MERRY CHRISTMAS 🎄 from the whole KMMG family to yours. It’s rare these days to all be together, what a joy it was to celebrate on the square for our company Christmas dinner. Thanks Doc, for not only taking care of your patients, but your staff as well. You’re a gift to us all. 🎁

We had to say our goodbyes to Alyssa, who’s been with us for the past 4+years here at KMMG, as she continues on to another new venture/field of sales. Your s***k and spirit will be missed and we wish you all the best in your endeavors to becoming CEO soon.

May we all congratulate that second MD in the family, Dr. John Matechak on his first official shift in the field. Who knows, MABYE someday we will get you at KMMG to practice medicine alongside with your dad. Make us proud, although you already have!

Our very own Dr. Matechak got to “hood”/robe his first born son John E today with the title DOCTOR. My word what a week! Congratulations John E. We here at KMMG are so very proud of you. Now go and keep to the code and do no harm!

HAPPY BIRTHDAY to our Dr. Matechak. We all here as your KMMG team and patients wish you the best day today and year to come. It’s amazing how one man can stay so cool, calm and collective while running a successful practice, raising a family, keep hobbies with biking/skiing and going over and beyond to help those in need. You show us there is 25 hours in a day, just keep swimming. 🎂

🎂 HAPPY BIRTHDAY this week to Nancy, our NP who has become quite the loved one with our patients these past couple years. She herself is patient, kind and thorough with a listening ear. Also celebrating a birthday is our newest employee Samantha. She has helped us seal the gap and make our circle complete. Happy birthday ladies.

It’s nearly impossible for our staff to be together in one place at the same time but we took advantage while all dressed in uniform. Missing our Dr. Matechak and Nancy Martinez NP for the photo. We welcome our newest employee Samantha to the team.
