She honed her skills at some of New York’s finest grooming salons before stepping into the competitive grooming scene in 2006. Pina quickly made a name for herself, winning prestigious titles like Best In Show, Best All Around Groomer, the Lynne Carver Award (twice), and the Liz Paul Memorial Award.

What a great seminar!!! This seminar had such a wide range of educational information- from corrective grooming, to the 5 stages of hair growth, to scissor techniques and different types of shears and their uses. As well as so much more! Pina and Jonathan were not only entertaining, but the combination of their skill and knowledge made this 4 hour seminar extraordinary. Thank you!

Love hearing them talk about grooming history. The most important part in my opinion was the topic about grooming and legislation. I think we need a whole episode about this topic. Grooming being the last vocation/profession that doesn’t require a license and in my opinion we should keep government away from grooming.
It’s not needed, just look at our own doctors , fully licensed and insured and corrupt AF.

Pina and Jonathan were on point with client drop off skit. It was funny, very real, and practical. The seminar felt relatable and applicable to everyday grooming. I will rewatch it multiple times to focus on what Pina or Jonathan is doing as at they were working simultaneously on different parts of the dog sometimes.
