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.

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.

The information and tips were awesome and very helpful. The filming is not so good, but it’s definitely worth the watch.
Groom Haüs –
Hi Mona, thanks for the feedback. Typically we would ask what exactly you thought was “not so good” about the production seeing as how we are known for our high quality, but this was shot a few years ago so our setup and quality has changed quite a bit since then.
Rosann Garwood –

Liz Hampton –
Loved this webinar! Very informative and the lighting/camera work was excellent! I will definitely stay tuned for upcoming classes!
Kathy Awalt –
The webinar was good and I picked up some tips to further improve my skills. However, I live in a rural community and pet owners want short or puppy cut, whatever length that may be. In this area they do not want cuts that require work on their part. I dare to dream of a groom where I could color a tail or even use a flat iron. Keep inspiring and stirring us to grow in our skills.

Excellent!! Communication and content was excellent!! Looking forward to watching again!!
