Idelsis Trelles


Idelsis Trelles, PA-C, was born in Miami and didn’t stray far from her roots when she joined the team at South Miami OB/GYN Associates in South Miami, Florida, in 2007. Idelsis completed her undergraduate degree at Florida International University and received a Bachelor of Science degree in chemistry. She then completed her studies at the Miami Dade College Physician Assistant program.

Idelsis is NCCPA board licensed and certified in the state of Florida. She has been part of the Florida Association of Physician Assistants since 2005. As an OB/GYN physician assistant, she sees a full spectrum of obstetrical and gynecological patients and is also part of our pelvic floor rehabilitation program. Idelsis also runs the Esthetics in our office, and specializes in Fillers and Botox.

Idelsis has one daughter. Outside of work she enjoys wining and dining and spending time with her family. She notes that, “Upon graduation I joined the practice at South Miami OB GYN Associates, and I do have to admit it was one of the best decisions I’ve ever made, I feel honored to be part of such an amazing and caring team.”

“Dr. Chi was amazing- she coached me through the labor. A true professional with the experience every new mommy needs. I will continue to see her for my future appointments.”

Denay Z.

“Everyone is so nice at the practise. I have been going there for approximately 10 years now and even though I live a good 45 minutes away, I wouldn’t change doctors. Dr. Chi is amazing! She delivered both my sons and I had a great experience with her as well as with the other doctors at the practise.”

“Dr. Horst is INCREDIBLE! His attention to detail, bedside manner and amazing memory are just a few of his top qualities. I can’t properly express my absolute gratitude to have him as my Dr.”
