Kids have a funny way of telling their birth stories.

Mandie recently shared her experience delivering Lincoln with the AFA OB/GYN team:

"I found AFA after moving to central Mass because I liked that the practice had midwives and a forward approach to women's health. I saw most of the midwives when I was pregnant, but was under the care mainly of Avery and Sherri, with Dr. Strehle as my OBGYN.

I was injured while pregnant, which complicated my mobility and caused me significant pain. My water broke naturally the day before my due date. After about 12 hours in labor, my progress was stalling completely. The nurses adjusted my position and Sherri came to check on me again. She called for a c-section, and Dr. Strehle delivered Lincoln at 2:01 in the morning on his due date.

Lincoln likes to tell people, “She (Dr. Strehle) cut me out of mama with a big knife and that's how she got me!”

When we talked to Sherri the next day, she said she felt something wasn’t right and it was time to call it to keep us both safe. When we saw Dr. Strehle afterward, she skipped around with Lincoln and told him he looked like me.

I am very thankful for the wonderful care I received and for my healthy beautiful boy."

Massachusetts is consistently ranked among the best states in the country for maternity care.

Hospitals across the state regularly lead national rankings — including Emerson Hospital’s Birthing Center just outside Boston, which has been named one of America’s Best Maternity Hospitals by Newsweek and recognized by U.S. News & World Report for Maternity Care.

Emerson also provides advanced newborn support through its Level II Special Care Nursery, offering specialized monitoring and care for babies who need extra attention after birth, supported by neonatology specialists affiliated with Massachusetts General Hospital.

At AFA OB/GYN, our patients receive the personalized care of a private, women-led practice while delivering at a nationally recognized maternity hospital.

And the team delivering that care? Our providers have been recognized as Boston Top Doctors. Because exceptional care isn't something we aim for. It's the standard we're held to.

Private practice care, where your provider already knows your name. Nationally recognized maternity care, right here in our community.

1 in 10 women has endometriosis.
The average diagnosis takes 10 years.

Ten years of being told “this is normal.”

It isn’t.

If you’ve ever been dismissed, minimized, or sent home without answers, this post is for you.

Pelvic pain.
Heavy periods.
Cycles that are completely unpredictable.

These are some of the most common things patients come to us for, and also some of the most commonly dismissed symptoms in women’s health.

If you’ve ever been told:
“That’s just how periods are” or “It’s probably just stress,” please know this:

Painful periods are not normal. Heavy bleeding is not something you just live with. Irregular cycles are your body asking for attention.

Some conditions these symptoms can signal:

• Endometriosis: affects 1 in 10 women. Diagnosis takes an average of 10 years and can impact fertility, mental health, and quality of life.

• Uterine fibroids: affect 70–80% of women by age 50 and can cause heavy bleeding and pelvic pressure.

• PCOS: affects 1 in 8 women and impacts hormones, metabolism, skin, mood, and fertility.

• Perimenopause: can begin in your late 30s, affecting sleep, mood, libido, bone density, and heart health.

• Abnormal uterine bleeding: one of the most common reasons women see an OB-GYN and always worth investigating.

You don’t have to figure this out alone.
You don’t have to minimize what you’re feeling to seem “less dramatic.” And you don’t have to wait until your annual visit to talk about it.

AFA OBGYN is currently accepting new patients.

A high-risk IVF pregnancy during an already uncertain time, and she felt safe the whole way through.

Molly trusted Dr. Sienkiewicz and the AFA team with one of the most important moments of her life. What could have been an incredibly stressful journey became one defined by unwavering support.

Who better to guide a woman through moments like these than another woman herself?

AFA is proud to be an all-women practice dedicated to caring for our patients like Molly. Thank you Molly for trusting Dr. Sienkiewicz and the entire AFA family. 💙

Happy National Doctors' Day 💙

Your doctor has seen you at your most vulnerable. Held your hand through the scary moments. Celebrated the best ones with you.
And then went home and did it all over again tomorrow.

Behind every healthy pregnancy. Every answered question at midnight. Every hand held in the OR, there's a doctor who chose this. On purpose. Every single day.

Today we celebrate the women who built this practice, grew this practice, and show up for every woman who walks through our doors.

Dr. Emily Strehle, Dr. Dorothea Letner, Dr. Erin Sienkiewicz, thank you for showing up for our patients. 🫶

Dr. Laura Silk, we are holding you close while you're away. 💙

Dr. Ingrid Balcomb, thank you for founding a practice built on compassion and care for women. Your legacy lives in every patient we serve. 🩺

We are because they were.

If you'd like to schedule a consultation for your daughter or learn more about our adolescent care services, give our office a call. We're committed to making every visit a positive, empowering experience.
