Meet the Staff

JDB Office CloseJim DeBonis
Chief Operating Officer

Jim DeBonis is our Chief Operating Officer, overseeing all aspects of Trentadue Winery. He is chiefly responsible for creating and executing strategic business plans which ensure the Trentadue legacy lives on for years to come.

Born and raised in Sonoma County, he grew up in this rich agricultural region and was exposed to vineyards and wine at a very early age.  Working on his grandfather’s ranch he led his first crew at just 12 years of age. The combination of Jim’s early exposure to winemaking and viticulture, years of study and leadership experience and passion for wine and commitment to the region makes him an ideal leader of our winery family.

“Being part of the wine industry is core to my life.  The magical blend of art and science, from the vineyard to the dining room table, culminating in the enjoyment of your wine with friends and family is one of the most satisfying things in life.”  After completing his Bachelor of Science degree at the University of San Francisco and short stint in the high tech industry, Jim returned to where his heart was and started his career in the wine industry in 1987 as Cellar Master at Simi Winery.  Jim continued his studies in Winemaking and Viticulture at UC Davis and gained additional responsibilities, becoming a Vice President of Winemaking and Vineyards in 1991.  “I had the unique opportunity to develop vineyards in both Alexander and Russian River Valleys and lead teams to create world class award winning wines from them.”  Jim’s responsibilities continued to expand and he joined the team overseeing worldwide operations for Louis Vuitton Moet Hennessy, Simi’s parent company, in 1996.  Jim went on to hold executive positions at Constellation Brands, Allied Domecq, and Beam Wine Estates.  In 2008 he founded Ascentia Wine Estates which acquired local wineries Geyser Peak, Buena Vista, Gary Farrell and Washington Wineries, Columbia and Covey Run.  “In 2012 I realized I was spending most of my time in the board room or managing investor and banking relationships, I knew I had to get back to where my heart was, in the vineyards and in the cellars.”

Jim began consulting with small family owned wineries, helping them with everything from new winery design and layout to renovating older facilities.   “While back in a hands-on role I realized I was still missing something essential to me, which was being part of a great team making great wines.  When the opportunity at Trentadue Winery presented itself, I did not hesitate for one second.”  Jim started at Trentadue at the beginning of 2017. 

“Having been entrusted with the Trentadue heritage and being part of a great team making outstanding wines from the Estate in the heart of Alexander Valley, I couldn’t be happier.”

MIRO TCHOLAKOV Miro Head Shot
Vice President of Winemaking Operations 

Miro Tcholakov is our Vice President and Director of Winemaking Operations, overseeing all aspects of winemaking; including custom crush and bottling. Chiefly responsible for reinvigorating the Trentadue brand when he came aboard in 1999, Miro has worked tirelessly to take our wines to a new level of quality and prestige.

Born and raised in northern Bulgaria, a region with many millennia of winemaking history, he was exposed to wine and winemaking at a very early age. At his grandfather’s side, he learned how to make wine in the tradition of the generations that came before him. The combination of Miro’s early exposure to winemaking, years of study and experience, and passion for the art makes him a vital part of our winery family.

“Making wine has been a lifelong dream of mine. After completing my studies in 1990 at the higher Institute of Agriculture in Bulgaria in Agronomy/Viticulture, I traveled to California on an Exchange program in wine business. I continued my education by attending Santa Rosa Junior College and UC Davis, focusing on specific courses in Winemaking and management. My internship started at Dry Creek Vineyards in the summer of 1990 and in nine years of employment, I transitioned through the ranks of Cellar Master and Assistant Winemaker. It was during this time that I fell in love with two distinctively California varietals; Zinfandel and especially Petite Sirah.

I decided to move on and start my career as a head winemaker, accepting an offer from Trentadue Winery in 1999 to take over their winemaking operation. That new opportunity added to my excitement about Zinfandel and Petite Sirah, which have been two long standing staple varietals at Trentadue.

My passionate love affair with Zin and Petite Sirah lead to my election to the Board of Directors of ZAP (Zinfandel Advocates and Producers) and also to the Board of Directors and currently the President of PS(Petite Sirah) I Love you-a nonprofit organization that I helped establish 13 years ago.”

MARYANN PELLEGRINI, ControllerMaryann Head Shot

Maryann Pellegrini is our Controller at Trentadue Winery, whose wide ranging responsibilities include financial planning, cash flow forecasting, department budgets, accounting, AR/AP, payroll and taxes. Her duties expand further as she is a tremendous support system for all winery departments, most importantly Wholesale Sales.

No stranger to agriculture, Maryann grew up in a multigenerational Central Valley family farming operation that primarily grew row crops. At a young age Maryann was required to help on the farm and that is when her passion for agriculture began to develop. She spent some time driving tractors and was also put to work in the office where she learned to reconcile bank accounts, enter and pay bills, and complete payroll… all before graduating from high school. This is where Maryann first realized that business finance is what she wanted to do for the rest of her life.  After graduating from Cal Poly, San Luis Obispo in 2009, with a double major; Bachelor of Science degrees in Agricultural Business and Agricultural Science, Maryann began her career as an Accounting Assistant for a Central Valley farming operation similar to the one her family owns. Fate brought her to Sonoma County and to Trentadue Winery in 2010, when was hired as our Accounting Manager. She quickly was promoted to our Controller and has been an invaluable asset to our team ever since.

Maryann has quickly put down roots in the area, purchasing a home in Santa Rosa with her husband, Marco Pellegrini. The two were married at Trentadue Winery in June 2014!

ROYALENE MANCINI, Tasting Room Manager Royalene Head Shot

Royalene Mancini is the Tasting Room Manager at Trentadue Winery, supervising all Direct to Consumer sales. She brings extensive experience in hospitality management to Trentadue, where she has flourished since joining our staff in 2010. Her background includes management positions with wineries such as Chateau Souverain, Landmark and Rosenblum Cellars, and has widespread experience with event production.     

A native Californian, she grew up in a family ranching business in Central California, then attended UCLA where she focused her studies in Health Sciences. As difficult as it was to leave the beaches of Southern California she pursued a career (totally alien to her education), with a well-known artist in the ceramics industry, based out of Healdsburg. Falling in love with Healdsburg - known as the “burg” back then –she decided to stay on.  

She is a beloved member of our management team, and says that the favorite part of her position is working with her fellow employees. “It is a pleasure coming to work every day, we have a lot of fun and the surroundings aren’t bad either!” She is a professional entertainer and head chef of our Trentadue Winery Kitchen, sharing with us her knowledge of superior ingredients and recipes dating back generations or those she has created in her own kitchen. Gardening, cycling and fine dining take up a lot of her “down time” now that her daughter is away at OSU, where her studies are in Public Health & Human Sciences.
