ABOUT THE INSTRUCTORS
Irina “Pina” Pinkusevich found her calling as a dog groomer after immigrating from Ukraine in 1989 and working part-time as a bather. 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. She also triumphed at the Winner’s Circle Jackpot in 2011 and earned the World Dog Show’s World Champion Award. From 2008 to 2013, Pina was a proud member of GroomTeam USA, competing internationally and helping her team win a Silver and two Gold medals.
Beyond her achievements in grooming, Pina is celebrated as a judge, instructor, and speaker. In 2014, she was honored with the Cardinal Crystal Award for Judge of the Year and the Barkleigh Honors Award for Up & Coming Speaker of the Year. As a National Certified Master Groomer (NCMG) with the National Dog Groomers of America, she also served as a Certifier for many years.
Pina’s passion for education brings her around the world for conferences, seminars, and workshops, including the PM Mastery Series with Ann Martin. In 2021, she launched Niira to provide top-notch, affordable grooming tools. Her journey with Groom Haüs began at its inception, and in 2024, she officially joined as Education Director and co-owner.
Pina is also deeply involved with Kiyara Poodles, Kerryfield Kennels, and Krizma Kennels, where she has bred and co-owned numerous champion Poodles and Kerry Blue Terriers. Her dedication to excellence and education has made her a beloved, well-known, and respected figure in the grooming community for good reason.

I absolute love Gromm Haus and this course is amazing, like all those with Pina.
I only would like that there would be course history, because I am trying watch them more than once and it is difficult to find them. It would be perfect if there there application, where You can watch courses from the moment You stopped and even in offline mode.

I already try my best to do corrective grooming every day in the salon, but this is definitely going to up my skills 10 fold. I learned so much from these two, and they’re a fun duo to watch! I didn’t lose interest and I was just eating up all of the information they were explaining. I loved this webinar, 10/10
