About Me

Hi, I'm Sammi 🤍

I'm a mom of two (hi Remi and Cole!), married to my high school sweetheart Zach, and a Long Island girl through and through. Born and raised in Merrick, now raising my family in Huntington.

I spent years teaching K-5 STEM. Then I became a mom, started pumping, and the only advice my OB gave me was to follow someone on Instagram. So I got certified instead. Now I'm a Certified Breastfeeding Counselor and pumping specialist, and I've helped 100+ moms find a plan that actually works for their life.

I'm also a real estate agent with Signature Premier Properties, a 3x children's book author, and co-host of the Struggle Out Loud podcast. Mama of all trades, for real.

You're not doing it wrong. And you don't have to do it alone.

xo, Sammi

What People Say

Real Estate Reviews

★★★★★

"Sam is AMAZING! The home buying process is stressful already, and Sam made sure that we were not only comfortable, but happy the entire process. She kept close contact with us and all parties involved, and reached out often to check in. I cannot recommend Sam enough to be your realtor!!!"

Annette Tekverk · bought in Smithtown, NY
★★★★★

"Samantha was incredible! She helped us navigate a near impossible situation multiple times. She was always optimistic when we were not. And she helped us get our dream home in the end. Forever thankful!"

Micheline Goulart · bought in Northport, NY
★★★★★

"Sammi is not only a great friend, but the best realtor experience I've ever had. She builds relationships with everyone involved and single handedly got our deal to go through by working closely with the agent, lawyers and all hands involved."

What Moms Say

Lactation & Pumping Reviews

★★★★★

"I can't say enough amazing things about my experience with Sammi as my lactation consultant. Because of her, I am successfully breastfeeding and producing, something I honestly wasn't sure would be possible. She didn't just offer encouragement — she equipped me with real knowledge and confidence."

Jillian Laviano
★★★★★

"Sammi completely changed my pumping experience. I was on the verge of quitting, just 2 weeks in, and with simple yet effective tools and knowledge I am now 12 weeks in with a healthy supply. I highly recommend Sammi for anyone exploring a breastfeeding/pumping journey."

Samara Pomerantz
★★★★★

"I honestly wasn't planning on breastfeeding, so I started with very little knowledge. Sammi was incredible from the very beginning — she checked in on me constantly, almost every day. I truly don't know what I would have done without her help during those early postpartum days."

Holly Roselle · 9 reviews, 5.0 overall
★★★★★

"I worked with Sammi before I had my son, and I'm so grateful I did. She explained everything clearly and shared so much more helpful information than the lactation coach I met at the hospital. I felt truly prepared because of her guidance."
