What parents are saying
Posted on Google BorisTrustindex verifies that the original source of the review is Google. Griselda is a fantastic instructor. She taught my 3 year old daughter how to swim in a few sessions. My daughter looks forward to each lesson. Griselda is professional and patient. Highly recommend.Posted on Google Victoria LipkinTrustindex verifies that the original source of the review is Google. We are so happy with Griselda as our daughter’s swim instructor. She started lessons at 2 years old and is now 3, and the progress has been incredible. She swims so well and genuinely loves being in the water. Griselda is patient, caring, professional, and truly amazing with children. Her method is very effective, and she also gave us the tools and guidance to continue practicing with our daughter outside of lessons, which helped so much. Our whole family loves her, and we recommend her to everyone around us. She is truly wonderful and makes children feel confident and safe in the water. Thank you for everything!Posted on Google Alice SerfatiTrustindex verifies that the original source of the review is Google. Griselda is above and beyond!! My daughter did not like her previous swim teacher and from the first class with Griselda she loved it and learned so much so quickly. Griselda is very professional, understands and connects with her students, and teaches young kids to swim and float by themselves. I highly recommend Griselda for anyone considering!Posted on Google Ceceil MTrustindex verifies that the original source of the review is Google. Griselda has completely changed my 3 and 5 year olds perspective on the pool and swimming! They went from being fearful and nervous in the water to swimming with confidence and excitement!! Her patience, kindness, and encouraging teaching style made all the difference and we are so grateful for the impact she has had and highly recommend her to any family!!Posted on Google Lauren GTrustindex verifies that the original source of the review is Google. My family and I highly recommend Griselda and Swimful Kids! My two kids started swimming lessons with Griselda as babies, and now at 2.5 and 5 years old, they absolutely love the water and their weekly lessons. They’ve built a strong foundation and continue to grow their skills with her. Beyond swimming skills, they’re learning important lifelong water safety habits in a fun and encouraging environment. Griselda is patient, positive, and engaging. She has a wonderful way with children and is always smiling!Posted on Google Daniella MargelTrustindex verifies that the original source of the review is Google. Amazing swim instructors — so knowledgeable, patient, and incredibly kid-friendly! We’re from out of town and will definitely be coming back for lessons every time we’re here.Posted on Google K SZTrustindex verifies that the original source of the review is Google. Griselda has been an amazing for our 3yo daughter! She spent 8 weeks with Gris this summer and has learned more with her than she has in over a year at a local swim school. Our daughter is more confident in the water, loves jumping and diving in the water and has overcome her fear of putting her head in the water. Gris is super communicative and quick to respond to all of our questions and concerns . She is patient, gentle and so sweet with the kids and us! We feel so lucky to have found her !Posted on Google Sabrina LewisTrustindex verifies that the original source of the review is Google. Griselda is the absolute BEST swim teacher there is! I have 3 kids and have seen many swim instructors- none as wonderful as she! She is a magician and so sweet and patient! If you want your kiddo swimming in no time, DEF hire her, you won’t be sorry :)Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
