is worth it for the level of expertise he provides.

3. Melissa K. Cavaghan, MD – IU Health Endocrinology – Downtown Indianapolis
Website: https://iuhealth.org/
Address: 550 N. University Blvd., Suite 2180
Contact: Phone: (317) 843-0000 | Fax: (317) 968-1006
Hours: Monday – Friday: 8:00 AM – 4:30 PM
Managing health issues during pregnancy can feel overwhelming, but the right specialist can make it much easier.
Dr. Cavaghan has over 25 years of experience focused on thyroid-related care, including complex cases during pregnancy. She also leads her hospital service line, which reflects her senior role in shaping clinical practice and care standards.
I visited her downtown clinic with a friend who appreciated how well she addressed pregnancy-related thyroid concerns.
Patients also benefit from her involvement in research and clinical trials, which keeps her work aligned with current medical developments.
Her clinic’s downtown location is convenient, with nearby pharmacies making follow-up prescriptions easy to handle.
The main challenge is scheduling. Because of her leadership responsibilities and teaching commitments, appointment times can sometimes be harder to navigate or book quickly.
Even so, her strong focus on thyroid cancer and nodules makes her a solid choice for patients who need specialized and experienced care.
4. Ascension Medical Group St. Vincent – Indianapolis Endocrinology
Website: https://healthcare.ascension.org/
Address: 8424 Naab Rd #1b
Contact: (317) 338-7490
Hours: Monday – Friday: 8:00 AM – 4:30 PM
Managing hormone imbalances often works best with a coordinated care approach. Ascension uses a large healthcare network to build treatment plans tailored to local patient needs while drawing on system-wide expertise.
They typically take time to review your full medical history before recommending a care plan.
At this campus, care goes beyond just seeing a physician. Their support system also includes nutritionists and certified diabetes educators, who can help with long-term management.
They also provide endocrine care for both children and adults in one location, making it more convenient for families.
That said, the Heather Glen Building operates on a weekday-only schedule, which can make visits difficult for people with full-time jobs.
Still, having emergency services on the same campus adds convenience and reassurance when urgent issues come up.
5. Diabetes and Endocrinology Specialists: Sundaram, Vidya, MD
Website: https://www.franciscanhealth.org/
Address: 5230 E Stop 11 Rd #150
Contact: (317) 865-5904
Hours: Monday – Friday: 8:00 AM – 5:00 PM
Finding a doctor who can handle both diagnosis and procedures can save a lot of time. Dr. Sundaram specializes in thyroid nodules and performs biopsies directly in her clinic, helping streamline care without requiring multiple referrals.
She is double board-certified in internal medicine and endocrinology, giving her a broad understanding of both thyroid conditions and overall health.
She also speaks Hindi and Tamil, which can make it easier for patients in the community to communicate clearly and feel more comfortable during visits.
Being part of the Franciscan Health network also helps keep care coordinated across different providers if additional treatment is needed.
However, she works on a Monday through Friday schedule. This can be less convenient for people with standard work hours.
Luckily, she is currently accepting new patients, which can make access easier compared to many specialists.
Customer Reviews:
