SAN FRANCISCO, CA, September 15, 2026 /24-7PressRelease/ — Spring Fertility is proud to announce that six of its physicians have been recognized as Castle Connolly Top Doctors. Only 7 percent of the nation’s licensed physicians are chosen each year as Castle Connolly Top Doctors for their specialties in their regions.

The physicians recognized include:

Temeka K. Zore, MD – California
Sacha A. Krieg, MD/PhD – Oregon
Paula Amato, MD – Oregon
Peter C. Klatsky, MD – New York

The recognition is particularly meaningful as Spring Fertility continues its expansion across the country, including the recent opening of its Long Island clinic in Garden City. Led by Dr. Peter Klatsky and Dr. Chantae Sullivan-Pyke, the Long Island practice brings Spring Fertility’s signature model of personalized, physician-led fertility care to more patients throughout the New York metropolitan area.

“It’s an incredible honor to be recognized as a Castle Connolly Top Doctor,” said Dr. Chantae Sullivan-Pyke, Fertility Specialist at Spring Fertility. “I’m proud to be recognized alongside such an exceptional group of colleagues whose dedication to clinical excellence and compassionate care inspires me every day. What makes Spring Fertility truly special is our shared commitment to combining world-class expertise with innovation and personalized care so every patient feels supported, informed, and empowered throughout their fertility journey.”

Further demonstrating its commitment to innovation, Spring Fertility recently launched its Personalized IVF Outcome Calculator—a first-of-its-kind tool designed to provide patients with individualized IVF outcome estimates based on their unique clinical characteristics. By translating complex clinical data into personalized insights, the calculator helps patients better understand their potential path to success and supports more informed conversations with their physician.

The Personalized IVF Outcome Calculator reflects Spring’s commitment to combining scientific rigor, advanced technology, and transparent, patient-driven care. Together with a nationally recognized team of physicians, the tool represents Spring’s continued investment in delivering a fertility experience that is both deeply personalized and grounded in evidence-based medicine.
